The feature isn't possible right now. According to jcl though:
Quote:
Shadows on invisible models should be possible by using nontransparent models with an FFP effect that renders only into the z buffer, but nothing to the screen buffer. I haven't tried it, though.
Scripting the FFP effect is what I cannot do, since I have zero experience in this field. The effect should allow the stencil shadow to display on an invisible or none surface. The old non-stencil shadows do render on invisible surfaces, but they don't contour to non-horizontal surfaces, so they are useless.
