Hello, It’s nice to have “Use render meshes” in the OBJ export, but unfortunately, it loses some stuff in the process. It is not including effects such as Edge Softening. On the right, you can see that the Extract Render Mesh command gives me expected results - correctly mapped and softened mesh.

Important: If during OBJ export, you don’t use the “Use render meshes” option, you might get softened mesh but good luck with texture mapping…
