Not sure if there actually is one and I haven't yet reached it, but based on a quick search, I noticed CGCookie doesn't have any tutorials about working with vector graphics in Blender.
Obviously it's not going to help much for robust, realistic 3D modeling, but if you're making something like a cartoon-styled model, it can look good to have 2D decals for things like facial and/or clothing features. For a Lego Character, it's absolutely mandatory.
I know a lot of the 2D texturing is already covered in the Concept Art and Texturing courses, but what about utilizing it in Blender animation? Like how facial expressions change in the Lego Movies or the newer Pokemon Games? You could also maybe explain how to work with vector graphics in programs like Inkscape or Illustrator? I know of a Youtube tutorial that explains it pretty well, but I think it'd be cool to have a course here.
Hey John, it is possible to use vector graphics in Blender (definitely would be a cool addition when we do a course on curves - I'll add that to my notes), but I'm not sure that's what was used for the Lego movie, and I'm pretty confident that .svg files are never be used in games since they take up lots of memory and are difficult to compress.
Either way, the printers that print the lego figures in real life only have a limited resolution, so to be totally true to form it would be preferable to just use a high resolution image texture with a lot of facial expressions on it, and then animate the UV's to swap between the different parts. Does that help?
Sorry, I used terminology I didn't fully understand. When I said vector graphics, I was referring to the type of art that can optimally be made in Illustrator/Inkscape/Pen Tool (ie- simple facial decals), not necessarily .svg files. That said, it would still be cool to see what can be done with vector graphics in Blender.
Second paragraph is exactly what I was suggesting. Say you had a simple character where, instead of modeling all the facial features, you would have this .png image with a set of 25 different mouths and eyes which can be changed at any point while animating using a bone. I don't think there's a course or tutorial for that on this site, even though it's very useful for particular artstyles; lego being the obvious example.
