As to the code, It's not that much different from the stair command sample so I don't feel too much attachement to it. Anyway, I have kept some notes on gotchas I've run into. Currently there's not link for it on my web site but it's there. http://www3.telus.net/robbert/zekaric/devNotes/notes.html It might also help if you are going to start a plugin yourself just so you don't run into the same roadblocks that I've already smashed into. Just to note, I'm just starting off as well. :) A lot to learn so the notes aren't all that complete or extensive. Carrara SDK Yahoogroup is the place to be for plugin discussion. All the mysteries of the magic eight ball will be revealed there. :)
