In my WebGL browser app, i've tried to add Post Processing (first version) stack.

I'm using Unity 2018.4.6f1 (i started 1 years ago to develop this app).

I've added Post Processing Behaviour to my Camera, and this is what i've enabled:

enter image description here

When i run my scene on Chrome or Firefox, Camera appears all black but UI is correctly rendered.

Are there any incompatibility issue using Post Processing and WebGL ?

    \$\begingroup\$ Did you try enabling just one effect at a time, to work out whether it's specific effects that don't work, or all of them? Before activating the post processing stack, were you using HDR or deferred rendering? Some of these post processing options might be forcing the rendering to use those paths or something equivalent. \$\endgroup\$

PPS is not supported on WebGL 1. You should have Webgl2 capable browser and GPU required to run WEBGL 2. You can test here or this for WEBGL2 support on your browser. Fore more read this post.
