[Max] I need help! / Ryzen 9950X performance issues (freezes)
« on: 2025-02-19, 14:48:07 »
If you are getting the following issues:
- While interactive or production rendering with Corona, the whole system freezes, you are getting mouse cursor stuttering, or there is some other kind of "slowdown"
- Performance randomly goes back to normal
- This happens even in very simple "teapot" scenes
- You observed that previous Corona versions worked smoothly and Corona 12 Update 1 Hotfix 1 is suffering from this problem

The solution is to fully update your Windows. The required Windows Update is 26100.3321 (KB5052093) or newer.
Please also make sure you are using the newest version of Corona from https://www.chaos.com/corona/download

If updating Windows doesn't help, please go to your BIOS and disable an option called EXPO (sometimes it is also called XMP or DOCP - it's responsible for memory overclocking). The option should say "disabled" or "off".

Big thanks to forum user Quest, who actively investigated the issue and shared updates with us!

[Max] Daily Builds / Faster caustics + volumetric caustics playground!
« on: 2024-10-11, 18:06:57 »
The newest daily build of Corona features new improved caustics. They can be used inside volumes, be it global volume, Corona Volume Grids, Phoenix simulations, smoke, fog, murky water - you name it! They also generally render faster both on surfaces and in volumes. You can also control the intensity of surface caustics and volume caustics independently (in Render Setup > Performance).

Please note that this feature is still a work in progress, so treat the following examples as pre-production samples. We are working on further improvements!


Quick how to:
- Set up your objects with volumetric materials
- Cast some caustics onto them (directly with a Corona light, through a refractive object, reflected off a metallic surface,...)
- Make sure you have the Caustics Solver enabled in Render Setup > Performance
- Render!

[C4D] Daily Builds / Depth of Field Highlights Solver playground!
« on: 2023-08-09, 11:01:44 »
Not really a daily build feature, since Corona 10 is already released, but we didn't have a dedicated playground thread for this, and we are super curious about your results, so here it is!

If you are rendering a scene where highlights are blurred due to depth of field (distant city lights, interior lighting, reflective/refractive objects), you can enable the new DOF Highlights Solver to get faster rendering.

You will find the checkbox in Render Settings > Corona > Performance settings. You don't have to change the Budget and Reprojection values as the defaults work well (but you are welcome to test them if you wish!).


You also need a camera with depth of field enabled.

Example 1 - Same render time - Click to open interactive comparison




Example 2 -Same render time - Click to open interactive comparison




You can learn more about the new Highlights Solver and DOF in general at:
- Corona Help Center
- Corona Documentation

News / Chaos Corona 10 Benchmark
« on: 2023-08-08, 15:03:27 »
With Corona 10, we released a new version of the Corona Benchmark app. 

The Corona Benchmark is an application based on the Corona 10 rendering core which measures your system performance by rendering a scene with Corona 10 without having to run (or even install) any other software. It can be used to measure how well your system performs when rendering with Corona and you can compare your score with other users' results to make sure your hardware is running as at its full capacity or just for fun!

Some other uses include:
- Comparing what improvements (if any) result from changing something about your hardware, BIOS settings, or Operating System settings
- Making an informed decision on what hardware to buy by making sure it gives you a notable performance improvement
- Stress testing the machine to make sure that the cooling can keep up with your CPU when it is hard at work (via command console)

Check out the following resources:
- the blog article - https://blog.corona-renderer.com/chaos-corona-10-benchmark-released/
- the documentation - https://docs.chaos.com/display/CRBENCH/Corona+10+Benchmark+Help
- the Benchmark download page (Windows and Mac) - https://corona-renderer.com/benchmark

News / Corona 10 for 3ds Max and Cinema 4D released!
« on: 2023-06-23, 10:38:29 »
Chaos Corona 10 for 3ds Max and Cinema 4D released!
Let yourself be driven by creativity, thanks to Corona 10's focus on giving you a smoother workflow and more artistic options so that you can achieve the results you want!

Full details and download: https://blog.corona-renderer.com/chaos-corona-10-released/


  • Easily add cracks, dirt, stickers, etching, embossing, and more thanks to individual control over the material channels (Diffuse, Displacement, Metalness, etc.) affected by a Corona Decal.
  • Fly cameras through smoke and clouds, or have them half-submerged in water with accurate rendering from Cameras inside volumetric materials such as those from Phoenix simulations.
  • Brighter, more accurate Caustics when rendering to large resolutions.
  • Greatly improved highlight blurring when using Depth of Field.
  • Easily find and adjust scatters, lights, proxies, displacement, and cameras using the new Listers.
  • Apply the same Triplanar, Color Correction, or Mapping Randomizer settings to multiple maps at once with new multi input and output options. No longer will you have to edit multiple nodes or spend time setting up control nodes to keep different maps in sync.

For this release, everyone gets a full 30-day trial period, even if you have used a trial before, to give you time to try out all the new features.
Remember, you can read about this release in detail over at https://blog.corona-renderer.com/chaos-corona-10-released/

[Max] Daily Builds / Camera Inside Volumes Playground!
« on: 2023-03-02, 13:23:30 »
A new feature added in our Chaos Corona 10 for 3ds Max daily builds now allows you to place a camera inside volumes!

Add volumetrics to your scene such as smoke, fire, water, clouds etc in the form of a .vdb file (fire/smoke), or just an object using a Corona Volume Material (smoke/fog) or Corona Physical Material with refraction and some volumetric effects enabled (water/other liquids/glass). You can then place your camera inside the volume and it will render fine.
Optionally, you can enable ''Camera Physical Size'' in the Corona Camera. This lets you place your camera at the border of two or more volumes and see the volumetric effects as expected (an example of this is partially submerging a camera so that you can see what is outside of the water and underwater).

See:
- New Volume Resolving in Corona 10 article in our Help Center
- C4D Playground Thread

Go ahead and share your results here. These are some of ours ;)

[Max] Daily Builds / New Corona Lister Feedback
« on: 2023-02-17, 18:06:41 »
Hi all,

In Corona 10 daily builds we introduce a reworked Corona Lister 2.0. Here are some of its features:
- The old version could only list lights, the new one lists lights and cameras in separate tabs.
- If an object has instances, they are displayed in a nested list where the top-level item controls the common parameters (such as light intensity).
- You can control instance name and selection individually per each sub-list item.
- You can select all instances by selecting the top-level item.
- You can hide and unhide columns.
Note #1: We are aware that the UI needs some more polishing - for example, some checkboxes should be centered.
Note #2: We already have some further improvements on our TODOs, so stay tuned for updates!

We are curious about your feedback: Is everything working as expected? Would you like to see some improvements in the UI and functionality? Is this something you will be commonly using in your projects?

Thanks in advance!
