Quote - The model with these parameter dial slavings seems to work OK in Poser 8 but not in Poser 7. It seems that Poser 7 still has bugs in its morph slaving system.

I don't have P7, I'm a fossil, still using P6. I can vouch from personal experience that the code should work in P5 and P6. P4 had a cross-talk bug, that could affect the correct operation of such code when more than one figure contained the same master channel.

I'm very surprised that this does not seem to be working for you in P7. This stuff is so fundamental that its failure must be considered a very serious bug. I'm also surprised, if this truly is a bug in P7, that I have not heard of it before. True, it is not very often that transform channels get slaving code, but it does happen. Space ships with sliding or folding ramps are an example, as are various undercarriage assemblies on aircraft, and there are a few of these sorts of things around. I'm not doubting what you say. The fact that it works in P8 would seem to be proof that there is no error on your part, and I know that your code will work in P5 and P6, and even in P4 with some caveats. I'm just very surprised that something that works in P6 and P8, does not seem to be working in P7.

I'm guessing that the rebreather is a conforming figure, and I'm wondering if the problem is somehow related to conforming. Have you checked to see if the slaving works when the rebreather is loaded without being conformed?
