How do I prevent invalid lightmaps when exporting/importing to Unreal Engine

Hi, I’m testing the workflow from Twinmotion to Unreal engine (5.1-5.3). One issue I’ve run into is that at least all the tree have an error with their texture. The fix is changing the lightmap for the mesh (each tree) to 64 (from 128). Having to do this for every tree could get rather time consuming. Is there another solution? Thnx in advance.
