Need Shader Help

I've been messing around with shaders and I've read many tutorials but I still haven't come to grips with shaders.

 

I'm looking to make a leather shader for one of my projects and was wondering if someone would be willing to help me out. Either PM me, e-mail me , or reply here if you're able to lend a helping hand. Any help would be greatly appreciated.

Ok, you'll need an alpha channel on your skin.

What I'd recommend (if the leather you are looking for is going to be black)

Make a separate layer over your texture, then use the polygonal lasso tool (or whatever you prefer) and select all of the areas that you want to have the shader affect. Fill this with a light color (maybe white, depends on how much you want it to shine). Invert the selection and fill that with black.

Create a new layer (multiply-overlay-or soft light) fill it with 50% gray, then a 15% noise. Blur this and adjust transparency until you have a noticeable texture/mottling on the light areas.

Flatten, invert, and use as your alpha channel.

 

In Q3ASE

 

Layer 1- skin texture (lighting diffused)

 

Layer 2- Env Map (lighting diffused) additive blendfunc

 

Layer 3- skin texture (lighting diffused) blend blendfunc

NOTE- if appearance is wrong, either invert the alpha channel in the skin, ,or customize the blendfunc and invert the alpha represented.

It's easier imo to use PSP to get the alpha channel in there.

Check the help file for PS or PSP. I'm sure it would be in there somewhere. Just make sure to keep a copy of the orig texture before you flatten the image with the alpha channel.
