For the past year or so I've been learning to write real-time shaders in high level shading languages like Cg and HLSL. In the course of learning, I've created a library of shaders that I've decided to post on my web site for other 3DS Max artists to use. The shaders include features like normal mapping, offset/parallax mapping, point light attenuation, a simple version of global illumination, etc. You can get them here:

Feel free to use these for anything you want - private projects, professional projects, etc. They're completely free.
I'd love to get some feedback on them. If you apply them and something doesn't work or you need more information, I'd love to hear from you. Or especially if you are good at shader programming and find something that I can improve, please let me know. I'm an artist, not a programmer - so they may not be perfect
Have fun with them and let me know what you think.
