Spawn Detail Settings control how strongly MegaWorld writes a terrain detail prototype into the terrain detail map. This component is used for Unity/Terrain Detail prototypes in tools such as Advanced Brush and Terrain Spawner.

​
Settings

  • Use Random Opacity randomizes the written detail strength per pixel. This helps break up uniform coverage and makes grass feel less repetitive.
  • Density sets the target detail strength MegaWorld writes into the detail map. Higher values produce denser grass or detail coverage.
  • Failure Rate (%) adds an extra chance to skip spawning on a pixel. Higher values create a sparser result.

​
How it works

  • MegaWorld evaluates the mask and filter fitness for each terrain detail pixel.
  • It converts that fitness into a target strength from 0 to Density.
  • If Use Random Opacity is enabled, MegaWorld multiplies that fitness by a random value before converting it into target strength.
  • If Failure Rate (%) triggers, the target strength for that pixel becomes 0.
Use Use Random Opacity together with a medium Density when you want natural grass variation. Increase Failure Rate (%) when you want more empty patches without changing the overall mask shape.
