I had set up a rig for a character. But i move the bones of the hand(I used IK solver for the hand setup), the mesh moved as well, only that the bones seems to move out of the mesh.
How do i correct this problem? thanks
There are a host of possible reasons for what you described. You may want to describe your situation in more detail.
In any case, the universal “always ask” questions when dealing with weird rigging errors.
If you have rigged your character manually with vertex groups, make sure that all vertices are assigned to the correct group.
If you have used envelopes, check to make sure that all vertices have appropriate weights on them. If you make your envelopes too small, its possible that some vertices will be assigned a weight of 0 for all bones and will not move with the armature.
Finally, especially with envelopes, check to make sure that bones are only influencing the correct vertices. Often, in meshes like hands and feet, an envelope;s region will extend over something it should not, such as a neighboring finger. Manually paint out incorrect weights to zero.
could be one or a combination of the above.
hope that helps
