Render region hangs up.

[vermu]

Hi,

I have annoying little problem with corona 5. It happens almost in every scene at some point. I can render just fine but when I use render region rendering hangs in preparation phase when you green dots. Does anyone else have this problem?

[romullus]

Sounds like bug. Maybe try to collect minidump and send to the team for investigation. https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006#crashes2

Moving topic to bug reporting board.

Hi,

Please can you provide the Corona, 3ds Max and Windows versions which you are using?

A minidump and the scene would also be helpful, instructions on how to do this are in my signiture.

Thanks,

Rowan

Hello,
we are experiencing the same issues while rendering regions of animation frames in backburner. Rendering freezes for hours during the GI calculations.
It's happening randomly on various nodes but not on every single frames, about 20% of them are freezing. We are using the Max region option in render setup and not the Corona region in the Frame Buffer. Trying out the latter right now to see if that could temporarly solve the problem. I'll update you on our progress.
Issued a ticket to the technical support as well.
Any idea why this happens? thanks

I am using max 2019, corona 5 and win 10. I can't provide minidump cause when the corona hangs up I have to kill max session from task manager. I don't get autodest crash message.

Actually, the page linked to https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max tells you how to get a minidump from a frozen Max that doesn't actually crash ;) Scroll down to "2.

I sent the minidump through support portal.

Hi,

Thanks for sending through the minidump. Would you also be able to provide your scene so we can test it here?

Thanks,

Same for a mate here: region + GI calc -> freeze/hang, not to cancel.

Uploaded "1575887167_Corona-V5-Render-region-GI-Calc-Dump.7z" with another dump if it helps. (Corona v5 | Max 2016 | Win 10)


Good Luck

Hi Frood,

Are you also able to get hold of the scene? It would be a big help for us.

Thanks,

Now I know when the hanging occurs. It's always happening when I convert vray scene to corona scene with scene converter. If the scene is original corona scene it works ok. But if it's converted scene it's never working. But it was working ok in corona 4. This is a bit of a problem for me now.

Hi Rowan,

It would be a big help for us.

I know, but cannot. If you want me to check something specifically in the scene, just tell me.

It's always happening when I convert vray scene to corona scene with scene converter.

Scene was build from scratch, but there might be converted assets inside. But if so, everything would have be prepared externally and then merged. Additionally mate claims that it happens frequently to him (personally I rarely use region).


Good Luck

Hi Frood,

Can you confirm that your colleague is using Max render regions or Corona regions?

Thanks,

Rowan

[Frood]

Native Max region. Thx and

Good Luck

Same here. Not every scene but several - using max region = just sits there calculating secondary bounces forever. Can't send scene though, sorry!
