change culling on a material basis

Hi there,

I'm wondering if there is a way to reuse one cg shader for different materials? I'm looking for a solution like in ogre where you have your material and just link the shader you want to use. In unity the material and the shader is somewhat the same but maybe there is a trick to achieve the same?

multi_compile goes into this direction but is bound to the cg code block. #include is also helpful but does not allow to include a complete shader with pixel and fragment part.

Anyone knows something more in depth?

 

By shader I'm talking about everything inside the CGPROGRAM section. Everything else is the "material" in my sense.

And redundancy is preventing me from creating several copys of the same shader in different materials. The shader should be in one master file and just be linked into different materials OR writing a master shader/material which is compiled to all permutations by unity itself.

 

to answer my own question I highly recommend the following link:
