[osg-users] Shadows on two-sided polygons

I use two-sided polygons (as I display no real objects but mathematical
ones like planes this makes sense) and use shadows on them.
After upgrading to 2.8.2, this does no longer work. I get the correct
shadow on one side of a plane, but if the shadow should be on the other
side, I get strange artifacts but no shadow.
Is there a setting to change the shadow to two-sided? Thanks for your help.
