Floor Plan Cut Plane Shadows & Sun Study


This question has been asked previously, but I'm wondering if there's anything new in AC27. 


Is there a way to do a sun study of the floor plan with shadows from elements above the cut plane (upper floors and roofs) taken into consideration? Currently, if you show shadows in a 3D cutaway view, it shows sunlight coming in above the walls.


Operating system used: Mac Apple Silicon 14 Sonoma

Did you find this post:


I couldn't figure out how to get YouTube to give English subtitles to this Russian video ... but I presume it was showing how to achieve a material for the ceiling/roof that is transparent yet still casts a shadow, which is the typical way of achieving your goal.


If such a material can be created... then if a Graphic Override could apply that for you (vs manually changing materials), it would be a great solution.  Hopefully someone who has tried this will post... or you have time to experiment...
