Hello! And welcome to our forum!

Could you show the log from the web browser console?

Hello Alexander,

The problem come from the audio setting and the physic from the character

Thank you for the report!
This is definitely a bug. We will investigate it.

Could you apply the following patch and check whether the crash still exists?

diff –git a/src/intern/camera.js b/src/intern/camera.js
index 0d34606..a9a27f8 100644

Where schould I apply the patch?


I'm really sorry I'm not the best with programmation.
Thanks for your help !!!

1) The patch should be applied to the src/intern/camera.js
2) Find the function get_camera_angles_from_quat
3) Insert two lines tagged with "+" between

and

but do not copy these two "+"

Or use more correct way: patch or git apply commands

thank you very much !!!!!!
They are no problem any more, it's working perfectly !

Hello Alexander, if I export the project with Project Manager, the problem come back again . Do you have any idee ?

I suppose you should rebuild the engine.
On MacOS or Linux open your terminal in the blend4web directory:

make compile_b4w
