SceneCapture2D capturing different scene than player camera

SceneCapture2D inherits the same PostProcessVolume settings as the player camera because the camera is positioned within the PostProcessVolume.

Mucking with the gamma I can definitely get it closer but it’s not precisely identical. Is there something else specific to rendering to a texture that’s different from rendering to the main viewport? Are there other global output settings? And where do I find the the “target gamma” for the main viewport?

Thanks!
