Everytime I try to add a volumetric cloud to my game it immediately crashes unreal engine. The map is migrated from a different folder into a vr template. It used to work fine but in the vr template with the migrated map it just instantly crashes. There is a lot of data and a large map size but it worked fine before. Ty for herp

No solution here either but I have also encountered this issue today.

Initially a teammate had added the Volumetric cloud object to a map, and upon loading this map on my computer, my engine would crash with these errors

The same crash and error is also given when I add a volumetric cloud to a map and play it.

Update: We found out my teammate had added the changes while running version 4.27.2, I was running 4.27.1, silly mistake but an update to 4.27.2 fixed it on my end
