Rock Diffuse

This was quite a challenge as I made a point of not using any photo textures. I built the texture up in layers, using the uvs and the ambient occlusion from mudbos as a point of reference.

I started with a general grey, using textures brushes to get a little variance in tone. This seemed too dark, so I lightened it up and added some colour variance, adding some green patches with a stiple sort of brush.

I then added the AO map in. After  looking at some pictures of granite I saw that white splotches are common so I added this in.

I then added some grass and moss, in a bright dark green. To make this I used another stipple brush in a dark green and then added a lighter one on top. I then went in with the lighter colour and added some grass like lines.

I then added some white dots and lines to give a little fantasy style twist.

I then upped the constrast on the grey background and added in some more tone.

It looked pretty good on the stones but there was something missing that I couldn’t put my finger on. The issue was that moss generally only grows on one side. I then tried this, but actually thought the other one was better.

Combining them looked pretty good, as it made it look less like one rock model.
