I went to Crystal Cove and took lots of rock photos. Few rock assets came out great result.
Rock01 flat color view. There was repetitive cracks on the surface. It looks boring so I removed them in Zbrush.
Rock01 highpoly modeling view
Rock01 realtime render shot in Unreal 4. It was 800 tries and 1k texture.
Rock01 texture breakdown. It has small lighting information so I took it out by using Worldmap normal information.
Rock02 flat color view. I realized there is big lighting information on the right which must to be removed.
Rock02 highpoly modeling view.
Rock02 realtime rendering shot in Unreal 4. This asset has 1.2k tries and 1k texture.

Treebark01 tiling texture test.
I was wondering that the photoscan data could be used as tiling textures. Using Substance Designer was greatly helpful to make tiling textures.
