Hair + Fur Crash

[aaouviz]

Hi,

I'm trying to render an animation which features a static (ie; not moving) hair + fur object.

I have the 'coronahairmod' applied underneath the native max hair fur modifier. I have my settings as "mr prim".

My render would crash every time (either when finished or cancelled) in max 2018. My understanding was that this should not happen in 2020, but now after upgrading to 2020, it is still crashing.

I'm on Corona 5. Windows 7.

Any ideas? Thanks!

EDIT: Max seems to crash in the "cleaning up" task of corona render.

Hmm can you upload an example scene? I've tried to recreate this don't get any crashes. Can you monitor your memory usage when this happens?

And don't forget that the only good thing about a crash is it produces a minidump, which gives us an insight into what was happening and what crashed. Always upload a minidump for a crash :) See https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max

Hi,

Uploaded scene and minidump. Thanks.

I tried debugging without any luck; I turned off displacement. Turned of auto-saving file. Turned off denosing.

No luck. The only thing left for me to try is uninstall 2018 (even though I'm using 2020 for this testing).

Do you have user name non English? Hair do not like non english name in path to docs and may crash.
Not sure if it was fixed

Fairly sure it's all english, but I did buy it from 3dsky, so high possibility it's not!

Thanks will check it out

Further info:

I made a completely new scene in max 2020. (Previously working in 2018, where the last scene was initially made).

I copied the rug into the fresh scene and viola, no crash (yet).

This might be the way to go?

Hey aaouviz I took a look into your scene, in the initial scene where you are experiencing the crash, are you rendering with DR (because it's on)? Also did you manually put to save the UHD cache into a dropbox path on one of your drives?

Does disabling the Distributed Rendering solve the crash for you? Can you please try and report your results?

I was using DR, yes, but when testing the fur crashing my DR wasn't functioning, although switched on. Also, the crashes were happening during IR tests too, so no DR here, right?

Not sure what you mean "manually put to save", but I was (at some point using UHD saved in a dropbox folder).

Will test this out for you now.

Bah! Now I can't replicate the crash at all either. Any any circumstances. Weird.

Seems to be all OK (for now). So thanks for the help....

Glad it works for you now, I am afraid I am able to reproduce it many times but never with IR, only production, anyway thank you for the input on this it's being reported.

It will be investigated further just to be sure.
