Light mixer corona 1.5 .... Vray 3.5???

[Sbrusse]

This new VFB looks great indeed,
I would still wish to have some sort of light mixer, even if IPR will be implemented.
I'm more than aware of the sampling issues it will involve but ee have heavy scenes that takes a long time to render, even for few buckets.
The best for us would be leave a render go for a bit, mix things to achieve visually what we want and have a button that would "commit" the changes done in the light mixer to the actual lights in the scene.
That way, next time we render, we would have the exact same visual representation than what we had in the light mixer previously but with the right sampling applied.

Hope this make sense,

+1 This would speed up my workflow by so many times...

Yup, I agree with this. Once Adv IPR is out, this feature will become far less important

I don't see how a lightmixer becomes less important with IPR. Unless IPR gives you real time no matter the complexity of the scene...which I'd hardly believe it's possible yet.

hummmm

Do not understand how a system only recalculates the bounce of the light emitters, compared to recompute all, will be more "efficient".

Clearly I do not understand the process but in my head I understand that the lights are under one system that stores the result independently.

If he did, would not it be faster recompute to do it all again?

Finally watched and doesn't V-Ray already do that with the light select element?

[Sbrusse]

Well not as accurately (RTGPU is better though in that regards) but you would still need to save out all the passes and comp it in stead of having a few sliders and do it straight away in the VFB. Plus the noise level and aliasing will be off if you change exposure in your element passes, so it's definitely a clear plus to have it straight in the VFB.
Like Insaid, changing it in the vfb and have a commit button that would push all the changes into the lights so that the next render reflects the changes would be a suprime add on

The result would not be different though no? Unless you re-render with the changes applied to the light. Or did i miss something? The biggest part missing in the puzzle is being able to save all contribution of a light i thought?

That's exactly why I suggested to have a "commit" button, it would apply to the lights in the scene the changes that where done in the light mixer so that at the next render, the noise and aliasing will be perfect.

My hope is to be able to place all the lights in the scene, multiplier 1 with white, let it render for a couple of minutes and change the whole lighting mood through the light mixer to get the desire visual. During the mix, we might have pushed light x20 or more in exposure and change light temps but all that in REAL feedback, not progressive re-render with noise every 2 sec.
Once done, push commit and boom, the next render has proper aliasing and noise

So awesome!

Unbelievable!...meanwhile Vray's Bloom mask has been broken for 2 years... I didn't realize Corona was so good.

[glorybound]

I remember Lightscape doing this, I think.

Yeah me either, Corona seems really strong in terms of effects and VFB features, it really has the things that Vray miss drastically
