advanced rendering for AutoCAD
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.
Sky intensity: .009
Sky intensity: .5
same as b except brightness at 0
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.
