At one time I had a PDF or two that explained how to actually do something with Fenric's ERC -- but I can't find it and the forum search just found lots of hits in the commons so...
What I'm looking for is a pointer to PDF documentation or pointers on how to do what I want (or that I'm doing it wrong, or can't be done, whatever).
At least, I think what I'm after can be done with ERC... what I want to do is add a slider -- don't really care where -- that directly controls a value in a shader (actually, one slider that controls a value in multiple shaders). The description says you can drive any animatable parameter and the one I'm after controlling is in the shader room. One issue would be that the fenric menu is not available while in the shader room... But even outside of that I can't make anything *happen* in the assembly room. To tie things together there has to be an interface *somewhere*.
