-==Introduction==
-Postprocess effects are a common type of effect, typically applied as a full screen overlay.  In the Source engine, this is achieved by rendering a full screen quad with a material that either contains an animated texture to blend with the screen, as with blood spattes, or a custom shader that reads from a framebuffer texture, usually __rt_fullframeFB.  This techique is used to create a number of different graphical effects, from film grain or color correction to image based edge highlighting and certain types of toon shading.
-This tutorial will cover all of the aspects of setting up and running a postprocess effect with a custom shader.  The information can also be used to apply full screen textures using built-in shaders such as [[UnlitGeneric]].  For more information on creating custom shaders, see [[Shader Authoring]].  Episode one engine is also assumed, since as of this writing it is the only engine version to support custom shaders.
