I probably didn't explain it very well. My multichannel mixer has one multichannel with lumber settings and another multichannel with noise settings.(This is a simplification. They have lots more besides. I am trying to make a realistic procedural wood shader) The blender is a simple value to balance the two multichannels. I am looking for a way to scale the entire shader. This way I could easily use it on different objects. Any clearer? Thanks for taking the time to decipher it!
