Here is interior utilizing giant area lights. LightUp produces very subtle lighting.... I am very impressed with quality of it. Still renders are on par with mainstream render engines IMO with benefitt of moving in real time....I did quick test animating it and it looks great. Unfortunatelly the file is huge so I can't really post ti anywhere at mo.

Very beautiful..!
what do you mean with "giant" area light? You put one in front of the exterior glass? If so why not using sketchup sun?

I supose it could have been done with sun but would have needed to turn building around till have it in right place. ;)

I have tried to reproduce your method with a simple big "area light" in front side of the window but did not achieve a good result.
What are your settings for rendering and for the area light?

Hi archigrafix,

I've attached the original model so you can take a look. It is largely using sunlight - to get those nice slatted shadows - but in order to get light to the right side wall, I added a large area emitter just outside the window. Its simply a large rectangle painted with skyblue and marked as an emitter. (NB I've placed the emitter is separate Layer thats turned off.)

Enjoy,
Adam

That looks very good indeed.
A few questions:

1. The LU render shows the hidden light panel - I guess I can turn the opacity of the material down to 1 or 2
2. What is the function of the irr. cache in this scene ? is that for the glass material.
3. Does LU takes advantage of multi core cpus or just one thread ?

Yes, that would work. Or you could make the light panel a Group and hide it. LightUp will honor Group/Component/Layer hiding but not individual faces.

Yes, Its placed near the glass panel so it captures the lighting at that point and is used by the glass to reflect the room.

Yes, LightUp takes advantage of as many cores as you have available.
