Hi! I am in the archviz industry and would like to carry out projects based on unreal. I have built a demonstration apartment to try out different techniques. I’ve been kicking around around with these light artefacts for a long time. I tried breaking the walls into individual boxes and setting them in the overridden Lightmap res value of 700. It seems to be related to the fbx and datasmith mapping. I turned on the Datasmith FBX Importer plugin, saved the objects and imported them again. Still the same… Can anyone help me?
