Can't build my level lighting

I can’t build my level because of attached log jpeg, any help would be nice.

Any help??

Please help, i’m stuck. Any idea?

Are your lightmap UVs the same for all LODs?

What does it mean? Actually i’m using marketplace pack for foliage and that’s demo scene looks normal. Could you help me to fix lightmap uv problem?

Could you pease help?

Is there any solution, please write?

You need to create lightmap uv’s for those instanced static meshes. Here is a tutorial. Auto-generate UV for lightmaps Issue - Rendering - Unreal Engine Forums

Thanks for answering but foliages has uv maps with 2 channel and package is from UE4 marketplace

I deleted all the foliage but still can’t build, and no one helps. I’ll have to move project to another engine at the end
