Low memory crash...HLOD mesh generation crashes the editor for generating 1 big HLOD for a sub level

HLOD mesh generation crashes the editor for generating 1 big HLOD for a sub level.

The settings used were to create a new material with new textures for metallic roughness, normal, and everything… Takes a long time and near the end it crashes…

An error message is given saying the computer is low on memory. Computer has 24 gb of memory with a gtx980m.
