HLOD error on Lightmass build: Instanced meshes don’t yet support unique static lighting for each LOD

Hi,

I’m getting this error every time I try to build the lighting. I saw another user get this error and it was to do with how they had vegetation on their terrain material. I do not. I’m just using the default terrain material. Any ideas?

MyMapName_HLODLayer_0234820cca09fe99 Instanced meshes don’t yet support unique static lighting for each LOD. Lighting on LOD 1+ may be incorrect unless lightmap UVs are the same for all LODs.

This is not an error, it’s a warning. It’s not even a warning really, it’s just telling you how lightmass behaves with ISMs.

If your meshes look fine then just ignore it.

It’ Stops the lighting being built for all my HLODs.

UPDATE:
If I delete my HLODs the lighting builds fine. It just seems to be a problem with building lighting for HLODs

Possibly related to this error I started getting out of the blue. Building HLODs taking forever. - #2 by DanielOS96
