I recently bumped into this problem. Looks like an old one:
Any chance to fix it for GH2?

Anyone taking this into account? Thanks!
also bumped on this today
looks like if a mesh intersects with the plane on which the shadow is generated, the shadow is also cast backwards
shadow on XY plane:
shadow on XZ plane:
Mesh_Shade.gh (18.7 KB)
half_intersecting Vs quarter_non_intersecting sphere with double rays:
Mesh_Shade_half_quarter_spheres.gh (15.3 KB)
behavior is the very same on 7 SR35 (7.35.23280.19001, 2023-10-07) and 8 SR1 (8.1.23318.13001, 2023-11-14)
another post another year…
