Hi, setting custom normal and tangent inputs to the normalmap node in V-Ray seems to have no effect, here I am inverting them, but the result is no different than default behaviour.

In Karma, the normals correctly flip if I input the inverted normals and tangents to the normalmap node.

Thanks for any advice!​
