Artist project - Extracting avatars from Second Life

Hi there

I am a London based artist attempting to extract and 3d print Second Life avatars, but have little technical know-how.

I have been told that blender works.

If anyone can offer further insight into the software or perhaps could offer some help with rendering from images that would be greatly appreciated. The avatars will be featuring as part of a large exhibition in Scotland later this year, so expect some credit!
