Hi! As mentioned above, is there any way to use output color from first pass fragment shader in second pass? I would be grateful! )))))

Depends what you want to do with it… but not without GrabPass - which is Pro only.

If it’s very simple maths - like multiply by a value or add a value, then the blending modes will let you do that.

I want to use output fragment color from first pass to offset UVs coordinates in second pass depends on rgb values…

Yeah, you’ll need to use a GrabPass then. Which requires Pro render textures.

Why do you need two passes?
