I wanted to share with you my modified version of the Mia Material. Since I had lots of problems with the standard implementation of the architectural material I decided to make my own version some time ago. I changed some interface flaws, included some utilities like the excellent RRaytype shader by Reinhard Claus directly into the interface, and optimized working with channels.
A much more detailed description on why and what I did with the shader, as well as a short video can be found on my blog
This shader has really become my standard solution for all materials for quite some time now, and solved a lot of the common problems with the Mia Material I often hear from other people on the various forums. So I hope it will become as useful to some of you as it is to me, enjoy!Download
