The only cel work I've seen is in the tutorial section. What's been your esperiences with this? Have you seen any? How does it work on instanced (ecosystem) objects?

Since I wrote that tutorial, I may as well try to answer your questions :) I have a few cel-shaded images in project. I am stumbling on a major limitation of the cel-shading as explained in the tutorial... so right now, I am pretty much stuck. The cel-shading effect in the tutorial relies on the 'incident angle' to trace the outline of an object. This works reasonably well for smooth, curved objects. It does not work on sharp edges, such as a cube. For that, we would need a parameter such as 'local curvature' or maybe 'local angle between two edges of a polygon'. To answer your second question, the effect in the tutorial works well with ecosystems. The flowers in the final scene with the 'bunny' are generated with an ecosystem.

and that would make a cool workshop theme, I think, although it would only be open to Infinite users, which may not be nice!

Actually, there's a python script in Vue 4 Pro that can help with a cartoon effect. I've been trying to get some interest from folks who are good at scripting to write something for Infinite. I've done some pseudo-cell shaded stuff but needed to use Photoshop on the Vue renders, and they still didn't turn out quite as I wanted.

I've used Agiels Cel-tutorial on several renders. In fact I have tweaked it quite a bit and made it one of the skin shading options for SkinVue by combining it with my procedural skin mat. The outlines often do need a bit of photoshop tweaking however.
