Realistic shadowing

Is it expected behavior that an entire beam passes through a set piece with holes in it.

I'm dealing with walls and roof pieces that are lattice like.

If I Iris down and focus only on solids of set piece with no light seeing past the edge of the lattice and select approximated, A3d recognizes it as a solid and light doesn't pass through. So it would seem A3d is recognizing it as a solid right?

If I pan and only a proportion of beam is over the edge to peak past the lattice the entire beam is visible through the set piece. And with pass through obviously the entire beam passes through. That is all fine. However with realistic selected, whether the beam is partially or completely behind the set piece the entire beam passes through and I get no cast shadow.

This set will be used for lots of cast shadows through walls and the rendering in pass through and realistic appears the same. Is is me, expected behaviors or known issue. Any suggestions?

Drawn in sketch up, imported directly as .skp  and/or dae with same results.

Tried lighting through both sides of set piece in case similar to vectorworks flip side visibility issue but same results.

Tried inserting stock wall in covering a single lattice but same issue.

    First, just making sure that you are using at least Medium quality. Low will not render the shadows even in realistic.

    Would you be willing to share or PM me a copy of your show file with snapshots taken of the views that this is misbehaving in?

    I am seeing shadows cast using Realistic and at least Medium.

    There are different shadows depending on whether I use the DAE vs the SKP. One known issue with SKP files is that not everything is double-sided so you do get items appearing transparent from certain angles (though they still cast shadows).

    Example:
    SKP:

    DAE:

    (Look at the shadow in the upper left of a wall that is one sided in the SKP.)

    One thing that might be tripping you up is if you are not using a ground plane, you wouldn't see the shadows on the floor of the SKP since it too is one sided with the solid side facing the bottom.
