So,

The wheel is modeled as a separate part and imported in poser then I parented it to the body of my 4wd.

In 3ds max, I set the axis as a local one the I had to change it again in poser using the display origin as shown in the 4th pic.

And that's all I can do... Should I change something before, later or in .pp2 ? It can be that difficult :(

BTW what is the joint editor ? Can it help me ^--^ ?

Thank you,

SAM
