Gameplay Camera System PostProcess Feature not support material

I make a test following step:

  1. Add a Gameplay Camera component to Character and set component automatic activate for player0.
  2. Setup Gameplay Camera System follow the step by official tutorial.
  3. Add a “Post Process” Node in CameraAsset Rigs Graph.
  4. Add a easy PostProcess Material to “Post Process” Node ( The easy Material output emissive=0.3 * ScenceTexture:PostProcess0 color) .
  5. change the settings of “Post Process” Node : Temperature=150000.
  6. run game to test.

expect result:

  1. PostProcess Material should work, the scene should have darker color.
  2. Temperature=150000 showuld work, the scene should have warmer color.

test result:

  1. PostProcess Material not work, PostProcess Material has no effect.
  2. Temperature=150000 worked, it has effect warmer color.

FeatureRequest:

  1. We want CameraAsset “Post Process” Node should support Post Process Material
  2. We want have some way to obtain the Gameplay Camera Post Process reference in blueprint, since we want to change post process material parameter in game runtime
  3. Gameplay Camera should support Orthogonal Mode not only Perspective, I can’t find where to change it.

Confirming this bug, afaik post process materials do not work with GCS in UE 5.5
