Features:

Area, spline, planar, linear and point tracing options. 1D and omnidirectional
static mesh voxelization distribution and texture map instance projection
static mesh and actor(blueprint) instancing (with probability setting)
convex / concave detection mode
clustering
scale falloff gradient with ratio control
look-at rotation options and target (3d widget)
use spline from separate actor
apply spline rotation to instances
fixed instance distance along spline
tracing special behavior based on physical materials and selection of actors
ignore actors from trace (trace passthrough)
Avoid overlapping (2 methods) and instance minimum distance
Slope angle distribution
function in control panel with autoPopulate (append selected static meshes or blueprints to selected ia scatter(s))
function in control panel to convert scattered instances to actual scene actors
Scattering area can be rotated to face any direction
Separate instanced mesh relative scale
Complete instance rotation control with rotation snapping
Complete instance uniform and non uniform scale control
Align instances to normal
Instances distance from face (along normal)
Instance collision type selection
both construction script and event graph / runtime execution Version: 5.1 Home Page: https://www.unrealengine.com/marketplace/en-US/product/ia-scatter
