Troubleshooting surfaces bent incorrectly when mia_roundcorners shader is applied

If you are using the mental ray mia_aroundcorners shader and the surfaces are bent incorrectly in your render, check the normal direction by selecting Display > Polygons > Face Normals or Display > Polygons > Vertex Normals. You may need to reverse your normals.
