====== Making a new 'fractal heightmap' project ======

//Note: //This page follows-on from [[l3dt:userguide:newmap|making a new project]] page.

The //Fractal parameters// wizard pane (below) is very simple, which reflects the fact that L3DT's [[l3dt:algorithms:hf:fractal|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.
