Using the National Map Viewer, I brought USGS data from the Glen Alum Mine in West Virginia into Maya. This elevation data was measured after the mountain was stripped – you can see the flat areas. In the next step, I’ll be adding a coal texture to the footprint of the mine.
On the technical side of things, I’m having trouble getting my writetoColor buffers to save out as expected. It’s starting to seem like it could be a bug in Maya 2015 – the Master Beauty pass renders out fine, so that means the contribution map is right. I think I can workaround the problem with render layers: since my misss_fast_skin is split into diffuse, specular, front, mid, and back channels, I can use material overrides.
