Continuing from last months scenic hammer are a bundle of improvements.The biggest improvement is GameObjects can now parent each other in hierarchy the same way as scene, Hammer had an archaic way of handling this before so it's quite the overhaul to get here.
This means you can make lifts with buttons and lights, but mind your head on the ceiling.Other improvements include:
Scene prefabs can be dragged into the map
You can paste GameObjects from the scene editor into your Hammer map
General bug fixes including: transforms, copying, undos, gizmos stick to objects, and scene meshes can be selected now
