So i tried using smooth bind in maya and some parts of my character model are stretching. Does anyone have any tips or good settings in maya that will work well with smooth bind? I'm using maya 2015 if that's helpful

if it's a character model you're rigging, you're gonna have to paint the verts. if it's a weapon model and the parts like the clip stretches while being moved, you need to use the settings on the screenshot below.

Click the square box beside the smooth bind option.
Make sure its only binding to selected joints and not the entire skeleton. tri only has 3 points that could drive its direction, so set 3 joints max influence. You may need to change the other setting too depending on what your doing.

If it doesnt work you could manually look at the weights by selecting the mesh and clicking...skin... edit smooth skin..... "paint weights tool".
Then scroll through the joints and look for tag_origin or tag sync or any unnecessary joint and make sure they have zero weight, then remove them from the bind by selecting the joint and mesh and clicking edit smooth skin...."remove influence"
