Hi guys, is my experiment on Random of Object Info Node.
After participating on Cgcookie Architecture rendering contest, I found out I’m constantly duplicate the same material just to slightly adjust or replace difference dirt map of the material. So i decide to create a node group that can change difference dirt map randomly (like 2 to 4 type) in just one material. Here is my first attempt on a slightly simple procedural material of the snooker ball (numbers are texture).
C&C are welcome, thanks.
