shaders tutorial?

I'm a noob when it comes to shaders. Does anyone know of a good step by step tutorial for creating a .shader file for a player model?

It depends on what you're planning to achieve. A basic shader is simple enough to guide you through this forum. For a start I think it's okay to tell you how to get the most basic shader going right here.
But I need to know what are you looking for first.
About tutorials, I don't know about good tutorials, didn't search neither.

Well, I'm trying to create hair using shaders. Similar to the Wookiee model. I just need to make it 2-sided and alpha out the ends.

Hmm... I tried coping and pasting the "legfur" lines from the wookiee.shader file and renaming whatever needed to be renamed. It seems to work ok but for some reason I can see my saber through it Also the transpanency edges aren't as sharp as I would like... Maybe it's just my crappy videocard.

I would try it over a searchengine. Since JO based on the Q3 engine there have to be some tutorials related to Q3...
they should also work for JO shaders.

yeah, I tried that. The only thing I found was a Quake III shader manual at:
http://www.heppler.com/shader/
while it is very helpful, it's a little hard to understand... I'm still having problems with the lightsaber showing right through the model. Its driving me insane

Shader Manuals

You can download, read or print the shaders bible from www.qeradiant.com. You can also download the SoF2 sdk and read/print the shader manual from there, cuz it includes the changes made by Raven to the shaders system.
I suggest you to read it, try to understand the concepts and every feature (at least the ones you find usefull) and then experiment for a while.
It's pretty amazing the efx you can achieve by combining several stages with different efxs.

models/players/meryl/hair
{
{
map models/players/meryl/hair
blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
rgbGen lightingDiffuse
}
}


I think this was the line I used. I'm not too sure though.
