# Scene Settings¶

All the parameters that define the look and behavior of the whole scene (and not just a single object) are found on the three panels: the Render panel, the Scene panel and the World panel.

## Render Panel¶

All scene parameters that concern the image rendering are found on this panel.

### Development Tools¶

Development Server settings. Described thoroughly in its own section.

This panel contains various shading options.

Set Recommended Options

This button is used to achieve maximum consistency between the look of a 3D scene in Blender viewport and in web browser. Pressing this button:

• switches material mode to GLSL,
• switches viewport shading mode to Material and
• sets the main camera fit to Vertical.
This option turns on and off World Space Shading (world space interpretation of lighting data will be used for object shading). Disabled by default.

Shadows settings. Described thoroughly in its own section.

### Reflections and Refractions¶

Reflection and refraction effect settings.

Reflection
Reflection effect settings. Can be set to ON, OFF or AUTO. Set to ON by default.
Refraction
Refraction effect settings. Can be set to ON, OFF or AUTO. Set to AUTO by default.
Quality
Quality settings for the reflection effect. Can be set to HIGH (the highest reflection quality), MEDIUM (medium quality) or to LOW (the lowest quality). Set to MEDIUM by default.

### Object Outlining¶

Outlining effect settings. Described thoroughly in its own section.

### Glow Materials¶

Glow Material effect settings. Described thoroughly in its own section.

Note

For dynamically loaded objects, AUTO setting is interpreted as OFF, if no materials with glow are present in the scene. If you are using dynamic loading, you should set this parameter to ON.

### Anti-Aliasing¶

Anti-Aliasing settings. Described thoroughly in its own section.

### Anisotropic Filtering¶

This parameter can be used to enable or disable anisotropic filtering and also to set the number of texture samples used for it. By default, anisotropic filtering is disabled.

Available values: 16x, 8x, 4x, 2x and OFF (default value).

### Bloom¶

Bloom effect settings. Described thoroughly in its own section.

### Motion Blur¶

## Scene Panel¶

The settings that concern scene behavior, including audio, physics and animation settings, are found on this panel.

### Scene¶

Scene settings.

Camera
A camera that is used to render the scene.

### Units¶

Sets the measurement units used in the scene.

### Audio¶

Audio settings.

Volume
The master volume of the sound in the application. This value can vary between 0 and 100. Default value is 1.0.
Distance Model

The distance model used for calculating distance attenuation. Following models are supported by the engine:

None - no distance model is used, the sound has constant volume regardless of the distance.

Exponent Clamped - a clamped exponential distance model.

Linear Clamped - a clamped linear distance model.

Inverse Clamped - a clamped inverse distance model.

The following models are partially supported (work the same way the corresponding Clamped-type models):

Exponent

Linear

Inverse

This parameter is set to Inverse Clamped by default.

Speed
This parameter sets the speed of sound used for Doppler effect calculation. Its value is measured in meters per second and is set to 343.3 by default.
Doppler
This sets the pitch factor for Doppler effect calculation. Its default value if 1.0.
Dynamic Compressor
Compress audio signal’s dynamic range. This feature can be used to make the sound more rich and even. Disabled by default.
Threshold
If the amplitude of the audio signal exceeds the value specified by this parameter, the compressor will reduce its level. Set to -24 dB by default.
Knee
The interval below the threshold where the response curve switches to the decreasing mode. Set to 30 by default.
Ratio
Amount of gain reduction. Set to 12 by default.
Attack
Time (in seconds) that takes the compressor to reduce gain by 10 dB. Set to 0.003 by default.
Release
Time (in seconds) that takes the compressor to increase gain by 10 dB. Set to 0.25 by default.

### Logic Editor¶

Settings for the use of the logic node trees (created in the logic editor) in the scene. Disabled by default.

Active Node Tree
Node tree that is used in the scene’s playback.

### NLA¶

Non-Linear Animation playback settings. Disabled by default.

Cyclic NLA
If this parameter is enabled, NLA animation will be repeated after it is finished.

### Meta Tags¶

Application’s meta tags. Can be set up in the same way as object meta tags.

Title
The title of the application.
Description

The description of the application. Can be a simple text or a link to a text file (if the Description Source parameter is set to the File value).

Note

If you are using a text file as description source, said file can be imported to Blender using a built-in Text Editor.

Description Source
The source of the application’s description. The description can be loaded from a file or specified directly in the Description field. This parameter can have one of the two values, Text and File, and it is set to Text by default.

### Physics¶

Physics settings.

Enable Physics
Allow using physics in the application. Enabled by default.

### Object Clustering & LOD¶

Settings for object clustering and Levels Of Detail.

Cluster Size
The size of the cluster used for batching (in meters). Can be used for optimization purposes. If this parameter is set to zero, the engine will try to combine all objects in the scene. Set to zero by default.
LOD Cluster Size Multiplier
This parameter is used to subdivide clusters (based on LOD distance specified individually for each object) into smaller ones to make transitions between different levels of detail less noticeable. The size of that smaller clusters is defined by object LOD distance multiplied by the value of this parameter. Higher values lead to bigger clusters which increases performance but makes transition between LODs more noticeable, while lower values make said transitions less noticeable at the cost of decreased performance. Can be used for optimization purposes. Set to 0.5 by default.
LOD Smooth Transitions

Defines what objects will use smooth transitions while switching their LOD levels. Has the following options:

• OFF - smooth transitions are disabled (fastest).
• NON-OPAQUE - use smooth transitions for objects with Add, Alpha Clip, Alpha Blend, Alpha Sort and Alpha Anti-Aliasing materials.
• ALL - smooth transitions will be used for all objects (slowest).

Choosing the “ALL” value can noticeably decrease application performance, so use it with caution. Default value is “NON-OPAQUE”.

Max LOD Hysteresis Interval

The length of the interval (in meters) used for switching LOD levels. The half of this value is added/subtracted from the distance threshold in order to make two different thresholds for switching to the lower and to the higher LOD level. This should reduce LOD “popping” effect. Set to 4.0 by default.

### Object Selection¶

Object selection settings. Objects can be selected both with the API function pick_object() and with the logic nodes.

Note

In the scene viewer, selection is enabled by default. You can turn it off in the Tools & Debug panel.

Enable
The parameter that defines if the object can or can’t be selected. It can have ON, OFF or AUTO value. Set to AUTO by default.

### Anchors¶

Anchor visibility detection settings.

Detect Anchors Visibility
Anchor visibility detection parameter. Can have ON, OFF or AUTO value. Set to AUTO by default.

### Export Options¶
