Multilight?

[raducoc]

I think will be very great to add a feature similar to Multilight from Maxwell. Render once and after that tweak the source lights and get an infinity of light posibilities.

Searched before. The search engine has returned only three threads with the word multilight, but no one with multilight feature request. Or Im missing something?

ANYWAY PPL.....multilight is a must have feature...

[OnoSendai]

must have?.. it was only invented recently by the maxwell dudes!

[Kosmokrator]

invented? hehehe come on Nick u Can Make some Magic.....

i think and fry render have this feature....he calls them layers...or something!

[OnoSendai]

I'm not saying it's hard.. i'm just suprised that people consider it a must-have feature.

[Maluminas]

Well it would save a lot of fiddling and tweaking and test rendering on scenes with complex lighting.

We all agree in that. But if you are serious about that. why dont you render the image X times and compose the images yourself?

[StompinTom]

Deus, you seem almost cynical about having a multilight-like feature in Indigo.
for instance, you could actually render two pictures with different materials applied to an object and blend them together in photoshop using layer transparencies and masks instead of using the new blend material but having the blend material seems like a good idea no?
dont take this as an attack, but as an observation. i just think youre reacting oddly to a simple feature request.

i think there are certain advantages to having a multilight feature:

im sure it would be faster (even by a little bit) than rendering separate images say if Indigo saved the influence of each light group per pixel in the Indigo image format or something like that while rendering.

theres also the tonemapping issue, youd have to tonemap each image separately the exact same way which, with reinhard tonemapping, i think would be a little difficult. sure you could do it in photoshop, but as with many features, its all about saving time and getting things done more efficiently.

related to that, also the simple convenience of having everything in one file/place ready to be fucked around with.

so, if its not crazy hard to code and if it did turn out to be worth the (extra?) render time, id be all for it. im not even gonna get into the 'what new feature is the most important for the next release' debate.

my two cents.

whatever the future features, i think Indigo is already catching up quiiiite quickly to Maxwell and Fryrender, as much as i dislike to compare everything to the already "legendary" Maxwell quality.

im totaly agree with this StompinTom!!!

No you cant. That was the most stupid thing i have ever heard. If you had a material mask yes and also percentage of pixel covered etc you could do that

But

Blending two lights however doesnt require any changes. anyone that is serious use HDR/IGI etc anyway. So no.... its NOT a must have feature. Material blending however is. If you are gonna do comparisons like that better get your stuff together

I am cynical about the way you pose the request. Not the request itself. I want the multilight feature myself.

Nite nite

I think he was just joking there.
Anyway I'm not sure I understood exactly how multilights work, but if so yes that would be a nice feature (maybe ot a musth-have but nice)

[raducoc]

Yeh, also I think this feature is a Must Have! Letme explain better: Indigo is an unbiased renderer and have BIG render times. To obtain a good result you need to render your scene some hours (in some cases, days). Now, think you want to make a simple animation of an interior room simulating this room in diferent light conditions. Day, night, all lights on, all off, etc. To do this, rendering the same scene with different light conditions and without MultiLight will eat VERY MUCH TIME. For a few seconds of this kind of animation will eat maybe an entire month to render and render all the frames needed!

Now, please take a look at the multilight video gallery of maxwell:

This examples are very impresive:

and here is a better explanation of the light animation process:

For a few seconds of this kind of animation will eat maybe an entire month to render and render all the frames needed!

Basically you need only as many renders as lights-you-want-to-mix. The frames needed for the animation could be exported from compositing progs or even photoshop (mixing the renders with differnet opacities and "screen" as blend-mode).

Of course i would like such a light-layer feature too. Maybe an IGI-Manager where tonemapping, glare and light-layer things could be edited would be cool. (dont know how boring that would be to code tho )
