[Max] Resolved Bugs / Re: Corona 12 doesn't render scenes created with version 11

« on: 2024-08-23, 15:59:13 »

This case was solved through support ticket #266705. The solution was to remove legacy Mental Ray assets using the 3ds Max Scene Converter. (not the Corona Converter!)

The garden behind ribbed glass looks really awesome! It's a very popular material now, but I haven't seen it used that way yet.

[Max] Bug Reporting / Re: Phoenix Particle points wont render Caustics, Bubbles mode Do

« on: 2024-08-23, 14:21:02 »

Looks like a bug, successfully reproduced and logged as (Report ID=CMAX-1241).
It seems that selecting the particle shader object and disabling "cast shadows" in its object properties fixed it (right click > object properties > cast shadows).

[Max] Bug Reporting / Re: CXR saving problem with Corona 12

« on: 2024-08-23, 13:59:14 »

Hi maru, unfortunately it isn't solved.

Here you can see a screenshot (and you can image what it looks like with more than 20 renders)

which is created by,
- started batch render
- canceled it, and started saving immediately.

if we let it run, and not cancel it, it saves as it should(correct sizes).

OR

- Anything we send to deadline concludes to the same result.

For a bigger project, we had to switch to corona 11 again. Hopefully this will be fixed soon, because in the office environment, it is not usable right now.

I did not fully understand this message, so here are my questions:

1. Are you using 3ds Max batch rendering or Deadline?

2. What exactly do you mean by this:
"- started batch render
- canceled it, and started saving immediately."
You canceled batch rendering and then manually saved the output?

3. What exactly do you mean by this part:
"Anything we send to deadline concludes to the same result."
Does "same result" here mean the bad result (1 large beauty and multiple large elements) or the good result (1 large beauty and multiple small elements)?

Thanks in advance!

[Max] Feature Requests / Re: Ambient Occlusion with shadows turned off and object invisible.

Disabling the "visible to camera" option works, but the object still casts shadows. If it doesn't cast shadows, then it does not generate AO either. I am afraid this is impossible to do with Corona.

[Max] Bug Reporting / Re: Chaos Cosmos in 3ds 2025 has texture problem.

« on: 2024-08-23, 09:11:14 »

If you could tell me what Im doing wrong here, I would be very grateful.

I am sorry, but I do not understand what is happening in your video. It looks like you are clicking various icons (Cosmos, Render Setup), but nothing is happening, the windows are not displaying. Is this the problem you wanted to show?

If yes, then please submit a new support ticket at https://support.chaos.com/hc/en-us/requests/new
This is because cases where Cosmos is not working at all are handled by the dedicated Cosmos support team.

[Max] I need help! / Re: material editor SLOW - i think its a CORONA issue?

« on: 2024-08-22, 09:08:31 »

I have personally never ever experienced a slowdown close to this. I am attaching a recording from a Ryzen 3900X, 3ds Max 2025, Corona 12 HF1.
Please provide basic details such as your CPU model, Windows version, 3ds Max version, Corona version.
Also, is this happening in any scene, or only in some specific one(s)? For example, if you take an empty scene and open the material editor, is it the same? Or does it only happen when a heavy scene is loaded?
Is this happening right after you start 3ds Max, or you need to work with the scene for some time and only then it starts happening?

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

« on: 2024-08-21, 18:13:56 »

As Avi advised, please submit a support ticket. Any licensing issues are handled by a dedicated team and there are some very solid reasons why we do not provide licensing support over the forum. For starters: we don't know what license type you own and we may need to ask you for your personal information to find out.

@Tanakov - I was not able to reproduce what you are reporting, but the result from your "screenshot 2" is what the material looks like when imported with the V-Ray version of Cosmos. Make sure that you are launching the correct version of Cosmos (from the Corona toolbar) and that you have Corona set as your active renderer.

[Max] General Discussion / Re: Corona 10/11 - Corona Render Assets loading very slow

« on: 2024-08-21, 11:01:30 »

During parsing, assets are loaded into RAM, so it does depend on network/storage speed, yes. If you disable the "keep in RAM" option for a proxy, it will be loaded just once and kept in RAM.

[Max] General Discussion / Re: Corona 10/11 - Corona Render Assets loading very slow

« on: 2024-08-20, 16:14:13 »

Is there a log/report or something stored after file open, where I can see loading time and name of the assets causing the issue?

Unfortunately, no. If you send us a scene, our developers will be able to find out which assets are taking most of the opening time. You need special debugging files for this.

Sorry, but it's a bit too hard for me to imagine what exactly you are doing. Could you please add screenshots, renders?
