Hi Bal, I'm not an animation expert, but I think you can easily achieve this by using Parameters Wiring, and linking the source single axis parameter to the target object axis parameter. Remember to Freeze Transforms to zero before doing any actual rigging. Another way, is to use a Script Controller on the single target…
Nope...sadly there is no Orientation Constraint for a single axis in Max...but Script/Expression Controllers, Parameter Wiring or Reaction Manager can do this quite good...not as fast as setting up a constraint, though...if you want to learn about rigging in Max, get Paul Neales DVDs from CGAcademy...even if you know your…
