Specific Wrinkles

[Isick]

Ok so it is no secret that I am into texturing (AKA skinning) for games. Recently I have been focusing on honing my skills to get a more realistic look out of my models and their textures. One aspect in particular I am trying to improve is the way I create wrinkles, and there is a specific type I am working on.

I have the standard cloth wrinkle down pat - no problems, but something I can't seem to grasp is the wrinkle made when a thicker material is stretched and bent. This is found a lot when a Kevlar vest is strapped down or when a kneepad strap bends. It seems like a subtle difference, and it is, but it has just been bothering me.
Here are some examples I have found of what I mean:

^ in his upper leg area

^ to the right side of the knee pad where it meets the strap.

What I need help with is a method that will create them relatively fast and simply (I have so far used the Dodge and Burn and done it by hand, is there a better way?) and also how I know which direction to make the wrinkles. Standard cloth wrinkles generally follow gravity in the way the fall, but these seem to act different.

If anyone has any insights into how this is done most effectively please leave a comment. If you are amazed with my ability to tell my entire life story before getting to the actual question you may also leave a comment.

Thanks a bunch!

That was one great crotch shot.

Oh, and I have no clue, I'm simply here for the comic relief.

well an old method I've been using is to create a new layer, set it to multiply mode, use a hard edged brush with a close to white colour and make a layer style. Tick off Bevel and Emboss, and select the direction to down, and then the direction of where you want the light to appear from.
I mostly use this for cracks in stone or dents in wood, not sure if it'll work with cloth. I think it might though.
Try it if you like

There are many tutorials on how to draw folds and how they work.



Most of them are rubbish.
I do have a personal favourite though.

Excrutiating, I have used that for cracks also, but it never occurred to me to use for folds - I will try it out.

Yeah I guess the problem lies more in what direction to make them flow rather than how to draw them. That tutorial you posted Etheryte was very helpful.

I think I have enough here to work with, thanks.
