Well looking around it seems like its a file format specificlly for Ray Dream Studio 5 so unless someone around here has already paid for it then I guess that idea is shot. So I guess the next question is where is a good site for 3-d models? Paricularly if they have robotic/mech models.
edit: what about .max files? Found
http://www.3dm3.com/modelsbank/model385.htm
but I am wary of just trying different programs without knowing if they'll help convert the 3d files.
edit2: Found a .3ds file of a few different downloads and one gave me an error (this is after I converted using biturn) and the other had no texture (in the pic it appeared to have a texture but not altogether sure). Can you tell me about the whole converting deal or link me to a topic that has the info?
