Someone asked about how to install the plugins. There's a pdf file included with the plugins (or at least it should be) that has official instructions. Also, the 3ds max plugins work with versions 6, 7 and 8. 8 is the last version to work, newer ones don't.
The ones in the SDK are a bit confusing, so I plan to add a simplified copy of the instructions here.
As for the 3DS Max plugins, that's good to know. The installation instructions should be the same for all three. c:
