thanks aen,firstly
My question is not the means that your said, maybe my
expression isn't right.
I use the toon shader in my scene. generally, an attr of toon shaders
be connnected automatically to rendering camera' message attr. Now my
scene have 20 cameras to be render, and I can render all cameras in
one time by useing a plug-ins. So I have to setup the connection
automatically between toonshader'attr and camera' message in my mel
proc when rendering different cameras, and then I put my mel proc in
" Pre render MEL" on Render Options. I think , I must get the
camera' name that being rendering, then make the connection in my mel
proc.
I don't know that U understand my meaning?
thx
kelvin
