Interior Rendering But Without...

[holle]

Hi vancliff,

the main reason for this is that most romms have windows ;) ,
also rooms with more light/brightness are easier to render with gi.

Maybe you have a stripped down scene of what you want to achieve?

if you want to lighten a room without using a window in it, then, you should use as many lights as possible. also, you should make many "include" and "exclude" in the lights scene tab.
in your case , the main problem will be shadows.
a complex scene with different objects " a room for examples", need to have one main light with a shadow activated , and many lights with no shadows and sometimes no speculars to brighten the overall objects.

this is why most interior works use windows.

are you thinking about a closed toilet room for example? :)

rely on existing case, where and what is the light source ( as in reality), then fill with small omni with no spec to brighten things up and ad some ambiant occlusion if it lacks some shadows...

[vancliff]

I have been trying to render something like in the picture but is giving me a hard time i am using global illumination with different parameters but i would like to know how to do it with normal light illumination because in the other way it takes too much time

[vesalus]

an omni behind the camera, aera lights up maybe an atmosphere object ( dont remember the proper name) the trick you mentioned will probably work if you think about your rim lights as a window if you see what i mean... ( kinda late her, hope i'm understable)

these sound similar to what you're looking for -

these are 2 internals as part of a set i did several months ago. The lighting is pretty simple, generally -

* local direct/point lights where you actually see lights in the scene, all attenuated.
* a single infinate light outside as the sun, with an area shadow
* 1 or 2 low light emmitting ambients with soft shadow maps.
* Global AO

and the gi settings -

strength - 100, pre-pass - 1/2, accuracy - 70, diff depth - 1, stoc samps - 500, min - 50, max - 400.

same difference applies for rooms with no windows.

These rendered on 3 year old xeons @ 3000 pixels in about 2 hours each.
