Hi everybody,

As one as my first Maya projects (I'm a newbie) I have rigged a simple teddy bear (see the attached picture).
I have binded it (smooth bind, Bind to Joint hierarchy).
Now when I move an arm, there is deformation in the head and the belly (see the picture).
Also when I move a leg there is unnatural deformation in the belly.
I'm trying to get rid of this deformation for a couple of days now and I have tried all the bind options but I won't succeed.
Can anybody give me some advice what to do?

Adjustable influence distance

What I'm looking for is some kind of "adjustable influence distance".
So for example that you can set an influence distance from the leg and beyond that distance, there is no influence anymore.
Is that possible in Maya?

Auto weighting (the result you get when you do a smooth bind) is almost never 100% perfect, you need to edit the weights to refine the deformations by painting them or using the component editor etc

You can adjust the influence more interactively if you use the Interactive Bind which has capsules you adjust to control the falloff but weight painting is usually needed to get things 100% no matter what way you bind.

Ok, thanks.

With the help of your reply I found a tutorial about skin weight.
Now I know how it works with weight painting.

On another note, when you are binding, what value do you have in max influences? Is it the default 5? I like setting it to either 2 or 3.

If you have it set to 5, each vert will take a value from 5 joints, most likely the closest joints around. Since 5 is such a big number that's probably why you have weights in your head and stomach area reaching out to joints so far away.

Indeed, the value in max influences was too high.
I choose a lower value and it's better but still need to edit the weights.

Thank you.
