I have a wall of windows and I've created a custom door panel for a door in that wall. For some reason the door looks perfect in 3D if you look from the inside space, but when I look at it from the outside the wall material "bleeds" through so that the door is completely opaque and the same material as the wall.
If I switch to any of the door panels that the ArchiCAD library provides the door looks perfectly normal from both sides..
I created the custom door panel using slabs and saved it as an door panel (I'm using ArchiCAD 16, and there was an option for this in the "Libraries and objects - save choice as - door panel". Now my ArchiCAD is in Finnish, so I'm not completely sure of the path, but you catch my drift).
What can I do to get the door to look normal from both sides?
