Hello everyone,
I’ve recently come across an issue where the engine will crash when I try to generate LODs for a level using the level details panel and world composition.
In the level that I’m trying to generate lods for, I have blueprint actors that store further blueprint actors with modular house pieces (basically a street blueprint which spawns modular house blueprints). I’ve narrowed the problem down to these blueprints but beyond that, I have absolutely no idea.
Does anyone have an ideas or suggestions?
The crash log is as follows:
