Ok so the spot lights affects sprite stacked objects and that's it
Viewing post in Lighting not working?
yeah for now only point lights affect sprites. I plan to eventually make sprites interact with spot lights but I couldn't quite get it to look and work right. Does the other lighting work?
Essentially right now sprites use a cheap work around to interact with point lights. Billboards are tricky to get lighting to look correct, and I have yet to find a proper solution (since even a 3d plane rotated around would give weird results as well).
