[Max] I need help! / Re: Reflection slot of CoronaRaySwitch material affects GI

« on: 2022-11-30, 07:15:34 »

The image was showing CESSENTIAL_Indirect RE

Disabling the reflection is definitely not the right solution for me. But even with disabled reflection of sphere the CESSENTIAL_Indirect RE looks wrong. Please have the updated render with IOR=1.0 and test scene attached

Hello,

The subject and the attached image should be self-explanatory
Is there any way to avoid it?

Thanks,
Dmitry

Sometimes the resetting Corona (switching to Scanline render and back) helps

That will work as well. Thanks!

Sometimes to minimise the post work I put the proper sky background in the scene as a CoronaLightMtl
I see now that the CoronaSun position does not reflect the physical position of the sun but rather serves to define the light direction (yes, that's the reality)
So, to get the sun visibility together with the Bloom and Glare effect I have to make the background transparent a little bit or to put the Corona Sphere light in front of the background
Just wondering if there are more options )

Unfortunately, that does not help

The only solution so far is making the object a bit transparent through Opacity map

Most of the time for vegetation we have to adjust the Output parameters (Output Amount, RGB offset, RGB level) of each bitmap in Multi/Sub-Object material at once
In this case we use the following script

You should try it )

[Max] General Discussion / Re: Spot light beam angle and CoronaLight Directionality

« on: 2021-03-30, 11:08:33 »

I would love to understand more about the Directionality parameter.

If it's not linear is it possible to correlate it with the light beam angle of the real lights?

I attached the scene with 3 IES lights taken from the Philips lighting website:
https://www.usa.lighting.philips.com/support/support/literature/photometric-data#led

My question is How to adjust the Corona lights to mimic the similar beam angles? Only by trials?
Any help will be appreciated

Not sure if I understand your question correctly, but I would say that directionality 1 = 90 degrees beam (the light shoots straight from the light object's normals - like laser).

Hi Maru,
Let me re-phrase my question.
How should I adjust the Directionality parameter to match the Beam Angle of 60 degrees from the light's technical specification? Will it be (1-60/90)?
Thanks!

« on: 2021-03-26, 07:16:00 »

Hello,
Is it the linear dependence between the technical characteristic of the light source and CoronaLight parameter? Let's say setting the Directionality to 0,5 will be physically correct for 90 degrees beam angle?
Thanks

[Max] Daily Builds / Adding Physical Camera to Distance Texture

« on: 2021-03-11, 06:50:26 »

Hello,
In the latest daily it's possible to add only Corona Camera origin into the Distance Texture
Would you consider to add the Physical Camera as well?
Thanks!

The feature is very helpful, indeed

However, would you please update if Corona team is working on the issue about UVW center transform for Randomizer

https://forum.corona-renderer.com/index.php?topic=32263.0

Thanks!

Yes! Big big hope!

So hard to make the randomised tiled flooring with one not seamless texture
