[Max] General Discussion / Unify Corona and Vray assets

« on: 2025-02-03, 23:17:39 »

Hi Corona Team,

We frequently use both Corona and V-Ray interchangeably, along with Chaos Vantage. I was wondering if there are any plans to unify materials between Corona and VRay, perhaps a shared Chaos Material, since they essentially serve the same functions.

The same could apply to proxy meshes; instead of maintaining two separate versions, having a single ChaosProxy for both would be much more efficient.

Has the development team considered this for future updates?

[Max] General Discussion / ***BUG Corona Render****Chaos Corona Action.

« on: 2025-01-21, 23:21:21 »

This bug has been around for years. In some cases, users can work around it by clicking "OK," then pressing the render button, stopping it, and switching back to interactive rendering.

However, at times, there is no workaround, clicking "OK" does nothing, and if the user tries to start interactive rendering again, the message reappears in an endless loop.

Additionally, the error message is often incorrect, as Corona is not actually rendering when it appears, making the warning misleading.

Possible Fix:
When the user clicks "OK," the system should check for any active CPU cores running a render process and force them to stop, allowing new commands such as rendering or interactive rendering to proceed.

[Max] General Discussion / Best Practices for Corona Proxy

« on: 2024-11-27, 05:06:45 »

Hello Corona Team,

I have a question regarding best practices for using CoronaProxy. Like most users, I would like my file to open as fast as possible and also efficiency to transform vertices and parsing while in the rendering process.

Would you recommend enabling the "Keep in Memory" option for all proxies? My render servers are quite powerful, with half of the farm equipped with 128GB and the other half with 256GB.

Thank you.

[Max] Bug Reporting / Light Mix ****BUG****

« on: 2024-11-09, 06:55:01 »

Hi Corona Team,

When lightmix is enabled and if the user sets a Kelvin color (e.g., 4800K) using the Corona Color Picker, closing and reopening the color picker causes it to default back to 1700K.

[Max] Resolved Feature Requests / Alternative display option for unsupported materials

« on: 2024-11-08, 07:46:00 »

Hi Corona Team,

The 'red warning override material' can quite disruptive during rendering production. While I understand it’s intended to help identify missing materials, it can be easy for users to overlook. Archvizers often don’t have the time to address every material issue that comes in from external models, like those from Revit, SketchUp and Vray. Additionally, the Corona Converter doesn’t always handle the conversion of every material, which can leave us with the red warning material in final renders.

While I appreciate the warning feature, perhaps this red glow could appear only in Interactive Rendering (IR) rather than in production renders. In production, it would be more helpful if missing materials defaulted to a gray, which many of us commonly use when we don’t have time to texture a model fully. I believe this would align with how many Archvizers work. Also I would exclude the warning material from Lightmix or eliminating the light glow.

Possible solutions could include:

Improving the converter’s capability to convert all materials from Revit, SketchUp, and V-Ray.
Making the 'red warning override material' visible only in IR.
Adding a checkbox in the converter to automatically convert unknown materials to gray.

Thanks for considering these suggestions!

[Max] General Discussion / Problem with CORONA Materials in Viewport.

« on: 2024-10-30, 20:12:57 »

Corona Team,

I’m not sure if you've noticed, but when you create a material and try to display it in the viewport, it doesn’t always show up correctly. Adding nodes like ColorCorrection, randomization, etc., causes it to disappear from view.

Another ongoing issue is with the CoronaTriplanar node, it doesn’t display at the correct scale in the viewport when the size is changed.

I know the the common response might be, "this is a 3ds Max issue," but are there any plans to address this with Autodesk and partner up to make the plugin work? I've seen Arnold users working with materials and shading directly in the live viewport, and it seems like some really impressive coding.

I don't think this requires a transfer of files. This can be easily replicated. Use Poliigon mats to test.

[Max] Bug Reporting / Material does not display on viewport - ****BUG**** Corona Render 12 HF1

« on: 2024-08-22, 00:39:18 »

When a CoronaSelectMTL is applied to a decal it does not display material preview in the viewport. Even when the "Show Material Preview" is checked. Please try this on your end this is easy to replicate.

I tested this with CoronaLegacy and CoronaPhysical

3dsmax 2024.2.1 Update
Corona Render 12 hotfix 1

I also tested with:

[Max] I need help! / CoronaSelect - Maxscript

« on: 2024-08-21, 23:11:48 »

Hi All,

Does anyone have a script that looks in the scene's material for CoronaSelect nodes and the toggles the CoronaSelect from 0 to 1?

I have decals that needs to switch from ON and OFF in the scene.

Thank you!

Anyone else having issues of some Corona Material bitmaps do not display in the viewport? I reported this as a bug a year I don't know what happened to that.

I am just wondering why a scattering system was created if there are robust scattering systems on the market?
