For the Elemental Ray blog, David Hackett posts a look at the new mental ray MILA material properties and base phenomenon layers in Maya 2015. This represents part two for a more expanded look at the Mental Ray Layering Library shader, where part 1 of the series can be found here. We also had a look at the Inside mental ray blog post can be found in the post Understanding and Using Mental Ray Layering MILA in Maya 2015 here.
The default layout of the MILA material is specifically set up to gain access to the most common four sections quickly. These sections include Components, base, material properties, and extra attributes.
Components are where you add and see the components that are created as mixes or layers. The Base acts as the main, or bottom layer of the material, but also as storage space for built in presets. Material properties cover overall controls for the material that will apply globally. Finally Extra Attributes will allow you to add additional frame buffers for output when the material is called for render.
If you are interested in what MILA has to offer and how it all comes together, be sure to check out the post for The Layering Library (MILA) part 2 over at Elemental Ray here.
