VFB all black

hello

since last week I get the same result when I try to render an image (which I’ve rendered many timees before) i get completely black VFB and 0,0% noise.

I know my scene is heavy and I have some missing assets but this never happened before, under similar circumstances (the only thing I added were decals and a concrete texture to one of the pillars).

can someone help?
Alreday restarted everything but still gives this same error. what can I do?

thank you

Could it be that you have render selected enabled without any valid selection? You can check it in render setup > scene tab.

on render selection the mode is disabled

Did you check if there’s any lights in your scene and if they’re not hidden, or disabled?

the lights are all on, I have corona sun. I did the image below last week (on tuesday.) it stopped working (black VFB) after that.


now I changed the camera and it started working. but the other camera still all black.

have you accidentally turned on clipping for the camera? is there anything infront of the camera that might not be obvious? i.e. a plane acting as a bounce card or backplate for another camera that is set to display as box?

big mystery. I changed to camera 2, when I got back to camera 1 it was working again. didn’t change anything else.

thank you anyways!!

If it ever happens again and gets fixed by switching to a different camera, please show your problematic camera’s settings. Maybe there will be some hint there.
Also, feel free to share your scene with our support team at https://support.chaos.com/hc/en-us/requests/new

Corona cameras sometimes get Target Distance to 0, change that and it will work.
