Shadows are cut by clipping plane

Hey Rhino Layout team,

another Problem i face is that the engine that renders the shadows ignores my clipping plane selection.

Is there a work around or is it simply not possible.
It doesnt matter which Displaymode i choose.

Shadows On:

Hi Milan -

Can you post both the 3dm file and the custom display mode that are involved here?
