Support for postprocessing in VR?

[paavanb]

Hi! I've been having a great time working with this library recently, but I have hit a wall when it comes to postprocessing. It seems like using @react-three/postprocessing doesn't work when entering VR mode, causing nothing to appear. I'm not sure what I'm missing: I took the same scene used by #78 , swapped out ARCanvas for VRCanvas, and was able to confirm that nothing renders in VR (though once you exit VR, you can see what you should have seen). If you delete the EffectComposer, the scene reappears.

Any idea what might be going wrong? Perhaps some props that I'm forgetting to set?

My understanding is that THREEs EffectsComposer doesn't work in WebXR. The short answer is performance.

mrdoob/three.js#18846

That doesn't mean you can't do it. You just can't do it with EffectsComposer

Thanks for the explanation!

Best to continue this at https://github.com/pmndrs/postprocessing which react-three/postprocessing depends on.

That's infinitely more optimized than three's workflow and I've gotten it to work in VR beforehand:
