UFoliageType

The maximum angle in degrees that foliage instances will be adjusted away from the vertical

Custom collision for foliage

Whether to override the lightmap resolution defined in the static mesh.

Whether the foliage receives decals.

If true, the foliage will be rendered in the CustomDepth pass (usually used for outlines)

Whether new seeds are spawned exclusively in shade.

If enabled, foliage will render a pre-pass which allows it to occlude other primitives, and also allows it to correctly receive DBuffer decals.

Controls whether the foliage should cast a shadow or not.

The CollisionRadius determines when two instances overlap.

The foliage instance's collision bounding box will be scaled by the specified amount before performing the overlap check

If checked, an overlap test with existing world geometry is performed before each instance is placed

Optionally write this 0-255 value to the stencil buffer in CustomDepth pass (Requires project setting or r.CustomDepth == 3)

Mask used for stencil buffer writes.

If layer names are specified, painting on landscape will limit the foliage to areas of landscape with the specified layers painted

Lighting channels that placed foliage will be assigned.

Controls the type of lightmap used for this component.

X, Y is origin position and Z is radius...

Specifies the oldest a seed can be.

Allows a new seed to be older than 0 when created.

The seed that determines placement of initial seeds.

Specifies the minimum value above which the landscape exclusion layer weight value must be, in order for foliage instances to be excluded in a specific area

Specifies the minimum value above which the landscape layer weight value must be, in order for foliage instances to be placed in a specific area

Mobility property to apply to foliage components

The number of times we age the species and spread its seeds.

When two instances overlap we must determine which instance to remove.

Overrides the lightmap resolution defined in the static mesh

The scale range of this type when being procedurally generated. Configured with the Scale Curve.

The minimum distance between foliage instances

A random pitch adjustment can be applied to each instance, up to the specified angle in degrees, from the original vertical

If selected, foliage instances will have a random yaw rotation around their vertical axis applied

If checked, foliage instances will have their normal alignment adjusted by the Reapply tool

If checked, foliage instances will have an overlap test with the world reapplied, and overlapping instances will be removed by the Reapply tool

If checked, the density of foliage instances already placed will be adjusted by the density adjustment factor.

If checked, foliage instances not meeting the ground slope condition will be removed by the Reapply too

If checked, foliage instances not meeting the valid Z height condition will be removed by the Reapply tool

If checked, foliage instances painted on areas that do not have the appropriate landscape layer painted will be removed by the Reapply tool

If checked, foliage instances not meeting the new Radius constraint will be removed

If checked, foliage instances will have their pitch adjusted by the Reapply tool

If checked, foliage instances will have their yaw adjusted by the Reapply tool

If checked, foliage instances will have their X scale adjusted by the Reapply tool

If checked, foliage instances will have their Y scale adjusted by the Reapply tool

If checked, foliage instances will have their Z scale adjusted by the Reapply tool

If checked, foliage instances will have their scale adjusted to fit the specified scaling behavior by the Reapply tool

If checked, foliage instances no longer matching the vertex color constraint will be removed by the Reapply too

If checked, foliage instances will have their Z offset adjusted by the Reapply tool

Array of runtime virtual textures into which we draw the instances.

Instance scale factor as a function of normalized age (i.e. Current Age / Max Age).

Specifies the range of scale, from minimum to maximum, to apply to a foliage instance's X Scale property

Specifies the range of scale, from minimum to maximum, to apply to a foliage instance's Y Scale property

Specifies the range of scale, from minimum to maximum, to apply to a foliage instance's Z Scale property

Specifies foliage instance scaling behavior when painting.

The number of seeds an instance will spread in a single step of the simulation.

The ShadeRadius determines when two instances overlap.

The radius used in single instance mode to detect collision with other instances

Specifies how much seed distance varies from the average.

Translucent objects with a lower sort priority draw behind objects with a higher priority.

A GUID that is updated every time the foliage type is modified, so foliage placed in the level can detect the FoliageType has changed.

Number of lower mips in the runtime virtual texture to skip for rendering this primitive.

Controls if this component draws in the main pass as well as in the virtual texture.

Specifies a range from minimum to maximum of the offset to apply to a foliage instance's Z location

Handles reading, writing, and reference collecting using FArchive.

1. Now use the Mobility setting to control static/dynamic lighting

When painting on static meshes, foliage instance placement can be limited to areas where the static mesh has values in the selected vertex color channel(s).

When unchecked, foliage instances will be placed only when the vertex color in the specified channel(s) is above the threshold amount.

Specifies the threshold value above which the static mesh vertex color value must be, in order for foliage instances to be placed in a specific area
