Because I don't find the 3dxchange user manual in the Help menu , can some one explain me why the bones leg shift when "active" is enable ?
I would like to convert Spore creatures on non-standard character to use with my Neuron but every time the leg are like "cricket" legs
it's shifting.

Thank for your help

It's the offset for the hips. One of those buttons across the top of characterization panel lets you set it. It defaults to -15.

I played with the hip offset but whatever the value the bone point in front instead of back...

Yuo can try if you want with it

I didn't have any better luck. Maybe try actually putting him in a T-pose? More-or-less. Straighten out the legs and arms.

Thank you Rampa.
I found an alternative. I select the next leg bone wich point in front direction. It could work. This is a draft
of course. The idea is to use the upcoming facial mocap with this kind of characters...
