I’m doing archviz and getting this error when trying to bake my scene.
It also happens on older scenes that workded smoothly before…
I already tried to make a verification of UE 4.23 and did the clean & validate trick on the swarm agent.
My setup is an I7-7700 with 32Go of RAM.
Sorry for bumping in to old thread.
Did you find any solution?
I’m running 4.25 and have same issue.
Cleaning and validating cache of swarm obviously didn’t solve.
Blowing up the intermediate and derived data cache folder also didn’t help.
Nothing like a nice forum answer 2 years after the fact, but I was having the same issue. No answers anywhere, and no way to contact any kind of real Unreal support, so I had no choice but to keep clicking through the endless menus and drop downs in unreal until I came across something kind of obvious.
Under World settings, Lightmass, I saw that there was one of those yellow arrows indicating that something had been changed from the default and could be changed back (brilliant feature!) I clicked on that arrow next to ‘lightmass settings’ resetting that to default, then did a lighting build. No problem. NO more Divide by Zero error. No failure. I hope this helps you or anyone else who comes across this.
Hi, I found a partial solution, the issue is caused by one asset placed in your scene (not in content), In my case I delete those level recently placed assets , one by one until the build works fine again.
