Forest Generator

Doubled – Forest Generator & Terrain Painter A pair of editor tools for procedural world building directly inside the s&box editor. Forest Generator Scatter prefabs across your scene procedurally with full artistic control. • Prefab list with weighted randomization – define any number of prefabs (trees, rocks, props…) each with an independent spawn probability weight • Bounding box placement – draw the area directly in the scene or set it manually • Perlin noise density – control where prefabs cluster and where they thin out using noise scale and threshold • Random scale variation – set min/max scale per generation run • Align to terrain normal – objects orient themselves to the slope they're placed on • Seed-based randomization – repeat or vary results with a single seed value • Preset save/load – store and recall your favourite configurations as JSON files Terrain Painter Procedurally apply materials to your terrain in one click using three purpose-built layers. • Base layer – the ground material (e.g. grass) that covers everything • Shore layer (sand) – paints a beach band around a configurable water level using world-space height. Supports smooth blending into the base layer, organic noise displacement on the shoreline edge, and a max-height cap to prevent painting sand on cliffs • Slope layer (rock) – paints steep areas with a configurable slope threshold. Fades smoothly into the underlying material (grass or sand) using a configurable blend width. Respects a shore-avoidance zone so rocky cliffs near the water correctly show sand underneath, not rock • Smart two-material resolve – because s&box terrain blends exactly two materials per texel, the painter automatically picks the best pair (rock over sand on a rocky beach, rock over grass inland, sand over grass on a flat beach) • Preset save/load – same JSON system as the Forest Generator
