Somewhat related: I wish there was an easy way to render a character's line work as a separate render pass from Moho.
For example, maybe set up a Moho Layer Comp with a 'Strokes Only' option eanbled, so when I use Moho Exporter to break out my layer passes, it will render the special layer comp that has 'Strokes Only' enabled. The tricky part, of course, is making fills transparent but masking any lines that exist behind the fills.
I can sort of do this now using a setup involving reference layers, custom styles, and maybe smart bones, but that's more complicated than it should be. A simple "Strokes Only, Please, For This Layer Comp Setting" button would be so nice.
Right now, I'm basically rendering the 'Stokes-Only' pass with solid white fills and black strokes, and using Multiply in my compositing program. Not exactly the same as having a transparent fill region but it works too. When I'm in a real hurry, I may simply key out the linework but that's not an ideal technique. (This latter technique is easier if you render without anti-aliasing, and use the free
OLM tools to key out the strokes using OLM Keyer and
then add AA using OLM Smoother.)
Anyway, the 'Strokes Only' option would be very helpful during compositing when I need to light a character as a post effect (a very common need,) and hold out the character's line work so it's not affected by the lighting technique. Then I can just bring it in as a proper layer, with no special post-process tricks needed.
