Hi. For a start you should turn off expose in the environment panel, and only use Coronas exposure control. Right now you're using two exposure controls.

Hope it helps

I don't know what you mean by "nothing", but I noticed that you have set Coronas white balance to 1500. Try resetting it to default and see what happens.

BTW: The environment is set to "Corona", but the map in this slot is not the same as shown in the material editor on the first picture. So check if the map used is set up correct. Besides that - if you're using a physical camera, then try using perspective or a standard cam until you've found the source of the problem.

Hope it helps

Render Setup > Scene > Render selected: Object GBuffer id. Just disable render selected option. :)

I had this problem randomly occur today. Sky was black if viewed directly... tho it was visible in reflections and refraction. Had to revert to an earlier autosave as I could not work out the problem.

@jjduncs, is it possible that you had direct enviroment override accidentally  ticked?

Do you mean the 'Direct Visibility Override' in the Scene environment setting? I thought I might have changed it too, but checked and it wasnt the case. I then intentionally ticked it and put a coronasky map in to see if it would be visible but it still rendered black.

Hi,

Is your problem solved now or you are still looking for solution. If you are still looking for solution then do let us know your 3dsmax and corona version you are using.

If you can share your scene file for close inspection that would be great. You can share your files using our private uploader. Here is the link: "https://corona-renderer.com/upload"

After you have uploaded your file, do let me know the name of the file.

Thanks.

Regards,
Avi
