set_decal_color
DestructiveIdempotent
Set an editor-world ADecalActor's DecalColor by label, returning the resulting RGBA. Pass exactly four numbers; other lengths keep the current color.
Instructions
Set DecalColor on an editor-world ADecalActor found by label; it only shows if the decal material uses a Decal Color node. A color that is not a 4-number array is ignored (current color kept). No undo, dirty flag or save; returns the resulting r, g, b, a.
Returns: { actor_label: string, r: float, g: float, b: float, a: float }
