Bugs

Hi,
i just updated to babylon v8.20 (from 7.10, because we had some breaking issues that i am going through).

Currently on chrome I am getting an error on the following line:

chunk-2NBTPGO4.js?v=e80c8ec5:76 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'postProcessManager')

It is hard to follow the error. The Texture is called “data:EnvironmentBRDFTexture0” same as url.
I am also using react-babylonjs.
Somewhere I also read about tree-shaking. But not sure if this is the issue.

Hope someone can help. I dont know why the texture is even created.

ahhh … bug on our side with a regression. the webgl context was lost on unmounting of a react component.
