Hi all,
I need your help to illuminate an interior: look at this model



1. more than a room, all visible at the same time in a view (it's a showroom)
2. no windows to get light from
3. ceiling is variable from 3 to 8 meters high
4. there is not a specific project for the lighting (spotlight, diffuse etc)
5. I need to produce 15 views, 1920x1080 in about 36 hours (have a dual quad core and 8 Gb di ram)

I did this attempt:

1. only skydome, without the ceiling layer (It was added in postproduction). Very fast rendering, but the images are very flat.


2. better material (a little bit more reflections) for a slight improovement.

3. all the ceiling mapped with an mxi image (like a lot of spot): interesting effect, but very very very very slow! maybe with a computer from NASA.

4. I tried to put a lot of lowpoly squares (10x10cm) with emitter material as spotlights across all the model (about 40 pieces). The effect is nice but need also a lot of time to calculate (12h per image).


At this time I'm very confused ...
So, which is the best way to get the last image look (it's ok for me) but in 3-4 hours per image?

Thankyou! and sorry for my bad english...

Everything looks miniature. Is the scale correct?

[polynurb]

not sure if you can modify these ~40 low poly emitters to render any faster.. (you didn't use multilight did you???!!)

but it should help to slice/bool the scene up into the parts that are actually visible in the seperate renders, and just close any invisible openings with white walls, so you don't feed the entire model into maxwell every time.

Bubbaloo: the scale is correct (meters)

Polynurb: multilight is inactive, but to slice the scene in multiple parts to render independently is probably a long work too (you have to manage settings, merged objects and so on for three or four times...).

Thank you for your reply!!

[Bubbaloo]

It sounds like you might need to farm out these renderings. 15 in 36 hours is crazy! Doesn't leave you much time for scene setup.

[metheny1001]

I know that is a bit crazy to achieve a good result in so little time, but a renderfarm is not an option at this time ($$$).

So, the question is: which is the best compromise quality/time in term of light setup for this kind of scene?

Skydome? Emitter? Both? Mxi? One large emitter? A lot of small one?

Cheers

I like the "only skydome" rendering. Sure, it's a bit flat, but it's neutral and it renders fast ... you could try to increase the contrast, but maybe some materials will become too dark then.

Nobody else?

Sorry but I think Maxwell is not the good choice for the kind of work you have to do in the time you must do the job. Less than two hour per render and 15 render, I didn`t waste the precious time you have and I would render with an unbiased renderer.

Ok, if there is no other way... ;(

Thank you for your effort!

Good render!

There is... another way (Gollum )
