Boost light interference?

[streamline900]

Hi:)
Boost light interference. (could be wrong terminology)
it's may be a fakie. May be gradient... By density of light?

For example:


I think it will be useful,because Many interiors,
especially with no windows and external lighting
look gray or colorless.

This approach will help to make the image more interesting.

This doesn't happen in real life, right?

[Ondra]

I don't get what it is....

[Polymax]

If in the interiors (without daylight) use the light with different colors, it will more fun :).

[streamline900]

Yellow - Orange (yes,for fun:)

[ecximer]

maybe I do not understand something?
is not it?

[iliyang]

Do I understand correctly that you want to essentially texture the directional emission of the light sources? All renderers already provide texturing the radiosity at any point on the light source surface. What streamline900 seems to want is the ability to also control the radiance emission at each point, i.e. the directional distribution. As far as I know, IES profiles only texture the intensity, not the color, right? I guess this could be achieved by attaching a (hemi-)spherical map to the light source. I find this a pretty reasonable feature request, and I can imagine that interesting results can be achieved with this. Does any other renderer have such a feature?

[Polymax]

I think in other renderers such either. And in the real world this does not exist, at least in the normal environment.

[streamline900]

The point is not that In real world this does not exist.
This is needed for the same, for which people use HDRI.
I think you will agree that the reality is different from the rendering.

No matter Fake it or not, the main thing is the result.

OK. In principle, and so, so good.

Continue to testing:

[Polymax]

I agree, that if there are additional art tools is only a plus. But, I think that you first need to finish the base.

[streamline900]

I absolutely agree.

No matter Fake it or not, the main thing is the result.

Keymaster doesn't like fakes, Corona is intended to be as physically correct as possible. You can do such stuff in post, right?

[Ondra]

I still don't know what am I looking at....

[maru]

From what he posted it looks like some kind of tone mapping (gradient mapping?) - light's colour changes with it's intensity. I think the only situation when this happens in real life is when there is some kind of coloured ambient light and a directional light that mixes with it.

How is this feature called in other renderers?
