Precalulating Lighting in 3.0.1? 2003-12-08 - By Charles Brissart

Hi,
the extra step is used to correct a number of issues with Global Illumination.
In particular, it avoid certain interpolation artifacts that were happening
with sky light on infinite plane.
It also improves that image quality in most cases.

Subject: [Carrara] Precalulating Lighting in 3.0.1?
When using any of the GI options, (caustics, sky dome, etc...) when you press
render first it goes through the "Sample Lighting" and we see a progress bar
run at the top of our screen. Since updating to 3.0.1 I've noticed that it
now
goes through the "Sample Lighting" and once that reaches 100% it starts a
second progress bar right under it that says it's "Precalculating Lighting".
My question is, what exactly is it doing? What is "Precalculating Lighting"?
I
know I've not changed the way I do anything so unless I've not been paying
attention, I'm assuming it's something new in 3.0.1 since I've never seen it
before.
There's no problem or issue with it I was just wondering what the
extra step was for. I figure it'll have to be one of the Eovia guys who
answers this one. Matt, Charles?
