Stuck on "Running Lightmass" when building map
Building worked fine until I added a couple of the deathpose mason meshes, weapons and blood splatter. After I did this the “Running Lightmass” happened.
Any idea what the problem might be?
Do you have an importance volume in your play space? Check the swarm log (not the green bar) for more info as it builds. It can take a long time either way.
