I'm using Blender to create some small (average size about 64x64 pixels) game sprites, and wanted to experiment a bit with cel-style shading. The shading itself works alright, but at that size, I wonder if it's possible to get a good sharp outline around the sprites' edges, or basically limit the thickness of the lines somehow. It might still pose some problems though, trying to arrange a pixel-perfect transparency mask. Usually just disabling oversampling gives a good solid border, but the outline seems like it would cause problems with this method. Maybe I'll have to do two separate renders.
render big then shink it down, perhaps that will fix the issue.
Turn OSA off, but also render using the Key setting (instead of Sky, in the Display Buttons window) with RGBA and a format with an alpha channel (like Targa or PNG). Then, you can create the transparency mask in your favorite painting program.
