Yeah, of all the things I missed about LW was it's "dumb" edge and line mode- that really wasn't so good for making NPR on it's own, but great for fiddling with. They were blazing fast- that helps a lot. That and the way the motion blur worked with sub frame animation. Again, not the kind of blur you want to use for most animation- but for this purpose it was perfect.
I've been too busy on a project to fiddle around with this, and do a few mini-tutorials (like just sampling the BG for "BG GI" etc.)- lots of cool new things to try and jack in modo though so I look forward to when I get some down time.
I figure between you, david maas, and I we should be able to see what can be done in Modo in terms of NPR hack'n though! Looks like a lot of people are getting good results just using the tools straight up- but nothing really sketchy or painterly yet- getting closer though eh?
Looking forward to your shaders BTW Thomas. In your free time, if you come up with a node system that fits in the layer system of Modo I'll be first in line to buy! I can dream right?
