I cannot access your code so I cant give you the solution to your problem.


Simply for each bone you must compute the absolute transform matrix.

Before you transform the vertex position you must *move* the vertex to the bone space (just by using the (Inverse)BindTransformMatrix(this thing here is a floating notion).

And after that you can transform the model to the world space.




About that line


joints.skinning_matrix = MatrixMultiply(joints.inverse_bind_pose_matrix, joints ...


I'm not sure what is going on but it seems like you are multiplying the parent bone inverse_bind_pose_matrix, to each child bone in the hierarchy. I don't know how the data is stored, but double check your code.
