AGeometryCollectionRenderLevelSetActor

[AGeometryCollectionRenderLevelSetActor](API\Runtime\GeometryCollectionEngine\AGeometryCollectionRenderLevelSe-) An actor representing the collection of data necessary to render volumes.

API > API/Runtime > API/Runtime/GeometryCollectionEngine

AGeometryCollectionRenderLevelSetActor An actor representing the collection of data necessary to render volumes. This references a ray marching material, which is used internally by a post process component blendable. This is a workflow that can be improved with a deeper implementation in the future if we decide to. Note that behavior with multiple render level set actors isn't currently supported very well, but could be improved in the future
