Hi Craig,
Good question. The Admin team hasn’t adjusted its rating, so r11 and up. How can you be sure that this is always updated, given the amount of tutorials that would have the need to be evaluated with each release, to be on track with that?
My suggestion, if in doubt, download (if available) the last version of the scene files and open it. If you get already a warning during the open-process, be careful. (Not a big help here, but hopefully it helps to prevent time wasting on your side)
So, of course, I follow my tip. I went to 5b and downloaded the file. Opened it and selected the controller. On the end this is what counts, right? I couldn’t find a problem, here. (Eyes and tongue are not in place so far, but is that a deal-breaker?) Please replace the HyperNURBS, if it cause problems (The old one did here). ;o)
The “Pose-Mixer” went into the “Pose-Morph” (after R12), but no problem to work with it now—have a look into file 5b, and you see how it is working now.
If my memory serves me well, this was the series that lead to the Character Tool as we have it now in R16 for example. Bret was certainly leading this development a lot. So, this series has serious content stored in it, which might help even to understand the roots better of later development (just my perspective).
I hope that helps.
My best wishes.
