Viewport problem with corona camera - 3dsMax

Hello,
I searched everywhere about this problem but I didn’t find any solution.
Corona camera was fine and everything was OK, when I closed the file and reopened it again I found that the camera viewport shows nothing.
When I render everything seems OK, But I can’t see anything in viewport.
I tried to orbit it, but it shows only gray.

Any help?


Hi,
Things that i would check first - camera clipping, viewport clipping. If those things aren’t the issue, then try to create new camera and see if that helps.

Thank you very much.
It was camera clipping, Once I enabled this option everything becomes fine again.
But I didn’t mess with that option or any camera options While I’m working.
Thank you again.

maybe you have wrong scale in scene

Be careful when merging or importing assets/scenes from 3rd parties, many times you will find that randomly some scene settings are being messed up.
