Thanks RoRK! I had to bump the Ray Trace quality to 7 which seems to have fixed it, but it’s making for a really long render time so I haven’t seen the final result yet. I’ll share the results when I do. Thanks!
I’m having a similar problem at the moment. The only light that is working for me is ambient. I am trying to light an extruded shape layer along with regular layers staggered in z-space. “accepts light” is on in material options. I’m stumped.
