more like, open source as it should have been. imagine what kind of modeller maya could be these days if that thing had spread like certain poly-scripts for max did back in the day. christ...
I second the glue-sniffing comment. It might be nice, but is it 300$ nicer than Roadkill? Or for that matter, other programs' built-in tools or scripts, now that even max has pelt-mapping, and Silo's unwrapping-tools have grown up a bit more?
The pinning feature looks pretty nice. Everything else which I need, I can already do in Maya or Max. I might look into writing a plugin or scripting something like that for Maya, seems like it should be possible.
It's packing ability looks interesting but not $300 worth of interest. And no Max and Maya's UV tools do not suck. The problem I see is that people don't take the time to learn them and rush for scripts or 3rd party apps assuming that if its part of the core package it has to be bloatware.
