any 1 how know a good shader tourial?:confused:

Just have a look round on www.google.com) there should be loads

There's a shader manual that comes with GtkRadiant. I know a lot of beginners hate it when they're pointed to it but when you make an effort to learn it and try to make some shaders on your own you can become a very powerful mapper;)

Just study the original Raven shaders (or any shaders shipped with your favorite custom maps) and if you are in doubt what some function might be doing, check it out here:

There arent any. That's because "shaders" is an incredibly expansive topic. Your best approach is to ask a question more specifically related to what you want your shader to do. From there, try finding a similar shader from the JA assets and look at its code. You can use the q3map2 shader manual (http://www.shaderlab.com/q3map2/shader_manual/) to look things up.

thats exactly what i do
if i cant find one similar i use shaderED to make teh basic structure then do all the stuff in notepad
