Cutout - see through wall

Hey!

I’m having a problem. I have a project with perforated metal plates. When applying the cutout material to the wall, enscape revit sees through the whole wall.

I’ve tried to seperated the walls, so that the perforated plate is it’s own wall geometry. But it still happens.

Does anyone know how to make the cutout not see through the wall and only the geometry?

For the purpose i’ve “oversized” the cutout. I guess it’s something to do with enscape only showing wall materiale as onesided? And when using cutout, you see the back side of a material, that’s only one-sided, and thus see through the wall.
