Not sure this can go here, seeing as it doesn't pertain completely to Halo, but...
I am horrid at making skins...
mainly I go to a website I know of and take the textures, and make them tile.
I've tried following ScottyGEE's tut on tiling correctly too, and I can't get into the part where he makes a stamp, because I can't figure it out on Photoshop CS2.
Mainly though, I wanted to know how the heck to make my own textures completely...
If you can help, please reply or PM.
