    Hi people,

    my object has different modes for it's visual represenation. If I use a polygonal mode everything works fine. But as soon as I switch to a mode, where I only use the drawing function and activate the "Render Instance" option it becomes invisible.
    I tried the same with the default Joint Object (which is represented as a circle) and there the instance object is displyed properly. So I assume I am missing something or doing something wrong.

    I would appreciate any help :)
    Greetz,
    Satara

    If you haven't already, try to return an empty Polygon Object instead of NULL.

    I'm only returning NULL if something fails. In the mode I mentioned GetVirtualObjects returns a PolygonObject which contains two points to have the proper boundings for drawing. So that's not the problem :-\

    If someone ever runs into the same problem.. A workaround is to draw the objects from a scenehook traversing the whole scene and checking if the contained instances are render instances and are referecing to your object.
