Hi all
I'd like to get some halp on this one:
As we know exterior dayligh and interior does
not work very well in lp.
My problem is this: I have a foyer wit glass that
looks outside in a big atrium with tables and trees.What i have done to get the daylight in the foyer is build external 3d faces and change theyr
prop to OPENING in the surf. process. to get the light in the exterior and set the glass face (inside ones) of the foyer as windows, hoping
to get light in the exterior and interior at same time. Is this allowed in lp? Is this the right way
to set the lighting?
I will have to run a short animation of it, so i cannot run two solution and merge them toghether.
Any suggestion appreciated.
cheers, Luigi

Hi,

If you can post your LP file or even just a screen shot to actually see the environment, this would help in assessing what is the best appraoch to use. Having 'planes' designated and openings on 'open spaces' of the scene is a very good approach however for some environments this is not ideal and the old approach of model surface investigation and light transfer analysis is desired. This means that you actually have to delete polygon faces and designate some surfaces properly for eventual processing of a 'split' environment for computing 'interiors' as well as 'exteriors'.

I did post an >Lp and 'Merged LS' file in the old Discreet forum to demonstrate my approach. As everyone knows, the tone mapping situation is the only thing that's going to have to be adjusted. Anyhow, film and video automatically respond this way anyway when it encounters extreme luminance(exceeds its own dynamic range).

Let me find this old file and hopefully, Jeff would let me post it here
