Texture Rendermap Issue.

[Epifire]

I have constantly had texture errors when sending other models to people. I also use modtools 6.0 so I cannot format to tga myself. Now I had the idea of making one whole UV map out of the entire texture selection so that I would avoid all errors.

That should help a bit cause I allways like to let people know what I am talking about. 

Ok so you see I have hit Property/RenderMap, to get to this menu. I can do most else except for the X resolution, cause when ever I test different scales my PC can't handle that. So what do I do for it to come out right?
