Me too. I imported old work from Softimage|3D only to discover that despite the abundance of new features by comparison, XSI's toon shading couldn't produce the same look. Now I have to re-light my scene. :(
Specific differences between SI3D and XSI toon shading: 1. SI3D toon shading followed a phong shading model to place highlights and shadows (specular, diffuse, ambient). XSI draws the lines between these boundaries differently. To match the look you must manually specify the thresholds per material. Even when you match the look from a particular camera angle, everything is ruined when the subject, camera, or light moves. 2. SI3D toon shading had the option to make the ink lines the same color as the material's ambient color. In XSI you must use the override feature and specify the ink color manually per shader. This creates additional nodes in the rendertree in the form of color share nodes to plug into the ambient (surface) and ink ports to ensure they stay in sync. 3. SI3D ink lines taper very nicely to a sharp point when the line is drawn because geometry folds back on itself (as opposed to a material or object boundary). XSI toon shaders don't do that quite as well. The distance threshold doesn't seem to respect the values well either. That's not to say I don't like the XSI toon shading, as I was one of the primary beta testers of this tool back in the day. I just don't recall having these problems back then. Something changed over the years. The other irony is that the original scene was created overnight in SI3D, but it's taking me much longer than that to do it in XSI despite more tools, features, and much faster hardware at my disposal. Hmmmm. Matt Date: Fri, 16 Aug 2019 13:08:28 –0400 From: Sven Constable Subject: RE: Friday Flashback #382 To: "Official Softimage Users Mailing List. used the MR toon shading just yesterday.
