Okay, here is what I've been experiencing. The dress works fine in P5 right up until I go to render it. Then P5 just locks up and does the "not responding" thing. It doesn't do that for anything else. I've slowly eliminated everything and narrowed it down to the dress. I bring in the dress and nothing else and it locks up. Weird. I have the dress installed in a seperate runtime that I've set up for all my V3, GV, IV, and SP stuff. The dress is the only thing that doesn't work when pulled from this runtime. However, I installed the dress to my old, bloated P4 runtime and it rendered fine in Propack. It also rendered fine in P5 suddenly, but only when pulled from the old P4 runtime. I'm going to try seeing if it will now pull from the new seperate runtime now that P5 can choose to reference it from the P4 runtime if it wants. I've noticed that P5 likes some obj's to be referenced in the old P4 runtime or P5's own runtime. Why is that? Anyone know? Anyways it's working now, finally. This is a relief, because I was hoping to make P5 friendly mat pose files with the node info in them and all that.
