LOD's seem to produce a different lighted material... Help?

Have imported an LOD for my girder mesh. The lower poly version seems to be much lighter than the higher Poly mesh even though tehy are using the same material/Texture. Any Clues to why this is and how to fix it?
Many Thanks :slight_smile:

Could this be an issue with the mesh itself or lighting maybe?

Do you get the same result when you place it into the level + build the light? Also what happens when you just import the lod mesh -> so without the high poly mesh (do you get the same result)? :slight_smile:

Thanks for the reply… shall try this later and get back to you.
Thanks again :slight_smile:
