Sun & sky with emitter's , It's Possible?

Hi guy's

Well i have a little noob question ---

Its posible To use Sun & emitter's In Blendigo..

This is more explicative , it's rendered with luxrender (it's not my scene XD)
But the environment it's a sun , and the lamp it's a emmiter

If you want to render your scene only with that mesh lamp set it to "none". The "physical sky & sun" environment will turn your sun lamp into a "sun" and create a shaded background to go with it.

Also, in this case, you sun should be set as layer 0, and your lamp emitter to layer 1 (by default), which means just like luxrender's lightgroups you can control them individually.

The environment refers more to what i would call the "world illumination". An env map will "wrap around your scene" and light it, physical sky and sun does relatively the same thing and well none leaves the light up to your mesh emitters.

You have to remember though that no environment setting will keep you from using mesh emitters. You can always use both at the same time.

164lndj, yes you can render with both - make sure you get the "brightness" (emission scale) correct on the lamps though, I had a problem where the sun was so much brighter than the lamps that you couldn't tell it was on.

You could always play with the sliders during render, by turning layer 0 completely down only the mesh emitter should shine through, so you'd know if it was on or not

Hi ,

sorry but I can't understand , I try it but don't work ( sun light and emit mesh light in one scene ) .
I use sun light ( layer0 ) and emit mesh ( layer1 ) .
I try environment : Phys. sun+sky , none -mesh emit , environment map

Be sure that you are not using the Reinhard tonemapping. If you do, then try with camera or linear instead.

Can you post your scene?

Thanks , i change the tonemap and good.

Borgleader thanks

Hi guy's Thank u for ur response's

Well finally i have a "render" XD

At this moment are 2000 Spp [6 hours] & the noise still in that tonemap "Ektachrome-100-plusCD" It look's very strange but nice ..

The layers and that stuff work's

But i'm confussed with something.The Emission Scale seems like it's not working ,
It have :
Gain:3
Value:4874
Gain multipler: 10 ^ 5
Temp:3946
When i Change this values , the lamp doesn't turn it on , only with The "Gain" In the Light Layer's

It's this correct or i'm kinda drunk ?

[Borgleader]

Well it somewhat makes sense considering the sun is one helluva lamp

You could always turn the layer 0 gain down. Nice scene btw
