[kalishbg]

Hi guys,
I have issue with corona sun and cameras and. They just disappeared, only corona camera targets stayed in scene. When I try to create new camera it create Corona camera 4, but now 1. It means they are somewhere there but like they vanished! Anyone who experienced this or anyone who can help me with this? Itoo forest disappeared from scene as well.

What exactly happened before the objects disappeared? Did you save the scene, or saved and opened it? Did you import or merge some objects into your scene?

What I remember is that I had imported a CAD drawing with xref internaly. Not really sure what have happened.

Did you check obvious things, like hidden layers, visibility filters, etc?
