Clear Flags Effect - Image Effect to reproduce the Clear Flags camera effect. ... Distortion is ideal for creating heat haze effects for fire, for example: This effect can be quite expensive because it captures the current frame to a texture. Inside your SubShader tag, add the GrabPass syntax to grab the screen behind the object and put the data in _BackgroundTexture: Make sure to add _BackgroundTexture inside the CG code also: Now, let’s extend our vertex shader to output the screen texture grab position and extend our fragment shader to sample the background texture (instead of outputting a plain white value). A perfect way to simulate caustics for example. All the scripts and shaders used in this post will be available at the end of the article, but to start with, I’ve uploaded a unity project with a scene set up with this effect ready to go so that it’s easy to follow along here.
