Services. Foggy Window Shader. This requires sampling of the color buffer, like we're already sampling the depth buffer, but with the addition of a UV offset. output.grabPos = ComputeGrabScreenPos(output.pos); Hi Linden, thanks so much for this great tutorial. Here’s the final code for the distortion fire shader again, under a non-commercial open-source license.
