Slow Render Times

Deke

I've rendered other angles from the same scene and they render in about a minute or two. One angle however is super slow and I'm getting a couple notes in the render box:

premature call to rimotionend
invalid bounding box for primitive

this is on a mac in Daz Studio. It is a scene with UberEnvironment2 installed (it was part of a lighting preset that I like). Any thoughts on how to speed this up?
