This (shadow issue) is very much related to a discussion I was having in an earlier thread, where the problem with casting depth map shadows (after deleting existing lights) was identified as being related to the fact that neither Poser 5 or Poser 6 default light sets include shadow cameras. It is indeed possible to render depth map shadows when using Diffuse IBL lighting (just like any other light?) if a shadow camera is present for the light. I'd love to hear some definitive clarification about whether the issue with Diffuse IBL being discussed here is specific to IBL, or is merely just another symptom of a more general problem that applies to all light sets without shadow cams. Surely after all this time CL must be aware that the default light sets in P5 are missing shadow cameras? If the ability to render depth map shadows is simply attainable by including shadow cameras with the light sets, then why have we all waiting so long for such a fix? Might there be more complex reasons why CL decided to (continue to) exclude shadow cams with the light sets in P6?
