I built a simple test scene with a few cubes and added SSAO to the camera and it worked fine in the WebGL-build.
Now I tried to add SSAO to a camera (Unity’s standard first-person template) in one of our big pre-existing projects… and while working perfectly inside the editor it simply does not show up in the WebGL-build. I disabled all other image effects on the camera (like Bloom or AntiAliasing which btw all work fine in the build!) and I deactivated all other cameras in the scene… but still… NOTHING. SSAO just wouldn’t show up in the WebGL-build. Now the project is big and complex but there is nothing in there really that I could imagine causing this behaviour.
So does anyone of you by chance happen to know any cross-effects that might tinker with the SSAO Image Effect specifically? As I said, all the other Image Effects work fine which first led me to the assumption that the SSAO was broken… but the test scene proved otherwise.
