Seriously, there are things missing in the demo that make it a bit frustrating trying certain tutorials. So far, I've only found one, but it's a stinker: Parent in Place isn't there. Choosing the "Parent Items" block, one is presented with a thin, empty block, minus the expected buttons (as seen in the docs). Also, I checked "messiah_log.txt", and it complained of two missing files, "commands.ccd" and "key_assignments.kas".
These minor foibles didn't dissuade me from ordering, but who knows about the next guy. The parent items bug is rather grating, since I was attempting to convert a rather irksome BVH file which refused to import correctly without an extra null for each bone present.
