any news on this issue... I am having a similar issue here as well

Hi mcnamex, are you using forest pack or back-burner for batch rendering?

Yeah FP,RC,Backburner. But rendering locally behaving the same as well.

We are currently investigating this issue, if you could raise a ticket or  provide a scene for us it would be helpful.

Hi,

So thanks to Gabor for sending over a scene!

We are now able to reproduce the problem of the geometry processing times increasing with each frame in the animation.

I have fowarded this on to our dev team for futher investigation. I will let you know when I have some more information.

Cheers,

Rowan

Hi guys,

I'm experiencing the same issue, using only cproxies and cscatter and some plugins like bercon maps, floor generator. All scattered instances are cproxies with enabled.
Look the attachements.
The biggest difference is not visible in these numbers - it's tansforming vertices - from several seconds in the begining rised to cca 7:30 minutes on 20th frame.
I will be able to send the scene on this friday probably. The animation is not crucial for me, I'm doing mostly stills, this was just a preview for possible output.

Adding some info:

win10
max 2019
corona5
amd threadripper 1950
64gb DDR4
nvidia rtx 2070

I have another question. Is it beneficial as to performance to enable temporal consistency for this type of scattering? According to thumbnail I would say yes, but it apparently didn't afect this problem of scene parsing time getting longer.

Thanks ;)

It seems there is something bad with max itself. Max became really tough, even when autosave file is saved within few seconds (160MB), max is unusable for several minutes (cca 5) with only one proc core fully loaded (no disk usage or rising memory consumption). I guess it also has something to do with many individual cscatter objects, in this way my scene is pretty heavy (26 csatters).

Hey guys,
any news here? My support ticket was closed, but unfortunately there was no solution for the problem. Maybe this could be corrected in the upcoming version of Corona?
Did any of you find a possible workaround?

Hi,

I have a short update for this. We did some investigation and managed to find the root cause of this.

We have managed to fix the increasing times in scene parsing, this will be in the next v7 Daily Build.
BUT the increasing time in Geometry processing is still there. This is due to the fact that there is a bug in an external library we use which causes this. We are working with the devs of this library to fix this.

Thanks for your patience.

Rowan

Any news on this issue? I have the same problem but parsing freezes Max and I have to force close every time. Unusable. Just downloaded the daily to see if it helps.

Hi,

Please submit a new thread explaining your issue. This one is pretty old and maybe have a different route cause.

Can you provide also the following information;
Corona version
3ds Max version
What exactly you were doing at the time
If possible your 3ds max scene
If possible a minidump from the freeze.

Instructions on how to send the files to us are in my signiture.

Cheers,

Rowan

Hi,
I have the same problem out lined here. I have found a couple of threads about this frame time increasing problem but they offer no solutions. Has anyone resolved this problem of the parsing time increasing every frame?

Hello,

I am rendering a couple of animation sequences, the loading times for parsing scene is quite long, takes aproximately 2 - 3 minutes, with usage of half of my computers RAM, and oscilating between 50-60% of usage of processing power.

I read that parsing scenes takes time because of low RAM, however this is not the case here. Is there anything that I can do to remove parsing times? 2-3 minutes extra parsing times for each of the hundreds of frames is quite unfortunate.

EDIT: More information about my scene (as per information here: https://coronarenderer.freshdesk.com/support/solutions/articles/5000675854-system-is-running-low-on-ram-you-may-experience-excessive-parsing-times-and-or-crashes-you-will-pro)
[altough I know all of the points below are mainly to lower RAM usage, which is not necessary in my scene)

1) I have only 4 passes including Beauty pass; no atmospherics or AO pass - denoising 4 passes only.
2) No displacement
3) No super high resolution textures
4) Lots of instances and proxies
5) Resolution in HD only (not full HD)
6) Ram usage 50 percent, so I have enough RAM (47GB RAM usage, ~82GB RAM installed total)

Any info would be appreciated.

Hi,

I am from the corona team & I would need some additional info to investigate your scene.

1. Can you let me know the 3dsmax & corona version you are using?
2. Can you send me your scene for a close inspection. You can use our private uploaded to send us the file. Link : https://corona-renderer.com/upload

Once you are done uploading, do let me know the file name.

3. Can you let me know the step by step process to reproduce the same results?

Looking forward to hearing back from you soon.

Regards,
Avi

Any progress here? I am using the latest Corona with the latest 3ds max, still this same, very old problem exist. The more complex the scene is, rendertimes increasing more and more from frame to frame. Very annoying. Parsing scene and preparing geometry times are constantly increasing when rendering animations.
