I’m trying to implement mass in my project for enemies, but I’m getting this error:
It’s causing the actors to not appear, but the mass debugger says entities have been spawned. I’m not quite sure what this error means. I tried to look it up, but there are quite literally no results. This is what the output log says:
(Ignore the play montage error, I have a play montage node with no animation set)
I’m very new to Unreal so I’m still learning the proper way to debug things, and I haven’t figured out what all the errors mean yet. Does anyone know how I can fix this?
that MassLODCollectorTrait validation fail usually means the LOD collector has no valid LOD config.
on your Mass entity config / LOD trait check: Distance LOD has entries, at least one LOD is enabled, and the fragment it writes (like DataType or LOD index) is actually registered. if you removed the default processor or renamed the trait the collector has nothing to write to and it fails validation before entities appear.
quick sanity: duplicate the sample Mass config that ships with the MassAI template, spawn one agent with that untouched, see if it appears. then diff your config against it to spot the missing LOD entry.
