I thought I could solve the cross-talk problem by altering the master name in the cr2 in a TE and then opening it in Poser. It did not work for me, when I actually tested the result. Whatever Poser does to make a second figure in figure 2 , even when it is figure one in the library file it was taken from, probably causes it to erase the TE changes in the master slots. That is my guess anyway. By using rotations as the masters, I must make provision for cross-talk. But complaining about it because ERC construction morphs are doing it, is complaining about a self-inflicted wound. It is a matter of taking a shortcut and then seeing that it causes problems. It is a matter of trying to drive the whole assembly plant down the road, rather than a car that comes from the plant, and wondering why it is too wide for the road.
