I've got a scene lit by HDRI, emitting light, but no photons. I've keyframed the rotation on my HDRI sphere so it gently turns and produces a sunrise. When I render individual frames I can see my light changing. However when I batch the whole thing nothing happens and my light stays static.
I've tried Gi as well with rebuild photon map checked, -but no difference.
How can I get maya to recognize that I am turning my sphere.
any help much appreciated
