Description

The wrapper is stored in the actor's TerrainMaterial. A null Material, a wrapper, and a special engine material need none, and a material that is not a surface material cannot have one: TerrainMaterial is then cleared, so a stale wrapper never outlives a Material change. When TerrainMaterial changes, a PostEditChangeProperty for it follows, and the actor re-creates its terrain with the new wrapper. The property-changed hook for Material does the same without that event, since the actor's own Material change re-creates the terrain next.
