Simon Edmondson Posted March 11, 2010 Share Posted March 11, 2010 I have a figure lifting boxes out of the back of a van and wondered if anybody could advise as to which was the best setup for the o constraints ? The box to the figures hand or hands, The hands to the box, and which would be the best constraints to use? The figure is lifting the box up, turning through 90 degree then walking off to the side, carrying the box ? regards simon Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted March 11, 2010 Hash Fellow Share Posted March 11, 2010 The figure is lifting the box up, turning through 90 degree then walking off to the side, carrying the box ? For that specific scenario... While picking up the box I'd constrain the hands to the box and then animate the box as if the hands were moving it. (Of course, you may need to unconstrain and reposition the hands a few times before they get to their final gripping position on the box) While carrying the box, leave the hands constrained to the box, and constrain the box to some bone in the chest, like a spine or torso bone. This eliminates having to animate the box moving through space ahead of the body. You can still vary the box's position relative to the body to make it seem not rigidly glued to the chest. In all cases make sure you are constraining with actual geometry bones and not merely the controller that influences those geometry bones.

Simon Edmondson Posted March 11, 2010 Author Share Posted March 11, 2010 Rob Thank you very much for that. Could I ask a supplemental question? Which constraints would you suggest using ? I tried Translate for the hand but it detatched from the rig and adhered to the box. Orient like was a bit way ward and kinematic caused all sorts of 'wobbles " ? regards simon Quote Link to comment Share on other sites More sharing options...

I made a mistake on the hand part... constrain the hand controllers to the box not a hand geometry bone (because the hand controller is what tells the hand geometry bone where to be.) This will be the IK hand controller and your arms will need to be set to IK of course. You'll need a "translate to" and an "orient like" constraint for each hand. The box does get constrained to a geometry chest bone. And this will be a "translate to" and an "orient like" constraint. What these bones are called depends on your rig. In some rigs the IK arm target only positions the wrist but doesn't aim the hand bone, so you'd translate constrain the IK arm target and orient constrain the hand bone Quote Link to comment Share on other sites More sharing options...
Simon Edmondson Posted March 11, 2010 Author Share Posted March 11, 2010 Rob Thank you very much for that. I shall try it out tomorrow ( UK time ). I'm using the rig off the data CD ( 2001 ? ) Thanks again regards simon Quote Link to comment Share on other sites More sharing options...
