Sorry for the long silence folks. We over at RUST ltd. have been working on something BIG! Our very first product for the Unity asset store! XD
"Alloy", as it is called, is the refined version of the physically-based shader system that we used for Museum of the Microstar. The package is planned to have the full set of shaders, documentation, working examples, etc and will be followed shortly by a planned video tutorial series.
If all goes according to plan, we will release on Tuesday. Keep an eye out. ;)
