Description
CreateLeafConvexHulls (v1)
Create Leaf Convex Hulls Dataflow Node
Input(s) : OptionalSelectionFilter - Optional transform selection to compute leaf hulls on -- if not provided, all leaf hulls will be computed. SimplificationDistanceThreshold - Computed convex hulls are simplified to keep points spaced at least this far apart (except where needed to keep the hull from collapsing to zero volume).

Parameters
| Name | Description | Permitted Types | Default Value |
|---|---|---|---|
| GenerateMethod | How convex hulls are generated -- computed from geometry, imported from external collision shapes, or an intersection of both options. | EGenerateConvexMethod | ComputedFromGeometry |
| IntersectIfComputedIsSmallerByFactor | If GenerateMethod is Intersect, only actually intersect when the volume of the Computed Hull is less than this fraction of the volume of the External Hull(s). | float | 1.000000 |
| MinExternalVolumeToIntersect | If GenerateMethod is Intersect, only actually intersect if the volume of the External Hull(s) exceed this threshold. | float | 0.000000 |
| bComputeIntersectionsBeforeHull | Whether to compute the intersection before computing convex hulls. Typically should be enabled. | bool | True |
| DebugDrawRenderSettings | FDataflowNodeDebugDrawSettings | (RenderType=Wireframe,bTranslucent=True,Color=(R=0.000000,G=1.000000,B=0.000000,A=1.000000),LineWidthMultiplier=2.000000) | |
| bRandomizeColor | Randomize color per convex hull | bool | True |
| ColorRandomSeed | Random seed | int32 | 0 |
