It basically clips/disappears randomly when you go too far. Not really sure what causes that. The rectangle should stay the same no matter how far you are, unless the maximal distance for visibility limits you so.
Ye, that seems to fix this particular issue. However, that then breaks the auto-scaling, or zooming basically. The further you go, the bigger the BillboardGui basically is. What can I do to fix both of these issues at the same time?
