hi,
is it possible to render an image with 2 lights for example,
and give out a pass for the lighting of each light separately?
over light ID or so?
thank and best regards
Jonas
LPM pass manager makes that pretty easy. It has an automatic ‘pass per light’ setup.

looks interesting. thanks man, will try it out.
but wouldn’t it be great to have a pass in Vray direkt? or is it possible allready?
best regards
Jonas
I guess it would be, but LPM works so easily that it I can’t see how it would be much different. It was originally free too, but it’s not too expensive for what it can do IMO.

It would render in one pass, hence consume less space, render faster and be more convenient to use i’d say…so i’d second the wish

Well that sounds perfectly reasonable so I will 3rd it

i d like that too!
Guillermo has his Multilight script, I think a lot of people missed it because the thread started right before the last server crash. It can be seen here Page not found – Evolución Visual – Guillermo M Leal LLaguno (scroll down for purchase info)
Well i’m sold. Bought.
multilight script requires a fair bit of work to get it going. I also have asked vlado many times about this option.
This would be an excellent feature.
Although, there are advantages to sending each light pass to a separate node on the farm. (no DR here, too complicated to wrangle given so many users) But that’s another story.
I have a general question regarding workflow for multilight. I’m working on a concert hall type space. I set up all the lights just the way I want them for the final render. There is a lot more light on the stage than in the seating. So the house lights and aisle lights are pretty dim.
But for a multilight setup would it be better to crank up all of the lights to the highest level I might need? It seems easier and cleaner to lower exposure levels on overbright images than to raise them on low lighting images.
And color… I suppose they all should just be white? Then CC them in post.
Any tips?
This is correct, yes. If the lights are too dark in the render, V-Ray will sample them less accurately, so if you brighten this in post, there may be a lot of noise.
And color… I suppose they all should just be white? Then CC them in post.That’s pretty much as you wish, I think.

Photoshop pases put together?
QUESTION about LPM &Guillermo Multilight.
You can render the lights in diferent exr pases en use the build in script composer to adjust the lightning right?
Lets say i dont want to use the build in composerscript from lmp or Guillermo mutilight and want to adjust this in photoshop what then?
how blend (screen,mutiply,exlusion…???) those pases in photoshop (no nuke or ae..)
greets:roll_eyes:
Linear Burn or whatever the additive one is.
Maxwell pdplayer?
I did a test yesterday with pdplayer for blending thoss passes together
and it works verry nice
is it possible to make a multilight export movie like in maxwell with pdplayer?
If you are referring to Maxwell’s “Realtime Interactive Emitters with Keyframe Animated Intensities”, then no, sorry. Pdplayer does not currently support keyframe animated properties, so you can’t animate the exposure or gain of a light layer.
hi, perhaps i have a tip:
to minimize rendering work and still get control over single lights in comp, you could make lightgroups of 3 individual lights in one rendering, each of them is a bright light with full 255 color. one red, one green and one blue light. this will make your rendering look like disco.
then in any compositing software, you can now isolate those color channels and convert them to white and then rework the colors as you wish in nearly realtime.
this way you can seperate 3 lights in one rendering.
the same principle of the multiMatte channel, indeed.
In fact, if one uses precise color values for the lights, and no decay, it should be possible to separate as many as one wishes in post, give or take a few decimal points of precision due to the sampling.
Something that may be worth investigating
this is what we normally use. But a built in form of that would be very nice…
Wouldn’t this totally kill any colour fidelity for bounced light (ie. bleed)?
