Happy April 10th! I was going to do a series of describing different V-ray procedural shaders, but instead, I decided to post the max file on here for everyone's enjoyment. If there is a need for other versions, I can post them on here as well. There are 10 different shaders in this file.
The nice thing about these shaders being procedural is that there are no texture maps to link to. So as long as you have max, they will work. Enjoy!
