To begin with, just change one matrix, eg rotate the shoulder of one arm 90 degrees. Is it parenting the rest of the arm, is it rotating correctly etc.

Secondly, I recommend having a debug avatar that is drawn just as spheres or sprites at the bone heads. There are no rotations applied. This will quickly pick up problems like:

Row vs column error

Z up vs y up error

Skeleton scaled, or rotated differently to skin.


With FBX, I've had problems where Blender exports the mesh and armature with different up's and you need to know which matrix to apply as you build the mesh to correct it. This is why I now only use collada, I have more visibility of what's going on.

How do you calculate the quaternion? Do you have a yaw pitch roll to quaternion function or something? Secondly, are all the other joints parenting the hip rotation? If so, the rotation of the hips shouldn't make the pose twisted as it's the root.

Engines by their nature, in computing and every other technology, become obsolete. I cant even pass my height maps and meshes straight over to physx in compute, let alone run a moba server that streams to compute on a gpu blade server where the cpu is just a marshaller. With regard to unity etc they are all limited in so many ways, just pick a topic and there are a dozen things they could do better. Its not their fault, you can be everything for all platforms without losing something. I guess people used to using others engines just cant think outside the boxes they sit in.

Just give me a day to make some pictures so you can see
