1 VR camera uses 6 RenderTextures ?

Hi,

I'm trying to optimize memory use of my app running on Quest.

I noticed that my scene allocates, according to the MemoryProfiler, 6 RenderTextures.
That seems a bit excessive to me. I would understand 4, 2 per swap-chain per eye.

Are 6 RenderTextures expected?
This is using Unity 2018.4 and multi-pass stereo rendering (single-pass is not an option for other reasons)

Thanks.

 

It depends on the pipeline and options and any post and if forward or deferred and so forth I guess. Without knowing more... dunno.

 

So, in my case there is no post process, no shadows and a forward render path, using multi-pass stereo.
Thanks for looking.
