In most locos you can see how blinds are set from outside (Traxx, CD 163, etc) but not on the Pafawag family.

Others are opaque. Transparency sorting is a bane of 3d rendering. In theory simple sorty by object origin from camera should do the trick in this case, but it wasn't working for whatever reason, or caused even more severe problems when sorting with other transparent elements like particle effects.
