cloud-deck

set 0× in templates and rigs

A raymarched slab of storm cloud with a billowed underside that races out from over the node, turns slowly and flickers from inside on keyed moments; `hole=true` tears a blazing hole in it and slams a volumetric light shaft down: a dust sheath with god-ray blades and a kernel of braided plasma lanes. It dims nothing but by being drawn: key the scene's lights to darken a shot. Place the node on the floor under the hole.
