Title: RC7 - Black pixels (Urgent please)
Post by: Dionysios.TS on 2017-10-11, 12:23:08
Hi all, I have a big problem, first time since I use Corona, I produced an image in DR which I I found ready this morning but has a lot of black pixels everywhere!

In local I didn't noticed any problem yesterday, while I was doing a lot of tests but I don't understand what is wrong with the final version...
I used RC7 and saved in Corona CRX format.

I include a crop sample as well.

Thanks!!!

Can you do a quick test with no bloom and glare and no denoising?

The setup had no denoise in any case.
As for the bloom and glare, now I am going to render it again and turn it off. I'll turn it on later in Corona Image Editor and I'll let you know.
Only issue the image needs 6 hours to be rendered...

Thanks for getting back.

IMHO this doesn't seem like something B&G would do.

Do you use portals by any chance?

No portals at all.

I made a crop render in local and have no issues... Don't know if is a DR problem or anything else at this point.

I use RC8 no btw.

Bloom and glare was a random shot from me, because I remember a similar issue with it from some time ago.

There is a slightly similar issue reported by me in our internal tracker, named "1.7 RC7 - black vfb issue" - could you look into it?

Final rendering now is ok.
6100px x 6100px  - RC8

No black pixels produced.
I don't know if this helped but I turned off the bloom and glare effects and turn them back on Corona Image Editor.

If you would have time for this, could you check if the black pixels come back if you enabled bloom and glare again?
