This is the process of a simple hand-painted tileable texture.
- I started by just tossing down a bunch of different browns. I’m not trying to create specific shapes, just to make some variation while avoiding anything that will look weird or obvious when tiled.
- I added shadows for cracks and rocks. I sort of start to define shapes here but again, the priority is just making sure it tiles well.
- I added highlights on the cracks, edges of the rock-hole-shadows, and along the dirt to define the shape more.
- Added rocks!
When I’m doing a tileable texture, I apply an “offset” filter with both directions half the size of the full image. So in this case, this is a 512x512 texture, so I set the offset filter to 256x256. Once you have applied the filter once, you can do it again with ctrl + f, so I’ll just hit that occasionally while working to make sure I’m covering all portions of the image.
More complicated textures are obviously harder, dirt is about as easy as it gets.
