I've built a Post-shader which takes a rendertexture rendered by a second camera, and overlays this texture (rendering only a certain layer) on the Main camera's Scene Color, after some blurring etc. Now, after having gotten it to work, the Scene Color node renders nothing but black.
What went wrong? I am using Unity 5.6.0f3 and Shader Forge v1.36.
(for shits and giggles I used the Scene UV's as a substitute, and it works)
My main camera is using the classic Graphics.Blit(source, destination, effect); line OnRenderImage.
