Features:

Preset saving and loading system

Cable system.

Area, spline, planar, linear and point tracing options. 1D and omnidirectional

Static mesh voxelization distribution and texture map instance projection

Static mesh, actor(blueprint), skeletal mesh, niagara system and geometry collection instancing (with probability setting)

voxel geometry generation

convex / concave detection mode

clustering

proximity to actor scale

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 (3 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 and instanced foliage actors

Scattering area can be rotated to face any direction

Separate instanced mesh relative scale

location grid snapping

Static mesh proxies

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 3.33 

added BP_ia_faceActor, a blueprint that always faces the camera, and flat tree assets.

added cable wind.

added new distribution method “planar grid (down)”.

added “refresh all” and “refresh selected” buttons in ia scatter control panel.

exposed “refresh ia scatter every frame” to cinematics.

now ia scatter ignores automatically every actor that has the actor tag “ia_ignore”.

added option in special behavior to ignore all actors except the ones that have the actor tag “ia_ignoreNot”.

fixed a bug with static mesh proxies.
