I am working on a Altair Skin from Assassin's Creed, and i am almost done but one thing bothers me and i don't know how i can get rid of it. Look at the picture. I can't remove the thing under the chin.
a model was made, but never released
Well there's one in progress, and as much as I hate to say it, of far better quality.
Maybe you can help them out instead of re-skinning a model?
As for this, it needs a lot of work. If you'd like to persist with this one, I'll gather source material to help you out.
The main issue is..that's not a texture - that's a shaded image. There's no real definition of clothing, and that doesn't sell the appearance to the user. This can take a while to be good at, so I'm not going to bite your head off =p
As for that spot, try disabling each surface one-by-one in the .skin file by replacing the texture path with *off until that spot disappears, then you'll know which texture/shader to edit.
