Blend4web never appears on the "Add-ons" tab

Hello, I am new to Blend4web and very interested in getting it working on my Windows 7 system. I have followed the instructions and viewed several videos, but Blend4web never appears on the Add-ons tab so I can't activate it.

I have tried:

-Uninstalling/reinstalling Blender 27.8c.
-Uninstalling/Reinstalling Blend4web.
-Downloading Blend4web three times in case there was a problem with the file.

The "blend4web_ce folder" is in the "C:\Users\Jim\AppData\Roaming\Blender Foundation\Blender\2.78\scripts\addons" directory, which I believe is the correct place. Blender is correctly seeing other add-ons which are in that same folder, so whatever paths are set up in Blender appear to be right.

I used the Blender Windows installer so Blender is in the default C:\Program Files\Blender Foundation.

In case it matters, Blender froze every time I selected "Install from File" so it's possible some essential file did not get moved into the blend4web_ce directory, but the folder has gigs of information so it seems to have unpacked correctly. I also tried manually unzipping blend4web_ce and copying it into the \AppData… directory but it still doesn't appear as an add-on within blender itself.

I of course rebooted my Win 7 system and made sure there was plenty of memory and hard drive space.

Any suggestions? I notice that the other add on has a __init__ python file, but the blend4web_ce folder does not. Is there some way to force Blender to activate it besides the checkbox in the UI?

I tried today on a second Win 7 computer and had exactly the same behavior. Blender freezes when I click "Install from File." Strange.

Hi! And welcome to our forum!

Installation of Blend4Web SDK is a bit different from addon installation.
Did you follow the installation instruction from our documentation?


Here is copy-paste from the doc:

• Run Blender.
• Open the User Preferences panel File > User Preferences….
• Open the File tab.
• Set the path to the SDK directory in the Scripts field.
• Click the Save User Settings button.
• Restart Blender.
• Once again, open the User Preferences panel File > User Preferences….
• Open the Add-ons tab.
• Enable the Blend4Web add-on.
• Once again, click the Save User Settings button.

Thanks! I didn't realize that I had to point the Scripts path one directory deeper to the SDK directory. Changing the scripts path did the trick.

i have similar problems with finding blend4web addon,… i have scripts set to blend4web_ce_17_10_1/blend4web_ce/scripts/blender/

this gives me some more addons to choose from on addons tab, but not blend4web addon specifically.. whats me doin wrong?

Hello! And welcome to our forum!

You should set scripts to blend4web_ce_17_10_1/blend4web_ce
