I used a filled region in a detail component Rfa. I nested the filled region in another Rfa.(site cat)
On project level the site Rfa works fine except in views > advanced model graphics > cast shadows.
The filled region casts shadows on the ref. plane. Obviously the filled region is lying on a certain hight above the ref-plane although it was set to be on and not above the ref.plane.
Any idea's to lower the hight of the filled region ?
