indoor lightning

[ARK_3D_bureau]

Hi

Why is my scene so lit up some where, when my ceeling is so dark, can any one help me, cant find the right light settings, im using vpay 1.46.15





here is the scene http://www.3dbureau.dk/temp/stue.zip

try place an omni in the middle of the room with far attuetion and low multiply. white colour

Try to imagine what a real photograph of this scene would look like. All the light is coming from 1 corner in your room. Try not to use bounce multipliers higher than 1. Instead, cranck up the multipliers of your lights.

But without lighting up the dark side of your room, you will always have this contrast between light/dark areas.

If you would post in the registred users area, you will get more help probably.

When you say placing an omni in the middle of the room, I assume you mean a standard Max omni. Wouldn't it be better for Vray to use a Vray sphere light instead?

If you want your fill lights to look real, place them in positions where in real life lots of light will bounce. For example use a large vray plane light just below the ceiling (1 sided, invisible) with a low multiplier. This will lighten up your scene a lot and it won't look very fake because lots of light would bounce of the ceiling anyway.

But for maximum realism, stay away from fill lights

Can I ask another thing. If I have two Vray lights coming in from a window with a slightly high multiplier the whole scene becomes so washed out in the shaded viewport that it's almost impossible to work with it. Renders come out fine though.

What am I missing?

Change the viewport properties to default lights - 2 lights

You can never adjust the scene lighting according to the viewports anyway, so with the default lighting on is usually the best thing to do.

That was actually great advice! Never thought about that one.

i´ve tried to get the best illumination for interiors and really the best way is using a standard skylight after precalculate de irrandiance map, but exist a big problem...........

it seems that vray don´´t like this kind of SKYLIGHTS because in a rendering process you maybe find this kind of warnings and your renders never finished good

"2005/May/24|14:47:37] error: UNHANDLED EXCEPTION: Rendering region (704,12-(720,192)
Last marker is at P:\dev\LocalVSS\vray\vrender\src\renderlight.cpp, line 300: VRenderLight::eval(), calling LightDesc::Illuminate()"

This happened with vray 1.09.03 and 1.47.15 versions for max6.

This looks like a BIG BUG but i have not solutions for this problem... maybe somebody could have it???

i post this because i think that this kind of lights emulate in a superior way and without so much lights in your escene (because it´s a global light) the real interior lightning and don´t torture in a hardway the render times like other solutions and don´t affect in a perceptible way the exterior assigned textures )
