There is one very annoying property to my plugin that should be resolved prior to beta-testing. It involves my plugin hierarchy modifier objects (bones) which use ModifyObject() and the bounding box for the PolygonObject that they deform. In the case of my modifiers, transformations of the root bone are done to the bone which seems to cause this dislocation of the PolygonObject and its bounding box. This wouldn't really matter much except that Editor display clipping seems to be using the bounding box. When the bounding box goes out of the display, the PolygonObject, although fully in the display, disappears.
I guess one solution may be to always translate/scale/rotate the PolygonObject for the root bone. Is there something missing or a technique that should be employed to keep the bounding box up to date and properly aligned with the deformed PolygonObject (noting that, yes, I am calling polyobject->Message(MSG_UPDATE))?

Hmmm, I'm implementing GetDimension() as I write this, but am thinking that the updated bounding must be calculated during the ModifyObject() call (on the 'op' deformed-copy of the PolygonObject). Is that correct?

Okay, so just implementing GetDimension() and bounding my modifier objects is enough to stop the vanishing PolygonObject.

ah, have just seen this thread. First of all, great you managed it yourself second, great to hear this as I had the exact same problem but never got around it checking what the problem was. So thanks for clearing this up!
