Suppose we generate meshes in editor then save to asset database, could Mesh LOD still be applied to such mesh assets? Or is it specifically only for imported ones? Would be nice if it can apply to generated ones that were not imported but were saved as assets.

I don’t see why it wouldn’t work… but AFAIK the LODGroup works on Renderers, not meshes, so you’d need to hook those up before putting it into the LODGroup. NOTE! the asset must be written to the database FIRST, then its reference inserted into the MeshFilter, or else the change won’t persist. Her…

I believe they’re talking about the new Mesh LOD System, not LODGroups. From a quick test myself, it doesn’t seem like you can at present. Only as part of importing an external mesh format, rather than Unity’s internal .mesh format.

You can run Mesh LOD generation in the editor through the API too with MeshLodUtility.GenerateMeshLods(mesh). The code in this post provides a basic example.
