  • Project Management.

    A new project management system allows one to:

    • show the list and info about existing projects
    • execute apps, load scenes in the Viewer app, load scene files in Blender.
    • create and configure new applications, optionally using prefabricated app/scene starter files to simplify creating new applications
    • build applications, create versions suitable for deployment on a server
    • convert application resources (textures, sounds and video) to alternative formats
    • automatically reexport all application scenes including json and html files

    There are two methods to manage projects: by using project.py utility which has a simple self-documented command line interface, or using a GUI web application, which is run on the developer server. This server does not require any additional configuration and as before is executed by the Open SDK button in Blender.

    The project management system works on all operating systems, however, some operations may require additional dependencies. To find out more about the configuration of this system check out the following topic in documentation.

  • Controlling armature bones.

  • Skeletal animation now takes into account the relative translation of an armature and a skinned object.

    Native Blender’s behavior is now supported. There is now no need to position an armature and an animated object in the same place and with the same rotation and scale.

  • Independent translation, rotation and scale animations are now supported.

    The animation system no more forces keyframes to be present in every channel, which makes it possible to save original values in unused channels or change them with API.

  • World background support.

    Background and sky can be enabled with the Sky Settings > Render Sky option under the World tab. It is turned off by default.

  • The Uranium physics engine now consists of two modules.

    There are now two physics modules instead of one: uranium.js - the engine’s code and uranium.js.mem - the file for memory initialization. Both modules must be placed in the same directory.

  • The glow effect together with its related components was renamed to Outline.

    The new name better describes the principle of this effect: highlighting objects' edges.

  • Limiting the camera translation using the "append_semi_stiff_cam" method of the "constraints.js" module is now possible only for the "EYE" type.

  • Local Development Server in Blender changes.

    Now, instead of the standard Python SimpleHTTPServer, the Tornado web server is used as the local development server. The new server has greater performance and it also offers more options to disable browser cache.

  • Keyboard controls for sliders in the Viewer application were added.

    You can now control sliders with < and > keys.

  • Changes in the "update_object_animation" method of the "animation.js" module.

    The optional "force_update" parameter was added. It forces animated objects to be updated even when their animation is not being played back.

  • API changes in the mouse.js module.

    The enable_mouse_hover_outline and disable_mouse_hover_outline methods were added.

    The following methods were declared deprecated and will be removed in the next releases: enable_mouse_hover_glow and disable_mouse_hover_glow.

  • API changes in the scenes.js module.

    The outlining_is_enabled, set_outline_intensity, get_outline_intensity, apply_outline_anim, apply_outline_anim_def, clear_outline_anim, set_outline_color and get_outline_color methods were added.

  • Some settings were changed in the Object > Blend4Web panel.

    The Enable Outline option was added to enable using the outline effect on the given object. Also, the Outline on Select option was added to activate glow animation when the object is selected (previously this behavior was defined by the Selectable flag).

  • New settings were added to the Scene > Blend4Web panel.

    The Enable Object Outlining option was added to control the overall possibility of outlining. Similarly, the new Enable Object Selectable option controls the overall possibility of objects' selection.

  • Now the following object properties: Apply Scale, Apply Modifiers, Export Vertex Animation, Export Edited Normals and Export Shape Keys are mutually exclusive.

  • API changes in modules.

    The new is_armature method was added to the API of the util.js module. It checks if the given object is of the ARMATURE type.

    The new get_parent method was added to the API of the constraints.js module. It returns the parent object of the given object.


  • Fixed a bug in the "anchors.js" module which caused objects' descriptions to disappear.

  • Fixed a bug in the Animation Baker script that occurred when there were armature objects in hidden layers.

  • Fixed the camera’s behavior while using "append_semi_stiff_cam" method of the "constraints.js" module.

These anchors can be of three different types: "Annotations" - information from object’s meta-tags is used, "Custom Element" - a custom HTML-element from the current web-page can be used as annotation, "Generic" - an invisible anchor with coordinates calculated using anchors.js module API.

  • Animation and API methods for Value and RGB nodes in node materials.

    Now it is possible to animate not only Value nodes but also RGB nodes. Also, the corresponding API methods for changing such nodes were added in the objects.js module.

  • New "Code Snippets" application.

    This application was created to simplify access to the examples of engine’s functionality. It is also possible to look at the examples' scripts. This application can be launched from the index.html file located in the Blend4Web SDK’s root directory.

  • New control functions for the Glow effect.

    New APIs were added in the scenes module: get_glow_intensity() and get_glow_color().

  • Improvements in the Scene Viewer.

    Design of the "Home" button was changed. A new button "All objects selectable" was added. It allows to turn off automatic "Selectable" option assignment for all scene objects. Also, it is now possible to see the total number of shaders on the loaded scene.

  • Dynamic copying of scene objects (instancing).

    Now it is possible to dynamically copy and remove scene objects (to create and remove instances).

  • Handling errors related to the B4W_PARALLAX Blend4Web-specific node.

    In case of incorrect usage of the B4W_PARALLAX node, an export error warning is generated.

    There are now new options in the application builder: -j and -c. They add scripts and styles correspondingly to the exceptions in order to be not compiled.

  • Experimental Blend4Web render engine.

    It can be turned on in the addon settings using the "Register Blend4Web render engine (Experimental)" flag. This mode is designed to simplify customization of scene properties. Also, it simplifies the interface by removing unsupported panels. At the moment, it is not possible to edit shader node tree in the Blend4Web render mode.


  • Origin for counting off the camera limits has been changed.

    Setting camera movement limits via API now perfectly corresponds to values measured in the engine’s coordinate system. Setting horizontal limits for the TARGET camera in the Blender’s world space has been changed. Thus, it may require changeovers for old scenes.

  • Documentation update for the camera settings.

  • Horizontal and vertical limits of the camera rotation are completely independent from each other.

  • Some APIs in the camera.js module were changed.

    APIs of the camera.js module have undergone a number of changes.

    New methods were added: is_target_camera, is_eye_camera, is_hover_camera, rotate_camera, rotate_target_camera, rotate_eye_camera, rotate_hover_camera, get_camera_angles, hover_cam_set_translation.

    The following methods were declared as deprecated and will be removed in the next releases: rotate_pivot, rotate_hover_cam, rotate, set_eye_params, get_angles, translate_hover_cam_v, set_hover_cam_angle.

    The set_ortho_scale and get_ortho_scale methods now print error message when they are applied to the Orthographic camera. The behavior of the get_hover_angle_limits method was also changed. This method now returns angle limits for the HOVER camera in the [down, up] format instead of [up, down] as it was before.

  • The lighting system was significantly optimized.

    Many of the lamp props are calculated at the compile time now. Now, there is no 4 lamp restriction is imposed for some mobile devices.

  • The HTML layout method was changed for apps using the app module.

    Now, upon initializing an application using the app.js module, the dimensions of the created <canvas> element are completely determined by the size of the container element. Thus, if a <div> element is used as a container, the size of <canvas> will be zero by default since div’s default size is zero. You can set correct parameters for the container with CSS and inline-style. Also, you have to use resize_to_container() method from the app module when the container is changed. The same effect may be achieved if the autoresize option is set upon initializing the application (in the app.init() function). The low level method for changing the element’s dimensions with main.resize() function is still supported.

  • Now, the enable_controls() function from the app module should be called without any parameters.

  • Deprecated API methods were removed.

    textures.js module : stop_video.

    scenes.js module: add_object, get_screen_scenes, set_light_pos, set_light_direction, set_dir_light_color, get_lights_names, remove_all, check_collision, check_ray_hit, get_appended_objs, get_object_by_empty_name.

    main.js module: set_shaders_dir, set_texture_quality.

    data.js module: get_bpy_world.

    controls.js module: sensor_make_positive, sensor_make_negative.

    camera.js module: change_eye_target_dist (deprecated MS_CONTROLS was also removed).

  • There are now new conditions to allow changing object’s position via API.

    The functions from the transform.js module related to changing object position can be now applied to dynamic objects only.

  • You can now use TEXTURE nodes without textures.

    In this case the rendering of the node material completely corresponds to Blender.

  • Updated the procedure of compatibility checks for versions of exported files and the engine itself.

    The engine will report about the scene’s incompatibility by printing messages in the browser console.

  • The "Do Not Batch" property was renamed to "Force Dynamic Object"

    This option instructs the engine that the object must be dynamic regardless of other settings. Now its name is more clear.

    This property allows adding a version to the scripts and styles of the compiled application.


  • Now it is possible to add options with the same names via browser address bar.

    A new optional parameter allow_param_array is added to get_url_params() function of app module. It is set to false by default. Setting this parameter to true leads to a merge of identical functions into a massive, other way the last one will be used.

  • Improved ``Background Music`` speaker.

    Now the user can specify parameters of delay and playback time.

  • Blend-file now includes special Blend4Web nodes by default.

  • Support for high definition displays (HIDPI, Retina).

    The HIDPI mode allows to achieve considerable improvement of picture quality on devices with high resolution. This mode is activated automatically upon application startup if ULTRA quality profile has been selected. If necessary, high resolution can be turned on for other quality profiles.

  • Support orthographic camera scaling.

    An API to change the Orthographic camera scale has been added (Orthographic scale in Blender).

  • "autorotate" option has been added to the webplayer.

    The option autorotate is used to turn on the automatic camera rotation as soon as the scene loads.

  • Simplified keyboard control mode has been added to function "enable_camera_controls.

    The mode is enabled by passing the optional parameter disable_letter_controls Thus, the keyboard controls with letter keys (WASD and so on) will be turned off. This feature can be used in cases when you need to use the letter keys for purposes other than moving the camera.

  • Support for gyroscope on mobile devices.

    To work with gyroscope on mobile devices the two sensors was implemented. The first sensor allows to operate with current device position compared with the previous one (position delta). It’s created by using the function create_gyro_delta_sensor from "controls.js" module. The second sensor returns current device angle and created by create_gyro_angles_sensor from "controls.js" module. It’s worth to mention that all angles are given in radians. Also the special addon "gyroscope.js" was created. This addon implements simple camera movements due to device rotation. You can find an example of using such feature in our Viewer application by selecting the "Gyroscope" menu option.

  • New ``Do not Render`` property has been added to material settings.

    Enabling the property allows to hide parts of the scene objects which use such material.

    It’s now possible to append meta tag information to scenes and objects in Blender. Possible tags for scenes are "title" and "description". Possible tags for objects are "title", "description" and "category".

  • Added support for execution of user-defined functions every frame.

    To help users to create sophisticated application the new function append_loop_cb has been added to "main.js" module. This function allows to execute given callback every frame. This callback has two parameters: time since the application start and time delta between current and previous frame. Both parameters are in seconds. To cancel the callback execution every frame you should remove it by using the remove_loop_cb function from the module "main.js".

  • Added support for simple preloader screen animation.

    To create an application with animated preloader pass an option "preloader_fadeout" with the value "true" to the function create_simple_preloader from "preloader.js" module.

  • Changed camera autorotation behavior (experimental).

    If the camera limits are present, the camera smoothly slows down when approaching the limits, then moves in the opposite direction.

  • The usage of ``Special: Collision`` property was changed.

    Earlier, enabling the option automatically resulted in objects' hiding. Now, to do the same thing, you have to specify Do not Render property in the material settings.

  • Changed suffix for converted media files.

    Old *.lossconv.* suffix was replaced by *.altconv.*.

  • Behavior of "Do not render" object property was changed.

    We have added mipmapping support for Canvas textures.

  • Full support for the "MAPPING" node.

    Now all Vector type options available for the MAPPING node are supported, including Texture, Point, Vector and Normal.

  • Glow on mouse over.

    API in the mouse.js module were created for the effect of outlining the objects under the mouse pointer. Also, for purposes of controlling this effect, enable_mouse_hover_glow() and disable_mouse_hover_glow() methods were added. The objects should have Object > Blend4Web > Selectable checkbox enabled.

  • A brand new app building system.

    Now, the users can develop their apps right in the SDK thanks to the new project.py utility. This script makes it possible to build the apps together with the engine, to minify JavaScript and CSS files and to export the final apps to be deployed on a server.


  • Removed support for deprecated "UV translation velocity" texture settings.

    We recommend to use node materials instead.

  • Removed deprecated "Levels of Detail" user interface.

    This functionality can be used through Blender’s standard "Levels of Detail" tool.

  • A mouseup event is now fired when the mouse pointer is leaving the app viewport.

    So the problem with broken camera controls is no longer observed.

  • Error message about "Clear parent inverse" is no more shown.

    Before, when using parenting, it was required to reset translation, rotation and scale of child objects (Object > Parent > Clear Parent Inverse). Now such transformation is natively supported by the engine.

  • "Apply scale" option no longer applies modifiers.

    As before, Apply modifiers should be used in order to apply modifiers.

  • Use of normal maps in node materials no longer requires a Material or Extended Material node.

    In some cases (e.g. refraction) normal maps can be used in shadeless materials.


  • Fixed audio playback error occurred when using NLA.

    This happened due to insufficient float number precision.

  • Fixed incorrect rendering of light sources on mobile devices.

  • Layering shadows is fixed when multiple active light sources are present.

    Now the shadows are calculated like in Blender, that is areas illuminated by other light sources are not darkened.

  • Node material rendering error has been fixed.

    The error occurred when a MATERIAL node (or MATERIAL_EXT) with a linked (from another .blend file) material was used.

  • Animation baker ("B4W Animation Bake" operator) no longer resets an armature pose.

    Now, when using the animation baking tool, the armature pose is being left intact.

  • Camera panning.

    In the mode when the camera is rotating around a single point (Target) the users now have the ability to move the pivot point within the view plane (so called camera panning) while the right or middle mouse buttons are pressed. This function is turned on by default and can be turned off in Blender settings at need.

  • New camera control mode - Hover.

    The Hover mode is now available when the camera is gliding over the horizontal plane (including zooming in and out). This camera mode makes it possible to realize scenarios for a convenient viewing of scenes which are spread in two dimensions (rooms, game levels).

  • The SDK now contains a root index HTML webpage for simplifying navigation within the distribution.

  • The resource converter now has the ability to convert videos.

  • We have added a build system which was absent in previous public SDK distributions.

  • The export Strict mode is implemented in the add-on.

    Activating Strict mode gives the possibility to display all possible errors and warnings connected with incorrect scene settings. The option is useful for final scene debugging for getting the most correct and optimized resource files.

  • Audio playback support for iOS devices.


  • The webplayer’s "bg" parameter is renamed to "fallback_image".

    This option also has changed its behavior. If the fallback_image is defined the error message that WebGL is unavailable is not shown anymore, instead the user sees just the image.

  • If there are no sound sources in the scene the sound mute button is no longer shown in the webplayer.

  • Generic materials workflow is now more predictable.

  • The "mouse_down" sensor provides the code of the mouse button pressed. This code can be obtained from the payload sensor’s parameter.

    Using UV layers is no more required for normal maps.

  • Fixed the problem with the wrong path to the physics engine in the webplayer.

    This error arose when uranium.js was moved out of the directory containing the main HTML file of the webplayer.

  • In the add-on we have fixed the problem with packed textures. Export crashed when the "Automatically Pack Into .blend" option was enabled.

Known Issues

  • Problems with updating of the add-on.

    It’s strongly advised to restart Blender after installing a newer version of Addon/SDK.

  • Added support for the "Do not export" option for particle systems.

  • Improved stability on iOS devices.


  • Changed SDK path setting for HTML export.

    It’s now needed to set the SDK path setting for HTML export to SDK root directory. Earlier it was required to provide the full path to embed application. Pay attention, the old behavior is not supported anymore.

  • Deprecated the "UV translation velocity" option.

    The option will be removed since version 14.12.

  • Removed option "Do not export" from the "Object data" panel.

  • Removed "Blend4Web > Animation > Cyclic" option from the object properties panel.

    Instead, one should use Blend4Web > Animation > Behavior option located in the same place. Scenes with default animations may work incorrectly, so they need behavior property to be set to Cyclic.

  • Modified SSAO algorithm realization.

    The new implementation is much faster and shows better quality. The settings of the algorithm are changed too. For more info see the manual section.


  • Fixed rendering error for HALO materials.

  • Fixed a rendering error when an object with the enabled "Force Dynamic Object" property has a parent object.

  • Fixed error with keyboard shortcuts in Blender.

    Fixed error with inability to assign keyboard shortcuts in Blender for export menu items:File->Export->Blend4Web(.json) and File->Export->Blend4Web(.html).

  • Fixed crash when loading textures with size exceeding device limits.

  • Fixed node material errors resulting in unstable engine behavior.

  • Fixed error in node materials that contained complex Node Groups.

  • Fixed errors of shaders compilation on devices with mobile graphics Qualcomm Adreno 305.

  • Fixed rendering error when using REFRACTION nodes in transparent materials.

  • Fixed an issue in "B4W Vertex Anim Baker" tool when current frame reset was occurred after using bake.

Known Issues

  • Problems with updating of the add-on.

    It’s strongly advised to restart Blender after installing a newer version of Addon/SDK.

  • Normal maps don’t work for Generated texture type.

    It is necessary to use UV mapping for normal maps.



  • ABSOLUTE type support for the MATH node.

  • Support for LEVELS_OF_QUALITY special node.

    Allows to control the material’s complexity depending on the quality profile which is specified by the user upon engine start.

  • Support for SMOOTHSTEP special node.

    Simplifies the creation of some effects in node materials.

  • Node groups support.

    Node groups allow the sharing of node blocks between materials.

  • The ability to output intermediate rendering results for debugging.

    The rendering result for a certain stage can be now output above the main picture. This can be set up in the config.js module through the debug_subs options.

  • The logic for controlling Blender’s NLA animation using a visual editor has been implemented.

    The NLA Script tool has been added to Blender’s interface to allow the implementing of simple scenarios using visual blocks, for example playing an animation in response to the user actions.

  • Multiple sensor system improvements.

    It is now permitted to register sensor manifolds globally using a controls module method with no connection to any object. To do this null should be passed into the corresponding API. The sensor logic is processed in a more predictable and robust way according to the sequence in which their manifolds are created. Callbacks of the user action events are now assigned using the register_<input_type>_events() functions. To these functions it is now possible to pass the prevent_default flag which allows to unblock the standard browser behavior for the corresponding events.

  • The Web Player now supports physics.

    Works only in the Web Player version where JSON files are loaded separately. Physics still not supported in the single HTML files.

  • Skeletal animation mixing is now supported.

    The animation.js module now contains API for smooth transitions between skeletal animations: get_skel_mix_factor() - for getting the current mixing factor value and set_skel_mix_factor() - for setting it.

  • The Value node can now be animated in node materials.

    The functionality is similar to other animation types. Working in NLA is also supported.

  • Diffuse and Specular lamp’s properties are now supported.

  • The possibility to render a transparent object above other objects on the scene.

    Activated with the Render above all checkbox for transparent materials (i.e. not Opaque).

  • Scale is applied automatically to the object mesh.

    Activated by enabling the Apply scale checkbox in the object settings.

  • High quality profile (including shadows, dynamic reflections and anti-aliasing) has been implemented for iOS.


  • Shadow rendering improved.

    Shadow rendering system is significantly changed: it is now based on the Stable Cascaded Shadow Maps technique. This technique allows to greatly diminish the flickering of shadow edges when the camera moves. Smoothing is implemented between cascades. Also shadows of the last cascade fade out at distancing. Softened shadows are rendered using the Percentage Closer Shadows technique. The shadows' user settings are reworked and simplified. Now its possible to tweak the size of shadow maps, blur ratio and the setting for removing self-shadowing artifacts. The new settings are documented in detail.

  • In the Web Player graphics quality settings are now saved independently for each scene.

  • The behavior of the app configuration parameters has been changed: physics_uranium_path, smaa_search_texture_path and smaa_area_texture_path.

    These parameters are now calculated automatically depending on the running HTML files location, if they haven’t been overridden during the app’s initialization.

  • Transition is completed to the system of modules which are linked via b4w.require() call.

    This also means that starting form the current version its impossible to call modules in the engine’s release version using the old b4w.<module> namespaces. For compatibility purposes the ns_compat.js add-on has been implemented, the linking of which allows to restore the old behavior.

  • The Web Player’s control panel can now be hidden.

  • Skeletal animation is now applied to armature objects only.

    There is no need to apply skeletal animation to MESH objects. If they are linked to some animated armature, their skinning will be automatic.

  • Demos and tutorials are updated according to the newly implemented features.


  • The preloader didn’t disappear in case of a loading error (texture or sound file).
  • Lagging during scaling and turning on mobile devices is fixed.
  • TARGET-type camera shimmering has been removed for small turnings.
  • EYE-type camera controls was fixed for mobile devices.
  • The Farm demo controls are improved for Safari browser.
  • Errors concerning using the unsupported shading models in node materials are now fixed.
  • "Selectable" option now works for the objects without materials.
  • There is no longer need to enable "Force Dynamic Object" for the objects that are animated using NLA.
  • The particle system error when the object being instanced is parented to another object, has been fixed.

Known Issues

  • Problems with updating of the add-on.

    It’s strongly advised to restart Blender after installing a newer version of Addon/SDK.

  • Armature animation mixing doesn’t work with some browsers.

    If skeletal animation mixing API brings unexpected errors, it is necessary to override standard Math.sign function as follows:

    var m_util  = require("util");
    Math.sign = m_util.sign;
