LightMix - how to do and play (just for 1.5 Daily Build)

[Tiago4D]

Hi I´ve maded a single tuto for the new LightMix

Is really a great idea this new update :)

and here is a demonstration of this

[amitshneor]

indeed its a powerfull feature !

but, if there is a way to apply the changes you made to the light passes in the mixer to the lights
themselves in the scene, it will be awsome.

also , the lightmixer pass appears only when there are several light select passes chosen, so how can
i render lets say a sequence of the lightmixer pass itself?

hope to hear from developers also !

Go GO Corona !

Wow! very exciting!

I wonder if it possible to make 360 viewer with interactive light controls? That would be awesome.

I am sure it's possible. It's just blending different images. ;)

Will Corona VR app have such functionality? Although i'd be much more interested in regular 360 viewer with Corona LightMix support.

I think thats is possible do the interactive light on an html5 or flash format.

Hi All!

I made a new video showing the new on lightMix and color temperature.

Hi All,

I´m thinking about lightMix and Isee that the button of creation of Light mix elements  dont is organising on alphabetical list, would be good on alphabetical sequences.

Hi
Is there a way to render once and save more than one lightmix result?
Thanks!

[TomG]

Yes, that is what LightMix is intended for :)

Render, adjust LightMix to your taste, save the image from the VFB. You can also save the LightMix setup with the Save option in the LightMix tab. Adjust the LightMix to something else, save from the VFB (and can save the LightMix set up). Repeat until you have enough versions of the image :)

You can then render the same scene from a different camera angle, and simply Load the LightMix settings and save the image each time, to replicate the same LightMix setups - this is scene dependent of course, as it requires the same lights etc as used when the LightMix setups were saved.

[ihabkal]

Thanks Tom,
What I meant is to send different scenes to the render farm to be DR rendered while I am sleeping, then wake up and find Corona saved each scene twice or more once as a day scene and once as a night scene without me having to manually save for each variation, and without Backburner rendering the same image twice for two lighting solutions...

LightMix it's post-processing task. So, you can play with it when your rendering is finished.
The solution to all these similar requests will be the standalone App.
In the App you will open your RAW Corona exr file, and you will add denoise, glare (in GPU, I think), and create all your 100 different LightMix
 We must only to wait.

[Frood]

The solution to all these similar requests will be the standalone App.

Not for what ihabkal has asked for.

And I´m surprised that there seems to be no feature requests for this yet (forum + bugtracker). Do I miss something? Currently you can add multiple LightMixer elements but all seem to share the same LightMix settings so it´s useless to do so.

If every LightMix render element would get it´s private mix setting this great feature would get qualifyed for automated and "deterministic" workflows. I was under the impression it´s already working like this and was astounded by the fact that apparently it doesn´t :)

Good Luck

[PROH]

Yes! I actually did mention this in the Daily thread, but I didn't make a dedicated request. The ability to save and load presets makes a good start of what you're talking about, but surely this would expand the possibilities and efficiency.

so +1 for this :)

[alexyork]

I'm sure it's been asked a bunch of times but we'd LOVE to be able to animate the lightmix values in the VFB and save out to an image sequence........ :)

[Frood]

but I didn't make a dedicated request.

Ah ok - lost in the usual daily thread noise. Would you be so kind to create a proper request on mantis, PROH?

@alexyork: This will definitely get a job for the standalone application cecofuli mentioned (and it can be currently done easily by rendering out the LightSelect RE´s EXRs and compose them). BTW: Wondering if there will be some kind of contest to find a proper name for that postpro cexr application :)

Good Luck

[PROH]

Done :)

[Tiago4D]

Hi All!

I was thinking of an element just to use certain lightmix preset,

maybe "lightmix_setup"

maybe not controllable just to use preset saved in the edit of the ligth mix

What would you think of this idea?

B.R.

[Frood]

Hmm I was never (and never will get) an advocate of additional external files. Too much trouble potential when rendering automated anyhow, if they are not dedicated scene assets and treated like this.

So the hole load/save part is nothing like a bridge to the standalone application in my eyes; for me personally quite useless because the process is not able to get automated. I want a scene, I want to submit it and I want to get the results directly without fumbling with external files or applications.

Your idea (ignoring the external files part :) could additionally help to save framebuffer memory when rendering - say - 10 different lightmixes. So they could be processed in the post stage separately like denoise (using settings only as you described which would be stored in the max file) and not using fb memory each while rendering. But different lightMixes with different settings would have to be handled in a way like that anyway (obviously or hidden), using just one shared fb "slot", everything else makes no sense imho.

I would prefer that 1000 times over any external cEXR solution with load/save of config files. Well, just my thoughts,

Good Luck

[PROH]

I think that at least scene dependent stuff (light mixer presets etc.) should be saved in the scene/Max-file, and not as an external file.

Regarding things that are not scene dependent, it can actually make sense to use external files.

Hi PROH!

I´think that is solved! Or will

That´s something different from what was discussed here. It´s about automatically adjusting scene lights and colors so that they match the current settings from a (the) lightMix panel with the effect that the beauty (without mixing lights) looks like the current lightMix when rendered. It´s not about having multiple lightMix setups with different settings simultaneously.

is the way Frood!

with this just "scene_selected" element and voilá!

Hmm... Nice feature for sure. But I too can't see how this will solve the "problem" discused above.

Or did I misunderstand something?

[steyin]

Not sure if this was covered entirely, but if I send a few views to render in backburner that have various lightmix settings, as well as VFB settings, how do you ensure they each come out correctly? For example, I have a scene with multiple suns for different views and have tweaked the lightmix and VFB settings for each camera (and exported the settings), yet when rendering to backburner it cannot recall those settings. Even if go to the backburner VFB and load them, it does not save the render with those settings applied. I get the render elements for my environment and the sun, but not the overall correct composited image as a final result. Not really sure what to do aside from just rendering one by one and saving manually without using backburner, but I can't do that when I need to render all these over night.
