I had meant to post this up before GDC, but I was overloaded with deadlines leading up to the conference, unfortunately. For anyone who was at the conference, you may have seen that I was a guest presenter at the Autodesk booth twice to discuss the Maya <-> Unity workflow for iPhone development. These presentations were streamed live via their website, but I will post a link here later if they make them available somewhere. (EDIT: One of the presentations is now available online. Visit the Area website to catch my presentation.)
Moreover, Ryan and I recorded a Maya Python MasterClass for them, which you can view on the Area website. In it, Ryan covers an example of how to use threading and I cover an API example (the expose transform plug-in I recently released). Check it out and let us know what you think! Please note you will need to go through a free registration process on the Area website to view this video.
Autodesk put up one of the presentations that they recorded (the less good of the two, in my opinion), and I have included the link in the post above.
