Since I started this thread as Fun with Textures,have to admit I am having fun :D

I created the dress so I could have one dress that would work for most uses.

When (or if) I release the dress, I have it set up so you only need to load the basic color map, the trans map (if you want something different, the trim mask, and the color of the trim.  adding a bump map is easy 

I will include at least three basic patterns If I release

because of the low comment to  view ratio, I thought it needed to be simple

Bump maps are easy, and spec maps need to be multipiied by the trans map

Fill

People that know everything by definition can not learn anything
