Armature not posing all of model

Hi all,

I’ve been working on a human model, and I’m having some problems with rigging. I’ve followed a tutorial which says to separate by loose parts, then to parent the model to the armature with automatic weights. However, when I do this, I still get the error message ‘Bone Heat Weighting: failed to find a solution for one or more bones’. After this, when I try to pose the model, I get errors in two areas:

  • The hat moves with the head, but the nose stays in place, and different parts of the ears move different amounts.
  • Most of the boots are moved with the leg, but some parts are left behind.

In both of the above cases, the parts that move and the parts that stay are part of the same mesh. I can’t understand why they’re moving differently.

I’ve also tried uploading a copy of the .blend file, but it just tells me I don’t have permission to do so.
