Control backface material texture orientation?

Here is a rectangular plane. I bent it so you can see both the upper face as well as the backface. The orientation of the upper face is correct, but the backface has the texture rotated about by I don’t know which angle. Obviously I’d want the backface to have the same orientation as the upper face.

How can I rectify this? I would like to know the quickest way to make it so that the backface orientation follows the upper face.

Note: The rectangular object is not oriented orthogonally with the XY-grid. And the material bitmap texture is defined in ocs mapping (box style). In my case the bitmap is set to be rotated 18°

You’ll have to attach a 3dm file for anybody to be able to help.

Thanks,

change your mapping from WCS/OCS (Box style) to WCS/OCS. Do the same for your transparency texture, then you can enable it too to get the grille you are looking for

To control backface material texture orientation, you’ll typically need to manipulate the texture mapping and potentially use shader techniques to achieve the desired effect.
