Simple Filter Settings are the lightweight filtering workflow used in several non-mask-based MegaWorld tools. Unlike the full mask filter stack, simple filters evaluate fitness directly from terrain or raycast data.

​
Available checks

The current code supports:
  • Height
  • Slope
  • Global Fractal Noise

​
Core behavior

Each enabled check returns a fitness value, and the final simple-filter fitness is the product of those values. This means:
  • disabling a check removes it from the calculation;
  • stronger restrictions reduce the final fitness;
  • height, slope, and noise can be combined together.

​
Height and slope falloff

Height and slope checks support:
  • hard cutoff behavior
  • additive falloff behavior
  • min/max falloff variants

​
Noise behavior

The noise part supports:
  • remapping
  • inversion
  • range control
  • fractal-based variation

​
Preferences

Simple-filter visualization is controlled separately in:

Where Simple Filter Settings are used

Simple Filter Settings are especially relevant in tools such as:
  • Spray Brush
  • workflows where a full terrain mask pipeline is not needed
Use Simple Filter Settings when you want lightweight filtering on top of a direct tool workflow. Use full mask filters when you need stack-based terrain masks and blend operations.
