Render Custom Depth coloured rest everything greyscale

Development Rendering

I want my custom render actor to be present in colored and rest everything in game to be in grey scale.

I have never used postprocessing so this is what I have made until now…

The custom actors appears to be white without any color. What should I change?

Instead of using SceneTexture.SceneColor you might want to use SceneTexture.PostProcessInput0

SceneTexture.PostProcessInput0 what does that do?
