We have the same issue with forest pack camera clipping.
We use special 3ds max mode called 'headless' which does not have any interface.
When objects in a scene are set 'auto assign to active view' option in camera setting and we switched camera view by script, forest pack is not able to figure out that we have change camera, and do not update clipping settings.
Probably Forest pack take this information directly from user interface of 3ds max, but on our configuration it does not hapend at all, becouse in headless mode there is no interface.
Have you any solution?
