heyas; dave, did you look at the figure options and properties and such? this shouldn't be a problem, but there's a property under p5 that is 'visible in ray tracing.' if this is unchecked (it should be checked on the stuff you are using, but who knows what happened), then things won't appear in the ray tracing. now, (also supposedly) this should only affect reflections and maybe shadows. that is, i THINK it is supposed to render the object but not its reflection, when that option is un-checked. well, it's a long shot, but it's a thought. i had something like this happen to me just yesterday. i had a render lockup (and this was in p4), and i did a save, and imported the pz3 back into poser (to prevent that endless render bug), and one prop would NOT render. it was very strange. but when i replaced it, it worked. which is also probably no help. :/
