I animated this guy in Unity with cinema-suite.com’s kinect software. He loads at 0,0,0 but on animate jumps -13 y and -1 x, anybody
know how to make him start at 0,0,0? His ‘dot’ remains at 0,0,0. Using 2.69

Your animation is offset.
If you look at z loc fcurves for the HIP bone you will see this. (image)
*Image Below shows x and y… later I noticed you had rot x = 90 and scale = 0.1, hence moving z.
To correct,
select the frame you want to be at 0,0
select the hip in pose mode, and note its z location. It’s around 138 at frame 1, not 13 since the animation is scaled to match the scale of the armature.
In the graph editor, select the z loc and move it to zero. To move it down use gy-138
Currently I’m working on a number of scripts to use with bvh files.
Here is a test script to rescale the animation and apply scale to rig.
import bpy
def rescale(rig, action):
axes = [0, 1, 2]
for axis in axes:
scale_factor = rig.scale[axis]
# get all the coord points that are locs
cos = [kp.co for f in action.fcurves if f.array_index == axis and f.data_path.endswith('location') for kp in f.keyframe_points ]
for co in cos:
co[1] *= scale_factor
bpy.ops.object.transform_apply(scale=True)
class SimpleOperator(bpy.types.Operator):
"""Tooltip"""
bl_idname = "object.simple_operator"
bl_label = "Simple Object Operator"
@classmethod
def poll(cls, context):
return context.active_object is not None
def execute(self, context):
rig = context.object
action = rig.animation_data.action
rescale(rig, action)
return {'FINISHED'}
def register():
bpy.utils.register_class(SimpleOperator)
def unregister():
bpy.utils.unregister_class(SimpleOperator)
if __name__ == "__main__":
register()
# test call
bpy.ops.object.simple_operator()
I suggest you use the global scale factor when you import bvh. Non unit scales can be a real hassle later down the line.
