i have revised the check of the recompute tangents and is selected… i have checked the normal and the full uv precission too… but still shows the triangulized shadows…
the UV of the mesh was created by the udk4 static mesh editor so i should think the problem is not here…
I like the visual effect from the first image… when i put the asset in the world before build lights… so is there any option to build the lights keeping this smooth global shadow?
