Hi Jeff,
I can't help on this because I have no experience on quaternion and Euler angles (even though I suppose soon or later i will have to dig a bit into them...).
Sorry.

Jeff? (maybe this is a meme or language thing like Jack?)
I am learning quaternions via internet. A good way to experiment with them is to use Unity as they are heavily integrated.
Never mind the latest question about world space. It seem you can get the world space quaternion by multiply all local quaternions from root to the local object. Ex: root quaternion*hips rotation*spine quaternion...
So no update is needed it seems :-)

I will call you TAK (The Any Key) ...
Cheers

Hi The-any-Key, You can use the "RINode.WorldTransform()" API to get bone's world quaternions. This API is already in the latest development version (2/1/2019). ------------------------------------------------------------------------------------------------------------- You can try this code: import RLPy avatar_list = RLPy.RScene.GetAvatars() avatar = avatar_list[0] bone_compoment = avatar.GetSkeletonComponent() skin_bones = bone_compoment.GetSkinBones() for bone in skin_bones: world_transform = bone.WorldTransform() world_q = world_transform.R() print( world_q.X() ) print( world_q.Y() ) print( world_q.Z() ) print( world_q.W() )

Thanks. But I already tested that. And it seem the values returned from the WorldTransform are wrong (filed a bug ticket)
Ex if I have a prop or bone with Euler rotation [90,0,0] (x,y,z) with no parent I should get the quaternion [0.707,0,0,0.707] (x,y,z,w). But I get [0.85,0,0,0.53] aka [116,0,0] (x,y,z)
