can you share the scene? You can also share it privately by starting a ticket with us: https://support.chaos.com/hc/en-us/requests/new

Note: you can also share images showcasing the problem (renders, viewport screenshots, material setup) here so that we can understand better what is going on

[Max] Bug Reporting / Re: Export Vantage "Failed to export the scene" occurs on many scenes

Interesting. For me "Render in Vantage" button is working fine for your scene. Is it possible for you to attach a screen recording to see If I am not missing anything?

Hey,

I tested the scene attached but it seems to be working fine.

Can you let me know the steps you took before this error appeared? Which button did you use for exporting? "Export Scene"|"Export+Render"|"Render in Vantage"

Hi, which DoubleSided material are you referring here? 3ds Max native? V-Ray? or something else?

[Max] Bug Reporting / Re: Multiple Maps in Scene Env loads all of the textures at rendertime when disabled

« on: 2024-08-21, 13:46:35 »

Hi,

I discussed this further with our devs, and it seems like this is expected as once the bitmap is loaded for the given scene it remains in memory until it is removed from the scene. Since the bitmap is still part of the multimap (part of the scene), it remains in the memory. This is needed by 3ds Max for various operations such when you open the material editor. Keeping it in memory prevents the need to reload it multiple times, which could otherwise lead to performance issues.

As a workaround for now, we recommend removing any unused HDRIs from the scene entirely if you don't want it to load in RAM and you can also use out of core corona feature if you are running out of ram.

We have also logged this in our system to see if we can further improve this in future.

Hi,

Thanks for further info but I still can not repro this on my end. Changing location should not effect this.

It would be best if you and your friend can start a ticket with us so we can investigate it further.

[Max] Bug Reporting / Re: Multiple Maps in Scene Env loads all of the textures at rendertime when disabled

« on: 2024-08-21, 06:10:28 »

I render different frames with different lighting setups and keep all of the HDRI's in the Multiple maps list. I only use one HDRI at a time as a Single Map, the Multiple maps tab is always disabled.

For some reason, Corona loads every HDRI in the Multiple maps list when it's disabled. I'm not using LightMix or any on the LightSelect render elements. These textures are not assinged to any other object in the scene. They only live in the Multiple Maps list which is, again, disabled.

The problem is, I'm already working with very heavy scenes and loading multiple unused HDRI maps really messes up the memory usage. I get the memory warning and it's always the HDRI maps hogging the memory.

I think this was an oversight, I can't think of a reason for Corona to load unused textures. Any fixes for this is very much appreciated.

Hi, I am currently investigating and discussing this issue with our devs. Will update you.

[Max] Bug Reporting / Re: No License after different user logs in

« on: 2024-08-21, 05:36:53 »

Ok, sure thing.

However, I don't really think this is an issue with the license, per se.

It's clearly a bug. And it's still happening... should we discuss here or do you want me to still submit a ticket?

Even if there is a bug in licensing, it is best to report this to our licensing team via ticket. If it is super super urgent then feel free to share here and we will try our best to help you.

[Max] Bug Reporting / Re: CHAOS COSMOS - DRAG AND DROP FUNCTION

« on: 2024-08-21, 05:34:04 »

Hi Avi, good day. Thank you for your response!

I can't tell you exactly when does it stop - because I'm not observing it and recording the time.
Let's just say an hour later.

Another consideration - I'm leaving my PC in the office open, and 3Ds Max is also open, the next day, Chaos Cosmos' Drag and Drop function is not working anymore.

Can you let me know which version of Corona and Cosmos you are using?

[Max] I need help! / Re: The file closes while Rendering

« on: 2024-08-20, 07:56:33 »

Hello, I am working on a file, there was no problem. I bought a chair model from the site and merged it. Then, every time I press the render button, 3ds Max closes and when I try again, I get the same error. There is no problem when rendering in another file. How can I fix the problem in this file, please help?

Can you start a ticket and send your scene for a quick investigation?

« on: 2024-08-15, 12:40:28 »

Since this scene came from Max 2020 and Corona 11, I tried creating a new material with the same characteristics, and it worked.

Good to know , it is working now.

[Max] I need help! / Re: Help with faking a lighting effect

« on: 2024-08-15, 12:39:29 »

As the sun starts to disappear I get this incredible lighting effect happening in my living room.

I'm wondering how to fake this because the recreating the reality would be huge overkill imo.

The reality (see second pic) - as the sun sets it reflects off this nasty cheap wavy perspex type material.  The perspex is really dirty and really warped/bendy.  Behind the perspex is a stained glass window.  The light then bounces into my living room, through my bay window, which has double glazed sash windows, and finally through the shutters and onto the living room wall.  The result is the gorgeous effect you see here.

How would you recreate the effect without modeling/shading the reality of the environment that's creating it?

You can achieve this by using gobo lighting technique.

Use can use Max native target light with a texture. You can use Corona light also but for this fake lighting effect, 3ds Max native lighting works better.

If a HDRI/Texture is being used during rendering, they will be loaded in RAM. Maybe your HDRI are being used in the lightmix setup during rendering.

You can also use out of core rendering for texture. You can read more about it here: https://support.chaos.com/hc/en-us/articles/9477508142993-Out-of-core-Rendering-for-textures-3ds-Max
