SET SCREEN EFFECT This command will use the specified effect shader and apply it to a built-in screen quad that will replace the default contents from the backbuffer.
Syntax
    SET SCREEN EFFECT Effect Number
Parameters
    Effect Number
Integer The effect number
Returns
This command does not return a value.
Description
This command is typically used in tandem with other commands that redirect backbuffer rendering to an off-screen camera and subsequently rendered to an image for post process shading. You can create an effect using the LOAD EFFECT command. This command depends on the QUAD.FX file located in the Compiler\Effects folder of the compiler, and can be used as a base from which to make modifications to your post process shader effect.
Example Code
    SET CAMERA TO IMAGE 0,123,640,480

    LOAD EFFECT "quad.fx",1,0

    SET SCREEN EFFECT 1

    TEXTURE SCREEN 123

    WAIT KEY
