In the forum, I found the post related to anti aliasing of Web VR, and used the script FXAA
After using fxaa script, enter the VR phone black screen.
Debugging using the old version (v1.31.0) source code is no problem.
And if the computer enters the project, whether it is the new version or the old version of the code will shake
Hi @sixeco_z,
I remember I had problems in the past running post process effects with a VR camera.
For anti-alias, just to be sure, do you have device pixel ratio enabled? Do you still get pixelated edges with that on your headset?
Device pixel ratio enabled
For the FXAA effect not working, try posting a github issue request on the engine repo.
Most likely something is different with the way VR camera is treating the render targets and breaks the effect.
Well, it’s not that it doesn’t work. It’s the latest version that’s directly black
No one wants to solve it?

Once we get that, we can create an issue on GitHub and have someone on the team try to take a look at it.
I’ve tried reproducing the FXAA bug here with no luck: https://playcanvas.com/editor/scene/962288
Is there something I’m missing in this scene that you have in yours?

No difference was seen
