Setting hlsl buffer value from c# code?

Hello, I've been working on porting a 3rd party image effect hlsl shader to Unity and I have a buffer to set for the shader to work correctly. Buffer _bSamplePattern : register(t2); My question is, is there any way to set the `Buffer` of the instanced material in the c# code or I have to rewrite the buffer thing into something else? Thanks, Raul MadGoat Studio
