Model changes rotation when adding a animation

[hulf]

I'm using the latest build 72dev.

I have a object with a bone parented and a simple animation.
When I'm loading a model with objectloader the rotation, scale and position are fine.

when I add a bone, parent it to the object and load it with objectloader, the object gets rotated ( .x = .y = Math.PI ).

In Blender I tried out some different combinations like suggested in different posts:

• CTRL +A location + rotation on mesh and bone,
• Keep transform - location, rotation
• reset the origin.

Thanks in advance, I hope its not something silly in Blender I forgot.
PS.: Thanks for the great work with three.js, didn't have so much fun in years :).

same issue :) according To Axis Helper axes is messed up
Xbone - bone along axis (Scale etc toggled) All other stuff unboned mesh
here is illustrated example:

last git pull after r72

checked bone export, position of Y coord pos[2] somehow have - sign.

[]bone param fix
io_three/exporter/api/mesh.py
1018 z_axis = -bone_world_pos.y
change to z_axis = bone_world_pos.y
mesh still flipped, probably breaks something in def _pose_bones(armature):
[]rotation fix
XY) rotation problem
io_three/exporter/api/object.py
comment line 381
after line 383 add
yrot = mathutils.Matrix.Rotation(math.pi/1, 4, 'Y')
mesh_node.transform(yrot * obj.matrix_world)

The JSON Blender exporter has been removed with R93 (#14117).
