Very good, dodger. It's nice to have all this info in one place for a change. I have it all scattered in various docs (by VK, Anthony Hernandez, etc). Plus, you've cleared up a few things that puzzled me. A couple of points. 'The mysterious storageOffset directive' I also messed around with this, thinking naively, that I might be able to move an externally referenced obj for a figure in poser space, without going to the hassle of moving every part of the assembled pieces one by one. No such luck. The damned thing doesn't make a hoot of difference. Pity... 'uniqueInterp' If this does mean only use integers, would this force MTs to jump from 0 to 1? I must try this. It could be useful for some things. 'trackingScale: The sensitivity of the dial. .04 is a good value for a geomChan dial.' Hmmm...Pity that no matter what you do, the tracking for morphs never changes. I'm ready to be corrected here, but I've never yet found a way to force morph tracking. mac PS Maybe you should give this doc to the guy who was compiling cr2 info on his site. I can't find the addy, but I believe he's japanese.
