FSetExternalCollisionsFromPrimitiveDataflowNode

Sets the ExternalCollisions attribute on each selected transform to a primitive shape (sphere / box / capsule) auto-fitted to that bone's geometry bounds.

API > API/Plugins > API/Plugins/GeometryCollectionNodes

Sets the ExternalCollisions attribute on each selected transform to a primitive shape (sphere / box / capsule) auto-fitted to that bone's geometry bounds. Any existing ExternalCollisions entry on the selected transforms is REPLACED.

Shapes written here flow through the same runtime path used by static-mesh-imported primitive collisions: the GeometryCollection asset must have bImportCollisionFromSource enabled for the simulation to consume them.

Empty/unconnected selection authors the shape on all rigid-leaf transforms.
