limit to visibility checking by bounding box
« on: May 06, 2021, 08:39:54 AM »
Hi,
this is just idea for improvement. Its a long time FP problem, when you use Limit to camera visibility. Its a bit useless when camera moving verticaly becase checking of visibility is done from pivot and not from bounding box. Imagine you have tall trees, so the height exceeds default 15% extend and the trees starting to popup or disappear. Increasing extend is not a solution because then is unnecessarily big and its no point to use it anymore. So the solution is checking the visibility by bounding box.

Would You please a create simple max scene to illustrate the problem ?

Here it is. As you can see camera is moving up and the boxes should be visible all the time.But because the checking is done on pivot level they disappearing.

There is a back Offset parameter to bring them back.
Maybe in some distant future version this can get some attention, if gets requested more.

Aaaah, never touch this one. But anyway this could be problem with long lenses, so checking by bounding box will be always better.
Thanks.
