If Contour Shaders prove to be unusable, I will have a look at that stuff, but the examples in that paper don't look too motivating to me.
The Tomcat shader may use some basic principles from this technique to find the contours, but it uses maya paint effects for its great looking strokes and styles AFAIK, something that isn't available anywhere else.
But Hair placed along contours may be a funny idea to try... :-)
I know a lot of other NPR workarounds and techniques, like cloning your model, make it all black, render/show only backside polys and use a push op (or displacement) to set your line thickness. Visible in the viewport too and renders reliably with almost no overhead since it isn't based on subsampling. Combined with weightmaps for the push or displacement maps, you have very fine control over the "strokes".
...and sure it has problems too like all options I have evaluated so far... ;-)
But for this particular job, I just need simple Flash-compatible ink lines in one color over extremely simple objects for animated symbols and waiting half an hour for 25 frames at 350 pixels square isn't practical when Lightwave can do it with better quality in seconds.
Well, I look forward to try the MR contours with Halfdans help.
I will let you know if I come up with something usable.
guillaume: I don't know what happened exactly, but Toon shading was the only "unusual" thing in the project, so I assumed it to be the cause for the crashing and massive buggyness. Sure I can be wrong and it was goblins... ;-)
Does the old Swift 3D for XSI still work in 5.11? Maybe I can find an old license somewhere on ebay?
Kim: Does your "Swuff" still work for 5.11? Is it available somewhere? All links I found are dead.
Thanks for all the input!
