[Max] General Discussion / How to match real-world lumen lighting output in Corona with IES files

« on: 2025-08-21, 15:07:04 »

Hey everybody,
I have a question that I’ve been trying to figure out for a long time:

Let’s assume I received a 3D model from the lighting manufacturer along with the real IES file of a light fixture. In the technical description of the fixture, it says that the light output is 500 lumens.

Now, I import the 3D model into 3ds Max, apply a Corona Light, load the real IES file from the manufacturer, and enter “500” as the lumen value in the Corona Light settings.
For this example, let’s assume that this is the only light source in the scene.

My question is: What are the correct values in Corona Post Processing (such as exposure, contrast, ACES, etc.) that will ensure the lighting output is as accurate as possible compared to real-world lighting?
In other words, how can I know that what I see in the render actually represents what 500 lumens with this IES would look like in reality?

Hope that makes sense.
Thanks!
Shaked

Nothing planned at this time, but you can add your vote to the Ideas Portal at https://chaoscorona.ideas.aha.io/ideas/CMAX-I-208

Thanks - I've posted it and I post it here as well just for people to see as well:

As corona slicer getting more and more popular among the corona users community,
The need for the coronaslicer support in Vantage is getting bigger.
The corona slicer is a fast and wonderful solution and many times replacing the old Boolean prompts.
And now, as the Vantage is getting supported by corona - which is a game changer -
Those two features need to be integrated together. It's like "half work" is done if the corona slicer is not supported.
Yes , I know that you have a slicer in Vantage - but the functionality is not the same while applying it in 3dsmax and it doubles the work if I need to start make it again in Vantage...

Please Please consider it !!!
Thanks,
Shaked.

Will be any support to CoronaSlicer in Vantage? We are very proud of the CoronaSlicer because it resolves so much problems,
But the problem now is that it not supported at Vantage...

Are there any Corona to Vantage updates?
Especially in Corona color-correction terms , it's still not smoothly exported to vantage.

Hey guys, really appriciate your hard work !
Really excited to see the new version and the support for Vantage.
Unfortunately, this is the result after exporting to Vantage (attached the vantage result and the corona result)

Fabrics tured out weird and floor turned out black.
Some textured got rotated like Diffuse and Bump of the same texture.

Is there a way to make the changes in Live? or its only "offline" vantage?

Thank you !

[Max] I need help! / Kelvin temperatures are not realistic?

« on: 2024-03-27, 22:33:53 »

Hey guys how are you?
While I'm planning the Interior lighting in my project - I find out that the kelvin temperatures are not realistic...
3000K looks wayyyy too orange. I disabeled the tone mapping, but it still not looks like a 3000k lighting...
For getting the realistic effect of 3000k I use 4300-5000 in corona light.
What am I missing here?


Thanks !
