Why exactly doesn't self-illumination work for you?

Just for a test, could you please try disabling SMT (simultaneous multithreading) in BIOS and see if there is any improvement in the overall system performance?

I think this should be possible with render managers such as Deadline or Pulze. You would need to check with their support to confirm.

[Max] General Discussion / Re: Path Tracing always as Secondary GI Solver

« on: Yesterday at 15:30:22 »

For interior animation - PT+UHD (with "animation (flicker-free)" preset enabled in UHD settings).
You can use PT+PT, but the rendering will be much slower with little visual difference.

For exterior animation - PT+PT. If there is something with lots of GI visible (light bouncing around) it could also make sense to use PT+UHD.
The reason is that if the rendered image mainly shows direct lighting (think of a grass lawn + some trees + cars) then you don't have to compute the UHD Cache as it would not speed up rendering. UHD speeds up anything where there are some clearly visible light bounces (think of a room where the sunlight hits the floor and lights up the interior).

You can use PT+4K (4K with the "animation" preset enabled as well), and the usual disclaimer applies.

So for interiors we should use PT/4K?

My advice would be: use the defaults (PT+UHD). If you want, you can also try PT+4K, but 4K comes with an "experimental" disclaimer.

[Max] I need help! / Re: Color Difference between Corona VFB and render output

« on: 2025-09-15, 17:49:17 »

We had some similar cases in the past. This comes from the fact that 3ds Max+Corona is not "color profile-aware". The most straightforward solution is switching your monitor to sRGB in its OSD settings.

Hi, how exactly do you copypaste the asset from one Max to another?

The simpler reproduction steps are:
- save anything in .cxr format in any version of Corona
- open with v14 CIE
- save with v14 CIE

:)

This is now reported as (Report ID=CMAX-1864).
Thank you!

[Max] Bug Reporting / Re: Memory leak

« on: 2025-08-28, 17:54:30 »

I think the crazy RAM usage here is the result of a few things in the scene, but they all seem to be related to the Legacy Mtl. For example, if you lower the Legacy Mtl's Fresnel IOR from 100 to the default 1.52, then it renders fine. Also, if you isolate either of the objects, it renders fine (even with the "wrong" materials and render settings).

Since the Physical Mtl is here to replace the Legacy Mtl and it already contains various fixes, I don't see a need to log this for the devs.

« on: 2025-08-28, 09:49:29 »

I tried with various CPUs, with V13 HF1 and the V14 daily and I am getting the expected results. Can you try with a lower number of threads used? For example 50% only.

One thing to note here is that "16 out of 32 threads" here doesn't mean that you will see only 16 logical CPUs working at 100% in the Windows Task Manager and the other 16 sitting idle. The work will be distributed between them in a more "random" way. But it should be 50% overall.

Sorry for a silly question, just trying to rule out some possibilities - are you adjusting the correct number of threads? (there is one for production and one for IPR)

In my simple test the issue seems to be the same in Corona and V-Ray. If anyone has a V-Ray scene where this is clearly not happening, please contact us at https://support.chaos.com/hc/en-us/requests/new
