Ssr postprocess ignore rtt's setMaterialForRendering for mesh

PG: Babylon.js Playground
I set a red material for the ground in rtt, it works fine until I add the SSRPostProcess.
I also tested with blurpostprocess but it works fine.
Actually I doubt it a bug because ssr don’t use the setMaterialForRendering while rendering the prepass_color texture.
So how can I make it with ssr?

I’m having a bit of difficulty to understand your scenario You created a RTT, but isn’t displaying it anywhere. What are we supposed to be seeing here?

You can see the rtt in the inspector, and I thought the ground should be red in the rtt because I use setMaterialForRendering, but it shows the default color in the rtt.

Hi !

I guess this is linked with this issue:

Issue when PrePassRenderer and RenderTargetTexture are used at the same time

Hello, I’m new here and I don’t really know if my problem is due to a bug or a misunderstanding on my part. I’m trying to create a new PostProcess using both renderTargetTexture and PrePassRenderer. However, when I use both of them, my renderTargetTexture display the base texture of the scene instead of the the ShaderMaterial result (as if the RendertargetTexture was replaced by something else…) I didn’t manage to exactly reproduce the problem since I didn’t find how to set the configuration …

When I use GBuffer instead of using PrePass in the SSR parameters, it seems to work.
