[Max] General Discussion / Re: System low on RAM:

« Last post by Avi on 2025-09-11, 20:01:11 »

Hi,

The paging file is managed by Windows automatically, not by Corona. We recommend keeping it set to "System Managed".


If you’re running out of RAM, the best first step is to optimize the scene. If you feel the same scene in Corona 10 uses much less RAM but in Corona 13 HF1 the RAM usage is drastically higher, please open a support ticket and share a short screen recording so we can review the comparison clearly:

In the meantime, this article may also help you troubleshoot further:

Gallery / 3D Visualization of Sustainable Charging Solutions for Electric Vehicles

« Last post by Render Vision on 2025-09-11, 19:44:25 »

https://forum.corona-renderer.com/index.php?board=3.0


Customer: Mer Solutions GmbH
Location: Munich, Germany
Visualization: Render Vision

In this 3D render, we showcased how charging stations function in real-life environments — from private homes and underground garages to logistics hubs and public areas. 🏡
Every scene was created with photo-realistic precision, capturing the interaction between architecture, vehicles, and charging stations — both above and below ground. Our goal was to reflect the client’s mission: enabling smart, green energy use in everyday environments. 🌍🔋
We paid close attention to detail — materials, lighting, and spatial context — to make the technology feel like a natural extension of its surroundings. More than just showing the product, we focused on how it works, where it belongs, and why it matters.
Our 3D renders help turn ideas into reality — showing not only how a solution looks, but how it fits into the future. 💡

Hi,

We may have a clue what is causing it, may be related to instruction set for specific CPU types.
If there is an implemented fix, it will most probably be in the next preview (daily build), so stay tuned to check it.

[Max] General Discussion / System low on RAM:

« Last post by Darawork on 2025-09-11, 17:53:49 »

Hi,

I've been getting this error for a few years now, as I only have 64GB of RAM on my workstation. This wasn't ever 'that' much of a problem as it would usually render out fine, just a bit slower.
That was using Corona Render 10.

Now I'm using Corona Render 13 (Hotfix 1), and when the RAM runs out, the rendering seems to go very, very slow.
I also noticed that my HDD D:Drive is being used for the Page File (This might have been done by IT here for some unknown reason) and it goes to 100% usage (Read speed 1.3mb/s Write speed around 2.0mb/s). Ideally I would prefer the Page File to be set for the System nVmn SSD, as this might be a bit quicker to read/write.

My question: Has something changed the way the system paging is working behind the scenes from Corona 10 to Corona 13?

I have increased the Out-Of-Core limit from 100GB to 250GB with the default 10% Drive remaining parameter unchanged. This doesn't seem to make much if any of a difference.

Hopefully I'll be getting a newer Workstation soon, with a decent amount of RAM, but for now I'm stuck with 64GB.

86.5 GB of virtualized* RAM used by Corona + 3ds Max
102.9 GB of virtualized* RAM used by all running applications
63.7 GB of physical RAM installed on system
171.7 GB of virtualized* RAM provided by OS

* virtualized RAM means physical RAM + swap file on HDD/SSD

Corona RAM usage breakdown:
747.8 MB used by render elements
31.7 GB used by geometry

Best Regards :)

[Max] General Discussion / Re: check/clean-up scenes that takes ages to load?

« Last post by mase on 2025-09-11, 16:15:32 »

Not sure how much each of the steps contributes to the total reduction of opening time but some routine we have in an office is this:
1. Prune scene, inspect with SiNi and delete any missing plugins / animation layers etc.
2. Make sure you don't have many external paths in your 3ds max settings. There are different views on this but generally the more paths you have on Customize > Configure Project paths, the longer each file will load as 3ds max will check each folder before opening the file to see if it can find missing bitmaps there. This is even more annoying when opening old files, as paths are usually lost so max tries to scan each folder, and there might not even be anything project related there. Sometimes this can even crash the file so better practise is to have few paths in there and later relink missing bitmaps manually, or with some scripts.
3. As others have mentioned, xrefs play a huge role too.  There used to be a script that disables xrefs when opening a file (can't find it right now), but I found another script that could also be useful - it disable all "missing this and that" pop-ups when opening the file. This is extremely frustrating when opening large files again, as you might forget about opening a large file for a while and when you press on it you suddenly realise it was waiting for you to press SKIP. You can find it here - https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/How-to-suppress-Waning-dialogs-when-opening-a-scene-in-3ds-Max.html
4. And lastly of course, if you work over network it's highly recommended to copy file locally, do what you got to do and then copy it back to the server. This can cause massive lag depending on your network setup, file paths etc. I sometimes forget that I have Everything running in the background, scanning all of our server and it just freezes the server completely if it needs to load anything.
5. Final advice, after opening an old scene I recommend merging everything into a new file, doing some quick cleaning and re-saving it. Sometimes, depending on how old some projects are, because of many new Corona / 3ds Max versions old things tend to break even though nothing got changed. So this merging procedure allows you to double-check if everything is alright (merging in parts of course) and generally is a good time to setup your scene nice and clean.

Hope that helps.

Nah, no one is chocking no one - it's still a free choice. Just 'the gap keeps getting wider'.
And know, this C4D 'streamlining' has been in works for over a decade now (from abandonment of modules, via transitory packages into "Maxon One" 'singularity'). Also, Maxon would probably be dismantled, if there weren't for the "Nemetschek group". Landscape changed, and every 'dinosaur' still consumes a whole lot, but must also evolve, ever since the 'global "http" impact'... and lately with all the little ai, ai, ai... :)

PS
Corona should really consider making 'standalone'. Tho, 'papa' is long gone now... rip.

Hi frv,

I TOTALLY AGREE!!! I am a freelance 3D designer & visualiser, work is so sperodic at the moment and being HAMMERED with licences left right and center. I really wish Maxon could do a stripped down version without friggin RS and do it for less, shame on them, they are choking the creative industry.

With CIE every time I try to do a 'save all' to jpeg I get an instant crash.

Known problem? I can provide crash report if this is new?

Edit: CIE seems to be all types of messed up? Is this all known? See example below of how a lightmix pass looks in CIE vs how it is saved as jpg. What's going on?

Hi,

These are known and already reported. I wonder if you had any issue specifically with the UI/UX.

Hello,

Any news about this?

Cheers!
