    RH to LH coordinate system conversion

    Hi,

    I have some trouble importing Collada models into a left-handed coordinate system (DirectX)!
    As long as the nodes have only <translate> and <rotate> elements I have to invert the z position and the rotation on x and y axis.
    In this case the models seems to import correctly.
    But what do I have to do if the nodes are transformed by a matrix?

    Best Regards

    In all cases (<matrix>, <translate>, <rotate>, etc) you want to transpose the matrix representing the transform.
