Hi,
 
Thanks for your patience. Our developers have prepared a fixed build of Corona 13 Hotfix 1 that should run properly on your affected machine: https://drive.google.com/file/d/1Q150zS4n-Yn9OjlfYYAH-qQFtknzfW-G/view
 
Please note: this is provided only to test whether the installation works correctly. It is not an official stable build. Once you try it out, let us know the results so we can confirm and finalize this.

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:

[Max] Bug Reporting / Re: After a period of user inactivity the next render is slow and use 100% of HDD

This sounds like a issue with windows "https://learn.microsoft.com/en-us/windows/win32/memory/working-set"

Try disabling windows defender, setting power option mode to high performance and you can also go through this article and try the solution listed: https://www.wisecleaner.com/think-tank/507-3-Solutions-for-Windows-10-Standby-Memory-Issues.html

You can also try disabling Sysmain (Superfetch) by opening services (services.msc), find "Sysmain" and disable it. this prevents Windows from aggressively managing memory (If you dont see any improvement, re enable it).

Also after a bit of research I found this issue and it sounds related: https://www.installaware.com/forums/viewtopic.php?t=10434

Try deleting all temp files from %temp% and %userprofile%\AppData\Local\Temp

Can you try disabling any antivirus and install the latest VC++ redistributables from here: https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170 and see if it fixes the issue.

Hi, Just an update from our devs that it can be extracted using openexr library. So it is the right way. I hope this helps.

[Max] I need help! / Re: How to Accurately Identify the Last Rendering Mode

« on: 2025-09-03, 20:42:31 »

I’ve made a simple MaxScript(USING AI) that can tell you whether your last render was done in Production or Interactive Rendering.

How it works:
- Corona’s `CoronaRenderer.CoronaFp.getRenderType()` only works while a render is running 
  (returns 0 = Production, 3 = Interactive).
- To get around this, the script uses a `#postRenderFrame` callback which captures the mode just before the render ends.
- It then saves the result in a persistent variable and updates the render stamp with either [PROD] or [IR].

This way, after rendering finishes, you can still see which mode was used in the VFB stamp.

Script attached below.

I am using Corona 13 HF 1 and I tried running 3ds Max as ADMIN but I am unable to reproduce this same thing on my end. Can you help me with the steps so I can try to find out more about it? Also which version of 3ds Max you are using?
