Hello everyone! I am currently dipping my toe in texturing units for a game called Mount and Blade. I am trying to make folds and little wrinkles in the clothes look nice, but I can't seem to really do it! The following two images show what I have so far (Please note I know its not perfect, again im just sort of trying it out) and the second image is of a texture from the games with folds and wrinkles similar to what I would like. Any help would be much appreciated! Thanks -Watspoon
