Thanks for the plug Claudia!
Can you guess who pushed me for these features? ;-)
One more thing to add- when doing painting type applications with
SMC, you can blend the edges between regions- another thing that
shading domains is not really suited for. Also, you do not have to
use a vertex object, it works just as well on a spline or primitive.
