version 2.09 [24.Apr.2023]

• fixed a bug with landscape physical materials. now landscape LayerInfo physical materials are taken into account for special behavior
• added “refresh ia actter every frame” option to make ia scatter work with animated surfaces and parameters in runtime and in cinematics
• now clustering works with voxelization
• changed ia scatter behavior, now the scale transform of ia scatter blueprint is also taken into account
• added MF_ia_foliageWind
• added ia scatter version number in ia scatter debug category
• removed BP_ia_scatter_noGeometryScript
• enabled nanite in some of the assets
• added some more assets

version 1.98 [07.Apr.2023]:

• added voxelization distribution method
• added texture map support
• moved instance collision type and instance physical material to ia scatter instance inheritance category. added cast shadow, culling start/end
• fixed random seed bug. now, enabling clustering and changing clustering settings does not affect the cluster center. this means an ia scatter can be used to cluster instances around instances of another ia scatter
• exposed ia scatter parameters to the sequencer for animating in cinematics.
• fixed a bug that resulted in ia scatter area resetting on ia scatter duplication
• added two more assets

version 1.86 [20.Mar.2023]:

• added clustering
• added point (spherical omni) tracing option
• added invert tracing start/end option
• added relative instance probability
• replaced EUW_ia_scatter_convert_tool with EUW_ia_scatter_control_panel. now there is an option in the control panel to populate selected ia scatter blueprints with the selected static meshes and blueprint actors
• changed tracing exclusions system. now it is called special behavior and multiple physical materials and actors can be selected to participate in this special behavior
• added option to assign physical material to instances
• added variation to the default ia scatter instance material
• added one more asset
• fixed the scale of the included assets

version 1.69 [10.Mar.2023]:

• added convex/concave detection mode
• added option for fixed instance distance along spline (suitable for brick walls for example)
• ia scatter can now execute at runtime as well. this means parameters can be modified during play
• added tracing exclusion options based on physical material: ignore/do not populate on PM_ia_scatter/populate only on PM_ia_scatter/populate only under PM_ia_scatter
• added hierarchical instances option
• added tooltips and descriptions
• added extra assets

version 1.54 [19.Feb.2023]:

• added no tracing button
• renamed “tracing method” to “distribution method”
• added display less instances button in ia scatter control panel and number of less instances setting in the ia scatter debug panel
• removed the spline type selection since it was causing problems. spline type can be changed graphically by right clicking on the spline
• added display proxy button (beta feature, proxies may be improved in the future)

version 1.49 [13.Feb.2023]:

• added area and planar downwards tracing options
• added spline, linear and point downwards and omnidirectional tracing options
• added actor(blueprint) instancing support
• added scale falloff gradient with ratio control
• added instances look-at rotation options and target (3d widget)
• added tracing exclude/interrupt by physical material
• added actors to ignore from trace (trace passes through)
• added option to use spline from separate actor and apply spline rotation to instances
• added refresh ia scatter button
• added randomize seed button
• fixed rotation order. now align to normal and random rotation work together properly
• fixed ia scatter updating when dragged, resulting in much faster workflow
• fixed arrays not getting cleared properly
