Hi there,

I'm using blender 2.49b to import multiple animation files that are in a different file format. I found a script to import these animations but it constantly writes over my previous animation. Any help would be awesome, thanks.

Here's the excerpt of code I believe is giving the problem:

Code:

action_name = Blender.sys.basename(file_object.name) action_name = action_name[0:action_name.find('.')] action = Blender.Armature.NLA.NewAction(action_name) action.setActive(armature_object) for x in xrange(mesh_count):      read_mesh_transformations(file_object, version, armature_object) def ani_read_mesh_transformations(file_object, version, armature_object):     key_frames = {}     armature_pose = armature_object.getPose()     armature_pose_bones = armature_pose.bones     mesh_name = file_object.read(40)     mesh_name = mesh_name[0:mesh_name.find('\0')]     mesh_name = elu_to_blender_name(mesh_name)     print "transform %s start 0x%x" % (mesh_name, file_object.tell() - 44)     pm = struct.unpack('<16f', file_object.read(64))     pose_matrix = Blender.Mathutils.Matrix([pm[0], pm[2], pm[1], pm[3]], \                                            [pm[8], pm[10], pm[9], pm[11]], \                                            [pm[4], pm[6], pm[5], pm[7]], \                                            [pm[12], pm[14], pm[13], pm[15]])     translation_count = struct.unpack('<I', file_object.read(4))[0] #    print "translation count %d" % translation_count     for x in xrange(translation_count):         tx, ty, tz = struct.unpack('<3f', file_object.read(12))         translation = Blender.Mathutils.Vector(tx, tz, ty)         key_frame_second = int(struct.unpack('<I', file_object.read(4))[0] / 60)         translation_matrix = Blender.Mathutils.TranslationMatrix(translation)         key_frames[key_frame_second] = translation_matrix     rotation_count = struct.unpack('<I', file_object.read(4))[0] #    print "rotation count %d" % rotation_count     for x in xrange(rotation_count):         rotation_matrix = Blender.Mathutils.Matrix()         rotation_matrix.identity()         rx, ry, rz, rw = struct.unpack('<4f', file_object.read(16))         if version >= 0x1003:             rotation = Blender.Mathutils.Quaternion(-rw, rx, rz, ry)             rotation_matrix *= rotation.toMatrix().resize4x4()         else:             rotation = Blender.Mathutils.Quaternion([rx, rz, ry], math.degrees(-rw))             rotation_matrix *= rotation.toMatrix().resize4x4()         key_frame_second = int(struct.unpack('<I', file_object.read(4))[0] / 60)         if key_frame_second in key_frames:             key_frames[key_frame_second] = rotation_matrix * key_frames[key_frame_second]         else:             parent_inverse_pose_matrix = Blender.Mathutils.Matrix()             parent_inverse_pose_matrix.identity()             if mesh_name in armature_pose_bones.keys():                 if armature_pose_bones[mesh_name].parent is not None:                     parent_inverse_pose_matrix *= armature_pose_bones[mesh_name].parent.poseMatrix.copy()             parent_inverse_pose_matrix.invert()             key_frames[key_frame_second] = rotation_matrix * Blender.Mathutils.TranslationMatrix((pose_matrix * parent_inverse_pose_matrix).translationPart())     if mesh_name in armature_pose_bones.keys():         if len(key_frames) > 0:             for key_frame_second, key_frame_transformation in key_frames.iteritems():                 if armature_pose_bones[mesh_name].parent is not None:                     key_frame_transformation *= armature_pose_bones[mesh_name].parent.poseMatrix.copy()                 armature_pose_bones[mesh_name].poseMatrix = key_frame_transformation                 armature_pose.update()                 armature_pose_bones[mesh_name].insertKey(armature_object, key_frame_second + 1)             armature_pose_bones[mesh_name].poseMatrix = pose_matrix             armature_pose.update()         else:             armature_pose_bones[mesh_name].poseMatrix = pose_matrix             armature_pose.update()             armature_pose_bones[mesh_name].insertKey(armature_object, 1)
