Batch render saves totally black hdri images

[mitviz]

i basically set batch render in 3ds max up and left it to render based on a time limit, i saves all the other render elements out correct but not the beauty, is there something extra to do that i missed? i have been using batch render for years but first time with corona

It should work fine, however I remember some similar cases. I will look for a solution, but please tell me:
-in what file format are you saving the beauty and other elements?
-can you try removing all elements and then re-adding them, and also re-adding the path to the beauty output?

i save always as hdri file and i can try that approach

[maru]

Can you try with exr?

[mitviz]

i can try exr but usually if its exterior exr doesnt save my background so i try to avoid it

[mitviz]

yeah exr seems to do the trick, why it doesn't work for hdri though?

[mitviz]

since EXR works can i resume render from these saved exrs?

AFAIK there is a bug in 3ds Max and HDRs saved with specific settings are broken. Could you revert to the settings which you used previously and try with a different renderer? (even scanline)

You cannot resume from a "regular" exr. Here is why: https://coronarenderer.freshdesk.com/support/solutions/articles/5000501975

o ok, for vray which i use i know it works because i use it all the time so i think it might be something with corona
