Debris / Rocks

Vegetation vegetation.debris

Scatters rocks where they collect: talus below cliffs and steep slopes (or the Talus input, e.g. Thermal Erosion's Debris) and a population's Dead zones. Outputs a Density mask and one point per rock.

Output with default settings, rendered by LibreTerrain.

Settings

Setting	Default	Range / options	Description
Species	rock		Name written with each point in exported point files (e.g. scots_pine), so import scripts can pick the matching mesh.
Coverage Mask port	0.8	0 to 1	Density where debris gathers most.
Shedding slope	32 °	0 to 90 °	Slopes steeper than this shed rocks (when no Talus input is connected).
Reach	60 m	0 to 2,000 m	How far rocks roll out from steep ground, in metres (without a Talus input).
Talus	1	0 to 1	How much debris lies on talus (the Talus input, or ground below steep slopes).
Dead zones	1	0 to 1	How much debris lies in dead zones (Dead zones input).
Patches	0.4	0 to 1	Groups plants into clumps and clearings. 0 = even cover.
Patch size	50 m	5 to 20,000 m	Typical size of clumps and clearings, in metres.
Spacing	4 m	0.25 to 1,000 m	Minimum distance between two points, in metres.
Rotation min	0 °	0 to 360 °	Each point turns by a random angle between Rotation min and max.
Rotation max	360 °	0 to 360 °
Scale min	0.4	0.01 to 100	Each point gets a random scale between Scale min and max (1 = the mesh as modelled).
Scale max	1.8	0.01 to 100
Seed	0	0 to 999,999	Change for a different variation.

Mask ports

Settings marked Mask port can be driven by a mask. Click the setting's Mask port button and connect a mask to the new green input: black scales the value to 0, white keeps the value you set.
