hi boys, i've problem i need to lighting this room.
there isn't windows and the effect with lumi panel isn't good (ithink).
i want a global lighting but is very difficult
who can help me ad sharing the scene?

I think You should try Lumi Panels.....
btw
New Kray have special button now for hide Lumi Panels from camera and reflections.

You can iluminate with lumi panel withouth problem.
I dont know what you need, about artificial light... add light where you need.

This is a fast test only adding more power multiply and photon multiply.

You can control thiss easy.

Accordling to your ilumination.
If need to iluminate dark zone is better adding more lumi panel for realistic results.
And you have problems with the mesh...

for final render i've used lumi panel but is a big numbers of panel so if this is the correct way i use it anyway!!!

i want test idea....in afternoon post the render!!

zohan you can post a a wire frame for see your distance panel

janusz where is special button?

i've tested using a grid plane with plane as lumi.
see the attachment but i think the lumi need a correct position into the space.
this is a fast test but isn't good...render time 19min and lighting very flat.

it's important move lumi panel one at time

I don't know what size you're rendering at but a render like that shouldn't take more than a minute one medium setting for 1000 x 500 pixels - give or take a bit, but 19 minutes, no. Maybe you have a liiiiiiittle bit of (blurry) reflection on all your white walls? If so, just set this to zero.

Then another tip for your lighting: filling up the whole room with completely evenly spaced lumi-panels will give a very dull image, as it should do, because if practically the whole ceiling is a luminous panel with constant lightness then there will hardly be any shadows. Try putting only 10 to 15 panels that are smaller in size (50 x 50 cm, for instance) just to get a feel for the difference in lighting - you might have to crank up the luminosity to 5000 percent but that doesn't matter, as long as it looks good. Filling up a whole space with a very regular grid of luminous polys has always produced boring images for me.

thank's for trips
we are working with a sequence of work in scene witout windows so we want found a good setup quality.

Nico i not change nothing in your scene, is all same that you share.

I only add Kray photon multiplier to your Lumi object and too i add soe indirect light on floor shader to increase bounds and take more light.

What else do you expect from a white room with white lights?! The problem is not in Kray setup but in your scene - you need to add materials, objects, colors...

oh jure it's ok...i've worked on complete scene with materials an objects but i can't sharing all.
it's a terminal of airport - drink and fast food....the global lighting in gate is all flat + interior lighting.
