Thanks for the advice guys.

yeah I use 3dx5 mostly to import my FBX files simply for the wider compatibility and ability to have 6 open as well and work between the two on FBX import exports.
I can this way make my CC characters props with perform motions too.

"To define Tao is to defile it" - Lao Tzu

I wish someone would share a trick, a way, to open two 3DX at once.
Why?
Often I add new sliders (deformers) for the Expression Editor to a character.
But you get an error message if you try to open saved values of the original character with a different amount of adjustments.
I thought a solution would be to transfer values quickly between both old and new using cut and paste of values with 2 3DX open at the same time.
