I am trying to write a composite Image Effect shader with a script that works as such:
The camera texture is taken, and stored into two different variables. For examples sake they will be tex1 and tex2.
tex1 is modified by a shader.
Both tex1 and tex2 are taken into another shader, which composes them together. The result is stored as tex.
tex is printed to the screen.
I am not having an issue with the actual content of the shader manipulating the image-- But I do not know how to pass in both textures to one shader as needs to be done in step three. Thanks in advance if anyone can help.
