Light Tests

Hi,

i am looking for any light test - lights setted in Blender for Indigo.

I've got a problem with placing lights in my scene, so i would like to see something for example.

Is it possible to use SUN and EMITTERS in one scene ? ( i tried and i get strange view)

If i use only sun behind window my room is too dark, if i use only emitter i cant get effect of dropped sun rays through the window.

Is there any difference in using single or using more than single SUN ?

Peace!

you need to use extreme energy to make the emitters visible at all with sun

They're too dark for standard contrast. you'd need HDR (like your eye can perceive) to see a lightsource at ALL during sunshine.
So, you need to make the lightsources unrealistically bright.

ok, i tried it and it works but after that environment behind window is darker or even very dark and it looks not nice

Is it normal to use this kind of light setting ?

I ve tried to use exit portals for make sun light brighter but it doesnt work.
Could someone give me some simple example with cube, hole in the cube where camera is inside the cube and there is a nice, realistic light inside the cube ?

What kind of lights and settings i should use for realistic bright day light ?
Is it smart to use more than one sun ?
Is it possible to make power of sun higher ? I cant find any slider to change it.

Peace!

well, that's simply explained: same what happened before with your lightsources, now happened with the sun&sky

You have to tweak it, until both have roughly the same brightness

Also, switching to Camera or Linear Tonemapping might help you with that

It's not only not smart to use more than one sun but even absolutely useless: ONE sun per scene: That sun&sky model is a basic model of OUR sky and not of ANY planet in the universe

"Brighten" the sun by "dimming" the other lightsources again

Exit Portals wont make things brighter. They just make them faster....

Aye to the tonemapping, but also you can put meshlights on a second layer once you have a close-but-not-so-good match with sun, and play vith layers values ?
