Decal Scatter

Version: 1.1

Description

Scatter decals on meshes

Properties

Base Properties

Name	Description	Type
Surface	Meshes to scatter on	Actor
Decals	Decal assets to scatter	Actor
Density	Scatter density	Float
Min Scale	Minimum scale for random scale	Float
Max Scale	Maximum scale for random scale	Float
Surface Align	Adjusts the alignment of the decals to the surface.	Float
Depth	Depth of decals.	Float
Scale	Default extent of decals in cm	Integer
Sink	Pushes your instanced objects downwards, which is very practical for trees	Float
Max Count	Maximum count of scattered decals	Integer
Seed		Integer

Feature Masking

Name	Description	Type
Slope Mask	Masks objects by the angle of the underlying surface area under them	Float
Min Height Mask	Minimum height at which objects should be clamped	Float
Max Height Mask	Maximum height at which objects should be clamped	Float

Noise Mask

Name	Description	Type
Breakup	Controls the intensity of the noise/breakup.	Float
Breakup Scale	Frequency of the noise mask. This basically controls the scale of the noise	Float
Smoothness Noise	This value controls how sharp/soft the noise mask is	Float
Warp Noise	Deforms the noise mask, which can result in some really interesting swirly mask shapes	Float
Noise Scale Multiplier		Float
Noise Scale X		Float
Noise Scale Y		Float
Noise Scale Z		Float

Border Masking

Name	Description	Type
Border Offset	Masks the scattered objects along the surface's borders.	Float
Border Min	Minimum distance offset from the border mask value	Float
Border Max	Maximum distance offset from the border mask value	Float
Border Noise	Applies a noise on the border mask	Float
Border Sampling	A higher value results in more precise border masking, but at a heavier cost	Integer

Proximity Mask

Name	Description	Type
Proximity	Proximity meshes ensure that only scattered objects nearby are kept	Actor
Distance	Controls the proximity distance	Float
Sampling	A higher value results in more precise proximity masking, but at a heavier cost (especially if your proximity objects are scatter instances)	Integer

Object Masking

Name	Description	Type
Objects	Samples objects near the meshes. Unlike proximity masking, this one uses raytracing to proper mesh proximity masking, and is more costly, and only works on meshes.	Actor
Distance	Controls distance of the padding we add to the inside mask	Float
Keep Inside	When set to true, ensures that we only keep what's inside of our meshes. This can be useful for using meshes as instancer blockers	Boolean
Invert	Inverts the mask	Boolean

Rotation Properties

Name	Description	Type
Uniform Angle	Adjust the spin of the decals. Has no effect if "Spin" is turned on.	Float
Spin	Give random spin to decals, which ensures great rotation variation	Boolean
Rotation Jitter	Additional random spin	Float
