Terrain Painter

The Terrain Painter is a lightweight, scene-aware authoring tool for making local grass-map changes while viewing the actual Grassworks result. It is not a replacement for a full image editor.

Two starting workflows

Blank

No grassMap + painter enabled. The painter starts empty and you paint grass into the terrain.

Refinement

Existing grassMap + painter enabled. The existing map becomes the starting canvas and you add or remove detail.

Painting controls

  • The current map is shown in the top-left.
  • Draw and erase are supported.
  • A grayscale/value control changes the painted value.
  • Brush size is adjustable in world-space units.
  • There is no brush softness/falloff control.
  • Erasing restores white/no grass.

Orientation and quality

flipU and flipV correct UV orientation when painting appears mirrored or reversed. Current defaults are flipU: false and flipV: true.

Painting quality selects a fixed LOD for the painting area: high, medium, low or veryLow. It does not use normal distance-based LOD switching while painting.
