Yeah, no need for suggestions. However the builder's forum would be a great place to pick up where I left off (for me at least).
As for poly trimming, I'm good at that (Normal maps ftw). What I've been using is the Unity3D Engine... Of course I'm just starting with it, but I've actually figured out a couple of things already. Anyways, a lot of models should not exceed 10,000 polys (Never exceed 25,000 polys on the Unity Engine... Never). I stick with the "no more than 5000" rule. I did a simple 2000 poly character with normal maps and it looks very good (However I noticed that my normal map is inverted in Unity --- Link of video down there... I was testing stuff). I dunno what Second Life's Engine can handle (I guess call it the Linden Engine, heheh), but if it's anything like the Unity Engine, I bet it can't handle much anything bigger than 10,000 polys efficiently. I'm sure they'll figure it out eventually.
Anyways, onto my 3D Model building, I should get Taichi in there X3 My greatest accomplishment since I did so well on the first animation with him X3 (Actually... Today's Saturday... I'm gonna do something outside, lol; then I'll work on importing Taichi)
