Interior light settings

[David Nisbet]

I am setting up an interior animation and would like some help on lighting.

 

The issue I am having is that I would like to find a better balance with the environment light coming through the exterior glass.  The space, particularly the ceiling, feel dark to me considering the large amount of windows lighting the space.

If I increase the sky intensity then it completely washes out the mullions which are important for me to show.  I also would like to see the clouds through the glass which is shown on other views. The cloud image is a planar map to a surface outside the glass. 

 

 I'll upload a small sample of the animation for an example as well.

 

I am using the sun, background at visible sky intensity at .001, interior lights on and sky at auto.

 

TSTC-1a:

cloud .75

sun 1

Sky intensity: .009

brightness: .30

 

TSTC-1b:

cloud .75

sun 1

Sky intensity: .5

brightness .30

 

TSTC-1c

same as b except brightness at 0

So how did this guy get his exterior glass with a view and still maintain sunlight effect through his windows?. Short of placing a billboard outside my window I can't achieve any view of the sky.  Am I missing something?

You can ask him yourself on the IRender nXt forum.  His name is Boothy-- probably best to try to friend him and send email.

 

In general, you can set different backgrounds using nXt.  In this case, changing the visible background should work.  Anything with a spherical or cylindrical mapping will work.  I recommend using HDRIs-- or converting standard bitmaps to HDRI using the Widget tool-- but in a pinch a standard RGB bitmap would probably work OK.

 

One thing which may be confusing you is that the WalkAbout background is designed for a planar projection only (as I recall.)  You'll need to use the Background tab under Lighting.
