Not sure what you mean by stopped answering you - was there a ticket number, where you are not receiving any replies? Thanks!

[Max] Resolved Bugs / Re: Low cpu usage (40%)
« on: Today at 15:33:43 »
What about with Corona 11, since this is a very very old thread and we've had two versions since then (and about to have a third before too long :) ).

The total noise amount is averaged, but adaptive sampling means Corona puts more processing power into areas that are noisy.

If it crashes for us opening it, definitely not a waste of time, as we'll be looking to fix that crash too as a bonus extra. TBH sending in a scene always helps, so is never time wasted. And we do appreciate you taking the time to do that!

Hi! All the links to the photos in the thread are broken now, looks like something changed with wherever they were hosted - in case you want to correct for that to bring them back :)

[Max] I need help! / Re: How to use full Computer POWER while rendering
« on: 2024-05-16, 21:19:08 »
You got lucky that the scene last week wasn't also incredibly slow. The low RAM warning is one that has to be taken seriously - at worst, speed can drop to about 10% of what it should be (as the CPU has to wait for data from the hard drive, which is much slower than waiting for data from the RAM), or in other cases can just outright crash.
32GB of RAM is considered a minimum these days, with 64GB being more of a sweet spot (though there are users who have even more than that, for sure), so a 16GB machine is going to struggle when the scene hits any sort of complexity. There should be a link in that message that you can click on which will give advice on optimizing the scene, though the preferred solution if budget allows is simply to add more RAM :)

[Max] General Discussion / Re: Single vs DR render passes
« on: 2024-05-16, 17:15:17 »
Coupla starter questions. How often are the machines set to communicate with each other? And are they all the same speed?
There is generally some overshoot possible, e.g. master machine is slower than the others (maybe because it's in use for other things at the same time, as well as hardware), so when it goes "Oh hey everybody, 3% noise, we got it!" the other machines go "Great! Ok we are stopping, and here are the last 20 passes I did since you last asked me", which across 7 machines would be an extra 140 passes. This can happen even if the controlling machine is not slower, again depends on how often they are set to checkin with each other.
What's the breakdown on how many passes came from which machines, btw?

[C4D] Feature Requests / Re: Support for AMD GPU Denoiser ?
« on: 2024-05-16, 12:50:25 »
No developments on this front at the moment. We plan to revisit denoising and do a general overhaul (but not for 12) of everything, including UI, so we'd look into the generalization of the Intel denoiser then.

DCC is Digital Content Creation or in this case Creator - ie, 3ds Max or C4D with associated version number :)

[Max] Daily Builds / Re: CoronaPattern playground!
« on: 2024-05-15, 16:04:37 »
The changes in the daily are pretty much it for the 12 release, the primary one being the ability to access both the pattern's and the base geometry's UV maps. Direction indicator should be handy too.
The caps may be useful, but these only work on holes created by the Crop Box, so if for example your source mesh already has a hole at the edge of the crop box, this will not be capped by this functionality (you have to cap the source geometry), nor will holes created by having partial tiling such as 1.2 rather than 1, just to help guide anyone doing testing on there.
The plans and answers to things on the list you posted will have to wait until 12 is out and we look ahead to future plans, as we're entering into the final run up to release in just over a month, making it all hands on deck focused on the 12 stuff only. We do have all these ideas tucked away to look over when we get there, though!

[Max] General Discussion / Re: Does a higher resolution image require more passes?
« on: 2024-05-15, 15:56:50 »
Actually, higher resolutions usually need less passes to visually "look as good", though I don't know how that translates into noise level. But of course it still takes longer to get there, due to the extra processing needed for all the extra pixels :)

[C4D] Feature Requests / Re: .CXR Extension made available as a render queue option
« on: 2024-05-15, 13:34:02 »
Nothing to announce as yet - it will involve re-writing the export routines for ourselves rather than relying on the DCC routines, if I remember right, which is not a small undertaking. Something we definitely want to do though, just not a timeframe on it yet :)

User-Facing Improvements
If you are familiar with the daily builds and know how to use them, download the newest one here:
chaos-corona-12-3dsmax-daily-2024-05-10.exe
User-Facing Improvements
- Added accurate sampling mode for environment maps that is slower but delivers more accurate results (especially for large environment maps)
- Added option to distinguish media based on their material (e.g. two intersecting objects with the same material will be now considered as a single volume)
- Added option to delay Bloom&Glare computation after rendering
- Improved the conversion from VRayMaterial to Corona Physical material (especially metals and colored reflections), this change influence also imports from Chaos Cosmos
- Extended range of solar elevations supported by the PRG sky model, now is possible render all solar elevations down to -12 degrees
- Added rollout in CoronaCamera to define Environment Overrides. Each override can be defined with 3 options: Inherit (default), Enable and Disable
- Added warning about Corona not fully supporting OCIO color managment workflow
- Added the possibility to define visibility of Corona Pattern using texmap
- Corona VFB now displays the rendered image with correct display/view transform when OCIO color management is used
- Added back support for motion blur in Corona Standalone
- Metalness setting in the converter is now respected when converting V-Ray and Autodesk Physical materials
- Superfluous sky darkening by the clouds for low solar elevations removed
- Fixed issue with 3dsMax crashing, when CoronaCamera is created from Corona Toolbar
