Hi , I want to make PostProcessingEffect(Bloom) in Oculus GO , but it's difficullt. So I want someone's help.
My environment => Unity2019.1 + SinglePathStereoRendering + ForwardRendering
I tried to make it by self using Graphics.Blit() or CommandBuffer.Blit() ,however the one was broken drawing and another was no change in Oculus GO( on PC ,it's changing).
I found some bug reports about Graphics.Blit().
I don't know the reason why no change using CommandBuffer.Blit() in Oculus Go.
I show the easy test code of CommandBuffer (this code is same status)here , so please help.
----------
P.S
I find this , but my problem happens on 2019.2.5f
