Making a new 'fractal heightmap' project

Note: This page follows-on from making a new project page.

The Fractal parameters wizard pane (below) is very simple, which reflects the fact that L3DT's fractal algorithm is itself very simple.

  • The map must be a square power of two, ranging from 128 × 128 to 8192 × 8192 pixels.
  • A low Fractal persistence value makes the terrain smoother, and a larger value rougher. The recommended range is ~ 0.45 to 0.65.
  • If you select the Edge wrapping option, the top/bottom and left/right borders will wrap seamlessly, giving infinitely repeatable terrain.
