Max 2022, Vray 5, forest pack pro 7.1.1,
With the system above, Forest will completely disappear from the viewports and the only way to see them again is to re-open the max scene.
In the UI, forest is not locked to camera, has enough display items in the viewport. etc
This has only happened since i upgraded to max 2022. Max 2019 was fine.
Any thoughts on what could be causing this and how to rectify it.
