So for those of you using maya on your projects here just wanted to let you know there is a Auto Unwrap tool made by autodesk, I did not know of the tool (probably did not read enough) but I am sure some others do not either but its free and you can grab it here
http://area.autodesk.com/bonus_tools will need an autodesk id but you can sign up for a free one in about 30 seconds time with no email verification. The best thing with this tool is you can define where it unwraps with boarders or anchor points, and you have both manual and auto ways to add them. It even will auto follow curve boarders and unwrap curve items to see a demonstration of the tool head here (not my video) [video=youtube]https://www.youtube.com/watch?v=UyhwoZTrB_s[/video] https://www.youtube.com/watch?v=UyhwoZTrB_s
it is super quick to use so can be a life saver for fast and rapid model production.
