A wind turbine made for the Arctic Research Base. As this model was so large, we used a RGBA 4-way blend shader. Previously this setup was difficult to use as you could only paint the vertex colours inside of Unity, which was a very destructive workflow.
I re-wrote the RGBA 4-way-blend shader inside of 3Ds Max, which enabled much faster development iterations as well as enabling a correct LOD2/3 atlassed bake.
