Post-Processing Layer on Main Camera of '3D (with extras)' scene renders black in RenderStream layer #1
Description
Tested in Unity 2019.4.24f1, RenderStream 1.23, Designer 18.0.3.
To repro:
-Start a new Unity Project with the '3D (With Extras)' template. (this places Unity Post-process layer on the main camera.
-Build the Unity Project. Move the built project to d3's RenderStream Projects folder.
-Setup d3 with a RenderStream Layer, MR set mapped to main camera as per the README.
-Select your Unity RenderStream Asset and start the workload.
Result: Unity exe launches but the RenderStream content is fully black.
Expected: You should see the Unity 3D Scene with Extras scene content on your projection surface.
Workaround: Disable the Post-process layer component on Main Camera and rebuild, set your new Asset in d3, stop and start the workload. You will now see the scene. This implies that the Post-Process layer on Main Camera is introducing something bad into the RenderStream that d3 doesn't like.
