Hi, I am using CAD models as my data source, and they come into 3dsMax as individual meshes without UV mapping. I then combine them into assemblies, each part becoming an element of the assembly mesh. So in the screenshot, I have 3 parts (the red Ɪ beam with the 2 green end plates) joined into 1 mesh. I then import them into UE4, and use dynamic lighting, so I don’t have to deal with baked lighting and UV maps. However, I get light bleed between the faces of the mesh, like the mesh is not solid. You can see this in the top left and bottom right corners of the UE4 window. The elements within the mesh touch perfectly (this is from CAD package after all), so there is no gap. There is however faces pointing at each other, which might make a difference (the beam and plates are themselves solid objects. They don’t have uncapped joins). Is there any simple way I can fix this?
Edit: Engine scalability is already set to cinematic.
