Modify the length and sound associated to the animation.Modify the direction of movement in Blender.Import an existing animation into Blender.I wrote this tutorial for Oblivion but it works for Fallout 3 as well. In addition to this, in this tutorial I am going to explain how to replace an existing animation with the one we are going to modify, so you won't need the Construction Set or the GECK. This tutorial will explain the main steps involved in this second approach. The second approach is easier because you don't need to worry about things like setting the bone priorities becuase they will be already set in the animation you use as a starting point. You can create character animations from scratch or using existing animations and modifying them. 3.6 Give the finishing touches in NifSkope.3.3 Modify the length and sound associated to the animation.
