Hi All In the developer documentation it states that the front of a loco or wagon has to be facing in the Y axis direction which seems counter intuitive when modelling and I couldnt work out why until I opened one of the developer examples, the Max file I looked at uses a left handed gizmo but my Ive only ever known the gizmo to be right handed. The wagon itself is facing the same way but with the RH gizmo the Y axis now becomes the X axis, does anyone know if this matters at all? I ask because the documents also state that the wheels must rotate around the X axis which would work with a LH gizmo but with a RH gizmo the will rotate around the Y axis. Thanks
