Can clipping planes clip geometry, but not clip shadows please?

I have a scene in which I want to section away some external elements to reveal internal elements, however I’ve run into a few issues with the visualization.

Raytracing gives me very no-bueno results in Rhino 8 and Rhino WIP:

In a Rendering-derived viewport setting set it’s a bit better, but the shadows are getting clipped oddly:

If I uncheck “automatic altitude” on the display mode options and set an altitude that is below the objects, it looks like it’s considering the objects generally correctly, however it’s still clipped oddly:

Because I work for an aerospace and defense company, I unfortunately cannot share the original scene, so I’ve made this quick demo example. Any way we can get the shadowing to be “normal” for such a clipped case?
Thanks!

Hi Jonathan,

I replicated your example but not quite understanding the issue or what exactly you want this to look like. Can you provide additional details? Thanks!

What I’m looking for is the shadow propagating normally, as though the geometry had been modeled in this clipped condition.

in the “real” use case, I have a section of a fuselage that is clipped, but I’m not clipping the wings… I still want them to cast shadows normally.

In this view you’ve created shows the occlusion between surfaces, I want the shadowing in the gap between the “feet” columns you’ve made, as well as the cast shadow from the larger block on top.

Like this? I added a planar surface underneath (excluded from clipping)

Exactly, but without adding a plane in the scene, because then you don’t get transparency through the shadows when you go to use _viewcapturetofile

There is an option to ignore the clipping plane shadows
