Explosive canister model for Pipe/Factory lane for use as an environmental hazard against enemies. The yellow material in the canister is, in universe, a highly volitile form of the REVN's central resouce; Ichor. Canisters spawn on the hatch's bottom platform and elevated up. The spawn hatch has a depth-based material on an interior plane that allows it to be placed flat on whatever surface and not have to worry about seeing the floor plane or the canister clip as it's raised, instead looking like it has emerged from a shadowy volume.
"Energized Ichor" material animation.
