you can either send me the model for rigging , or I can step you through it an easy way.

One easy way is to seperate your ibj file into parts. so base, pivot, arm1, arm2, cyl2 and cyl 1.

Import them all to Poser and use hierarchy editor to arrange as

1. Base

        2. cyl1

        2. arm1

              3. Cyl2

              3 arm2

Then use the button near the bottom to create a figure.

Then load the figure and using the joint editor set the center (pivot point) for each part

You need a script to unhide the x,y,z tran dials or just edit the cr2.

final step is to set cyl 1 and cyl 2 to point at each other so they make a working hydraulic ram.

 

If you want me to rig it send it to marks542004@yahoo.com with renderosity in the subject (or it goes to my spam folder)
