You can create your own texture files to use with the brush paste tool, the pattern tool, or the brush tool's custom option.
If you are going to be using the texture with the Advanced Visualizer, remember to create the texture in a square resolution.
Use 1k_square (1024 by 1024) or higher for zoom-in close-up camera shots.
A 512-by-512 square is a good size for average camera shots.
A 256-by-256 square is acceptable for average and zoom-out camera shots. It also takes up less disk space.
