As part of my application to a studio on the East Coast, I was asked to complete a terrain art test. The requirements of the test were to make a non-tileable cliff face with a projected normal map and a hand-painted texture.

I began by modeling the initial low-polygon mesh, then imported the mesh into Mudbox and completed a high-polygon sculpt. I then projected the high-poly mesh onto the low-poly in 3DS Max. I used the resulting normal map as a guide to paint the color map.

This is the original low-polygon mesh.
This is the high-polygon sculpt that I created in Mudbox. Approximately 64 million polygons.
This is the final low-polygon mesh, with the high-poly sculpt projected onto it. Also attached is a 100% hand-painted diffuse texture and specular map.
