I modeled a room as a solid box made of air. I added a decal to one of the faces to represent drain cover on the floor. The visibility of decal when the same part file is opened in SW 2012 and 2014 is different: in 2014 I only see decal when viewing the face directly, but in 2012 I also see it when viewing the other side of the face through the part. Obviously 2012 way is closer to how I intended this particular decal to be seen. How can I arrange this in 2014? The model made in SW 2012 is attached.
