I have the same question as jumper.
The help “Transitioning between VEX and RSL” give some useful informatin, but it doesn't mention the Du(t) , Du(s) transition to vex. I tried to set the Shading Derivative VOP 's input to s for Du(s), but it seemed not right.
Does anybody give some directions?
thanks.
