I had a similar idea for this jam, really satisfying to carve with a gun though.
thanks for trying it out yeah I've seen yours too how did you get carving to work?
CSG Mesh Subtraction, not really meant to be used during runtime since it's a prototyping feature, but it works pretty well!
Eyy nice my way was using unreals chaos destruction system meant to simulate explosions, it was a fight to get it working for carving lol
