Non-portal objects placed inside walls

I’m trying to mod some gothic-style reliefs which replace wall tiles. My first thought was to simply make a window but list it under decorations instead of windows. Surprisingly it doesn’t work. Am I forced to move it to windows category?

I don’t know much about the problem, but if you haven’t already, you could test if it works when you move it to the windows category. If it doesn’t, you might have a different problem, and fixing that might make it work when it is in the decorations category. (Sorry if this is really obvious to you, I don’t mean any harm:slightly_smiling_face:)

This topic can be closed as it is no longer a problem to list a window under any other category in the new builder.
