I have 2 questions regarding Corona 12 VFB:

1. I cannot see the effect of NVIDIA denoiser AI during rendering, although it was visible before.
2. I cannot set a value in LightMix lights that exceeds 100.
Do you have any idea if there are solutions for these issues?

If you need a value of over 100 in lightmix something is wrong in your scene and you should make the adjustments to lights in your scene rather than in lightmix. It will result in less noise and fireflies in the image. If i recall an old thread anything above 5 in a lightmix layer and youre better off making the adjustment in scene due to how rays and sampling work in Corona. I may have the number wrong but its definitely not 100.

Hi,

1. If you mean the NVIDIA AI Denoiser for production rendering, then it is known and already fixed internally.
2. Was it possible before (VFB 1.0)? Nevertheless, the above suggestions are valid, anything made too strong in lightmix is better to be adjusted in the scene - brighter light means Corona will allocate more samples for it, lending more accurate render, rather than less but afterwards made stronger.

Thank you for the answer;

This option was available in previous versions of Corona, even up to version 11, without any distortion or lighting errors when using a value of 200, for example, in some light sources (especially environmental lighting in interior spaces HDRI). It's worth noting that in version 12, I can set high values after saving the file and opening it through the Corona Image Editor, which made me wonder about the inconsistency in that.

As for NVidia AI Denoiser, I am asking about the reason why it is not activated on the image during the rendering process. It was available in previous versions, but now I have to stop the render to check if the time is sufficient for the render to be considered acceptable.

I hope I was able to clarify things more this time.
Thank you

Yes, exactly. This should included in the upcoming hotfix.

For the other point, I will ask around.
