Lovin' VRAY for Maya's VRAY Blend material
Sometimes the most simple things tweak my brain. I remember the pain of having
to use mix8 nodes in Mental Ray. This mucho bettero.
1. slap down a vray blend MTL.
2. Throw a semi transparent shader in as your base.
3. add in another shader with a blend amount or use a texture to determine blend amounts.
That's it. Insta-layered shader. Awesome.
