Giving this some further thought, I wonder if the 3.0 to 4.0 map upgrade tool should be an immediate priority. It would give us some proper maps to play around with the features on until 4.0’s main map / props have a clear direction.
Clearly mod support is the winner interest-wise on the forum, and I would be glad to establish some dimensions for anyone interested in creating models. Right now the blocker there is deciding how to proceed with destruction and how it affects model design. I’m also considering working on some blender tools for that pipeline.
