I’ve imported this model from sketchup using datasmith and I need to bake lighting in this. Sharp triangle artifacts show up on most meshes after build. This is the lightmap density view, but almost no mesh has a decent lightmap. I can see the triangle artifacts in this too.
Is there a way to create fresh lightmap uvs for these kinds of mesh?
Yes in blender, or any other 3d app. There is also plugin for unreal to edit meshes, it may have decent auto uvs.
@Nawrot So using blender I can make fresh uvs that are just used for lighting and keep using the original uvs for texture mapping?
Also for the unreal plug-in, are you referring to ‘Modeling tookit editor’ ?
Yes modelling too editor.
Try to check mesh in content browser, double click it. There may be some kind of automatic creation for lightmap uvs. And remember lightmap uvs should be second uv map.
Okay! Thankyou @Nawrot
