I need to convert animation from Unity to 3ds max, but there are different coordinate systems.

I wrote a method. Where I made a mistake? Please help

public static Quaternion ConvertRotation(Vector3 rotation) {
    Vector3 flip = new Vector3(rotation.z, -rotation.x, -rotation.y);
        Quaternion qx = Quaternion.AngleAxis(flip.x, Vector3.left);
        Quaternion qy = Quaternion.AngleAxis(flip.y, Vector3.forward);
        Quaternion qz = Quaternion.AngleAxis(flip.z, Vector3.up);
        Quaternion qq = qx * qy * qz;
        return qq;
}

  • I thought all you needed to do in 3ds max was rotate 90° along the X axis and set Y as up. Also you should describe in more detail what you're trying to achieve and why your code isn't working – TioneB Jul 09 '23 at 20:40
