So here’s a little trick to get some dodgy hacky shadows in Nuke , by comparing projected and “rendered” pWorld passes we can derive the difference easily and use that as a shadow matte. Still aliasing and various issues, but works pretty well actually.

Node requires geo, camera, bg and lights. Supports all regular nuke geo.

*Nuke script with gizmo/group , Geo needs reloading.
