I want to render things with clay.inc on the body parts, and acidbath on the joints excluding the head. can anyone help me out? or tell me how to exclude and include different inc's to different parts of the render?

example of what i mean:


{
#include "clay.inc"
#exclude "glossy.inc"
Head

Hands
...etc
}
#end

{
#include "glossy.inc"
#exclude "clay.inc"
Joints
}
#end

any help would be nice.
