Questions about texture templates and Second Life

[gaogao]

Hi, I'm really new to AC3D. I've made a few models, now and would like to know if I need to add triangles in order to make it work in Second Life.

Also, I am puzzled as to how I should come up with a texture template for my models, for example:



Bottom right had side is a template, I am guess there's a program that will take the data from my models and make them into a template? I don't know.

Thanks
