Script para bakear actions, escrito por vladius para Blender:
(viene de este hilo).

Código:

#.Bpy. Name: bake active action. Blender: 242a. Group: object. Toltip: bake constraints todo action keys. _author__ = vladius. _url__ = [vladius, fanatic, ru"] _versión__ = 1.0. _bpydoc__ = \ Action bake let you bake the current object action constraints todo normal action keys. Usage: Select an object with an active action, and select bake active action from the object->scripts. Menú of the 3d view. From Blender import * From Blender import types. Import Sys.
