I was wondering if anyone can help with a problem I've been having with trying to apply to a Subdivision Modifier to a model that I've been working on for a while.
I asked about this problem on another website, but since this site deals with the more technical elements of Blender I thought that I would have a greater chance of getting help here with this problem than somewhere else.
Anyways, I had been trying to fix some problematic geometry on the lower area of my model's belly but since I had been trying to keep amount of overall amount of vertices to a minimum, there was a insufficient amount of geometry to work with in fixing the issue. I then decided to try and apply the Mirror & Subdivision modifiers to the model so that I could increase of amount of vertices to work with and then use the Sculpting Tools to smooth out the problematic area. It worked as I intended, however, it is here where the main problem of this topic comes into play.
After the Subdivision Modifier is applied, everything seems fine at first but when I try to pose my model, various distortions in the mesh that weren't present before I applied the modifier begin to appear all across it.
The problem is especially noticeable here with the underside of the model, with a really nasty-looking, sharp corner forming on the back of the foot/leg that shouldn't be there.
Surely, there must be a way that the Subdivision Modifier can be applied so that it doesn't cause these distortions. Otherwise it makes the Subdivision Modifier a rather unreliable tool to rely upon, since you have no idea how the model & the way its rigged is going to turn out when you apply it.
I've included a Blend File that contains a version of the model without any of modifiers applied and without any rigging. I hope that someone will be able to help me out with this issue, and that any aid whatsoever would be greatly appreciated.
