Toysoldier Thor has a blog post that went up a couple of weeks ago. I missed his email telling me about it, an overactive spam filter, until today. For those that are new to 3D modeling and texturing of models, Toy’s article is a good starting place. Check out the 8+ minute video for a quick overview.
Toy’s blog has more information in a post: My Experiments with New SecondLife® Materials System. If you are new to this, it is worth your time to read the article and watch the video. The video is somewhat a quick summary of the blog post.
