I’ve attached references for my issue. I’m having shadow lines on only one model. I’ve unwrapped the elements inside maya then combined them >> arranged the uv shells. It is obvious that the elements affects each other. I’ve imported the model >> generate auto lightmaps >> Overridden light map Res to 1024 ,even higher I’ve tried to manually uving a second UV set but the same issue keeps on.
when I import each element individually, the issue goes away even if i auto generate lightmaps inside ue4. I don’t like to do so as it is not the right way I think and I will end up with a crowded, full of mini pieces scene.
I feel that combined elements are affecting each other. The bad culster shadow size of one element equals To neighbor element size. Ive tried to import separate objects and make light map to 64
Maybe you could export combined mesh right back to your 3d software and try to clean it up? Check if tere is no uv overlaps and try to reimport it? It seems strange especially horizontal lines at flat surfaces, like other mesh inside.
I initially thought it was a case of bad UVs/modeling, so I remodeled most of the mesh (minus the bevels). But when I went to lightmass to bake out a comparison image, the results looked the same.
