Poser gets tired after being asked to manage and remember lots of variables. When it gets fatigued from having to juggle stuff, like us, it makes mistakes and forgets things. My Guess is it didn't render because it was at the end of a high resource session. When this happens, you must restart Poser. If you save the file, you will ruin your scene file by simply saving all the mistakes. If you are making Poser juggle tons of resources, save and restart poser every few hours. Let it take a quicki break, rest it's eyes and start fresh, even if it is only for 10 seconds.
