[Max] General Discussion / Re: 3ds Max stuck at startup when copying ChaosGroup ConversionScripts

« on: 2023-05-04, 04:19:26 »

Can you give details about the other Chaos products installed on the user's system who has this script "ChaosGroup_To_*.ms". Also, please let us know the versions of these products.

As far as I have checked, Corona doesn't have any such script. It maybe coming from other Chaos products so if you can let me know, I can narrow down the issue.

Now that you have re-installed everything in your system, do you have this script?

The solution mentioned above by others can work and you can also look into pulze scene manager for doing similar things.

Hi,

if you don't use a decal and just directly use this texture in your base paint layer, does the reflect pass look any different?

Hi,

since the full name and content of that script are unclear to me, I don't know what could have caused the issue.

But since you are reinstalling everything again, I hope it should fix the issue. If the issue persists, then we can look further into it.

Hi,

What version of Corona you are currently using? I would recommend using the latest version which is Corona 9 HF 1 (at present) and also if you can please try using the Corona 10 DB version as there were some nice caustic improvements. You can download Corona 10 DB from here: https://forum.corona-renderer.com/index.php?topic=38385.0

Also, I would suggest you go through our informative and detailed helpdesk articles as they can give you enough insight on how to effectively work with Caustics in Corona.

Note: The daily builds are the newest, experimental versions of Corona Renderer intended mainly for testing purposes and to showcase the recently added features. They contain the latest bug fixes but are not guaranteed to be stable, and in some cases can even damage scene files.

Hi,

Can you let me know which version of Corona you are using with your 3ds Max 2023 and can you navigate to this folder "C:\Program Files\Autodesk\3ds Max 2023\SceneConverter\ConversionScripts" and tell me the full name of the script that is causing the issue?

I am currently using 3ds Max 2023 with Corona 9 HF 1 and in this location "C:\Program Files\Autodesk\3ds Max 2023\SceneConverter\ConversionScripts" , I don't have any such script named as "ChaosGroup_To_*.ms"

[Max] I need help! / Re: Losing Lightmix Setup When Loading 3ds Max Render Presets

« on: 2023-05-01, 12:15:01 »

Hi,

To make sure that your Lightmix setup remains intact when you load a saved render preset, you need to select the "Render Elements" option as well with the rest of the settings you want to import. You mention that you only selected the "Envrionment" option so, so you are not loading render elements so, light mix won't work.

[Max] General Discussion / Re: Stop vs cancel when you want to resume from cxr file

« on: 2023-04-26, 13:11:23 »

Hi,

I understand your issue and confusion. The error should only appear when you use the "Cancel" button instead of the "Stop" button, because when you use the "Stop" button, denoising is calculated and stored with some hidden internal render elements in the CXR file. However, there is no denoising part happening when you use the "Cancel" button, hence the error.

Upon further investigation, we found that the error is still showing even if you are using the "Stop" button. We have logged this as a bug report in our system and will be further reviewed by our devs.

In the future, if you want to resume rendering for your files, consider using the "Stop" button, as this will save the necessary information for denoising to be used later.

Hi,

our devs have suggested the following code. Please try this and let me know if it solves your issue.

Code: [Select]

corona_sun = getNodeByName "Corona Sun001"
corona_sun.position = [5,5,5]

Replace the "Corona Sun001" string by name of the Corona Sun in your scene

« on: 2023-04-17, 16:29:41 »

Hi,

First of all, I would suggest you always use the latest version of Corona as if there was any such bug in the past, it is possible that it may already have been fixed in the latest version which is Corona 9 HF 1. You can download the latest version from here: https://corona-renderer.com/download

It's difficult to pinpoint the cause of the issue without checking the scene. Therefore, it would be best if you could contact us through our support ticket system and send us your scene for a quick investigation. This will allow us to better understand the problem.

Hi,

is this script any different from the 3ds Max native Daylight system which you can use with Corona sun, that does the same thing?

I know it shouldn't, but who knows, unless we figure out how the Images were saved. ;) It's just one of many factors I mentioned that could have contributed to the user's issue. I believe this thread covers all potential solutions to the problem the user is facing.

3. I see that you are saving in the .tif format. When saving, see if you are not using any compression for it or you can also use .EXR or .HDR. These formats preserve more color information and can help reduce differences in color.

This is misleading answer. File Formats are unrelated to Color Profiles (outside of supporting or not supporting them) and do not in any way reduce any perceived color difference, in fact they are capable of opposite since HDR file formats require wide-gamut colors to cover properly the extended dynamic range.

Not that it matters, 3dsMax/Corona outside of 2024 version do not embed any color profile information at all anyway. Jpegs or EXRs, 3dsMax/Corona outside of 2024 provide zero color management. File Format should be chosen depending on intended post-production workflow, SDR (Jpeg/Tiff/PNG/etc..) or HDR (.Exr, .Hdr).

Edit: I have yet to test 2024 Max, to see if Corona respects the new color management (and if it respects the current Windows .icc profile). I hope it does.

Sorry if this was not clear but I was referring to these file formats specifying how image data is stored i.e. some formats(Exr and Hdr) can store more color and luminance info than others. I hope you were not using some kind of compression at the time of saving the .tif file format. The color profiles however is a separate thing from file formats.

Hi,

I have a few questions:

1. What version of Corona and 3ds Max you are using?
2. What does your material setup look like? (Post some screenshots along with a short description)

[Max] I need help! / Re: Image colors changing after saving

« on: 2023-04-17, 09:22:29 »

Hi,

I understand that you are having some problems with differences in colors after saving your rendered Image from the VFB in Corona. This could be due to a few factors. I will suggest some possible solutions:

1. Make sure that your color management settings are consistent across all software you're using. In 3ds Max, you can access these settings by going to Customize > Preferences > Gamma and LUT tab. Ensure that the "Enable Gamma/LUT Correction" checkbox is selected and that the Input and Output Gamma values are consistent (typically 2.2 for sRGB).

2. Different software may interpret color information differently, so ensure that you're using color-managed software for image viewing and editing. For example, use Adobe Photoshop or a similar application with color management capabilities.
"Color management is quite simple, and relies on two things:

– The image must have an embedded profile (known as the document profile),
    typically sRGB or Adobe RGB.

– The monitor profile must be correct and sound.

 When you open an image in a color-managed application, the colors are converted from the document profile to the monitor profile, which ensures that the correct colors are displayed.

Applications without color management (like Windows Photos) do not do this conversion"

3. I see that you are saving in the .tif format. When saving, see if you are not using any compression for it or you can also use .EXR or .HDR. These formats preserve more color information and can help reduce differences in color.

4. It's possible that your monitor's color profile is affecting the appearance of your images. Check your monitor's calibration settings and ensure that it's set to a standard profile, such as sRGB or Adobe RGB.
