I created a standard ico sphere in Blender with 5 subdivisions and generated UVs and exported it to OBJ format. When I import it the faces are strangely shaded with the default standard shader. The triangle faces have gradients that don’t blend into their neighbours, creating jagged patterns. The shading on the default Unity sphere’s triangles are smooth despite having fewer faces than my ico sphere.
I wonder if there is some ‘miscommunication’ between Blender and Unity that mess up the vertex normals but the face normals look fine in Blender. Do you understand what happens here?
