Apologies if this has been asked, but I couldn't find it anywhere. I'm using Blender 2.49b to change some head meshes for Morrowind, and they're already animated. The lips move and the eyes blink. I'm editing the neck, but every time I do and back out of edit mode, the changes revert. I figured the animations had something to do with it. Any help would be appreciated.
Various Explanations for the behaviour. Incomplete list follows.
Shape Keys. If there are multiple Shape Keys present, then you may end up editing a shape key whose influence is zero 0 or close to zero. Blinking eyes could be done with various animation techniques including shape keys.
Modifiers. Shrink Wrap or Armature modifier can change the mesh shape. That is the purpose of such modifiers. For example small edits might be completely dominated by a Shrink Wrap Modifier and thus not visible.
