I've decompiled judy's model and found string in a code "$Animation "a_proportions"" that includes param "subtract "a_proportions" 0". This string addressing to sequence "a_proportions.smd" but in it i've seen just bones in a plane moved below ground. I think you got bones in state like this by some operation I can't guess. Can you tell me how did you made "a_proportions.smd"?
