Hi everyone! I'm pretty much a newbie. And I'm gonna sound like one for sure. XD; Anyhow, I'm trying to learn how to create meshes for Second Life, and...it isn't going too well. :\ I've tried experimenting with Second Life on my own, and hesitate to actually upload anything I make, because I can't test anything before I spend my money on it (or that's the way it seems...I'm sure I'm just doing something wrong here, and don't know what.) But anyway, I'm not really looking for anyone to tell me how to develop, I'm just looking to see if there are any good books, online written tutorials or video tutorials on Blender-to-Second-Life meshing. I already have Avastar, so tutorials for it would be great too. :) I can actually figure out how to mesh and UV map just fine, I'm just uncertain about rigging things to the avatar, exporting, sizing issues, etc for Blender, and then importing, adding textures, and testing, etc in Second Life. Just need a bit of a booster to get me going here. XD Thanks so much in advance! -Calbhach
