Hey, the code in your custom pass looks fine to me. Can you inspect the individual render textures in your UI to check if they have any transparency in them or color bleeding from another camera?

The render textures are being generated at runtime using new RenderTexture(pSizeX, pSizeY, 16), is there something i'd have to do to ensure they have no transparency?

I will note that the image showing through is not what's directly behind in the game view, it's from somewhere else on the screen
