is sometimes a pain as we all know, i think i have discovered a new setup which i think works quite well

This is a work in progress of an old scene that i have attempted to light in many different ways over the past months, i have not finished the modeling as i have never been happy with the lighting so far

Anyway let me know if anyone is intersted in my light setup and i will explain

(rendertime - 48 minutes - needs higher samples though for final render) 3 lights in the scene

sorry the sofa belongs to twilight - i must replace it

Wow excellent lighting, is your technique very different that the others ?

Thanks daberman - basically the 3 lights are - sunlight (hard spot), one omni with soft shadows to brighten dark areas of the room and reduce artifacts and one omni with no shadows which is set to include only emiters which are polygons that i have set in the windows (hidden by camera) - this light is on about 800%

If you look in the mirror, you'll be able to see those polygonal emitters in the reflection of the windows. :shrug:

Even though this light setup looks good, I'll stay away from it since its not how nature works and could end up making an image looking rather unrealistic. To make renders as real as possible, you need to light a scene and make that light simulate real world light very closely. This is what radiosity is for.

yes but... in photography a lot of artificial light is used (for interiors studio shots etc) - reflector panels, and things like this

true about the emitters reflecting in the tv - i could fix that for a final image, at the moment it doesnt bother me

This is only true if you're trying to reproduce a natural lighting setup. Even then it isn't true as radiosity is a mimic of how light works, but falls short. Hence the little helpers to make it "feel" right.

Cool.

Did you use the SLA shaders? I wisch you could share the c4d-file... :-)

A good work here, but just one question: why do not use the Area Light near the windows instead of the omni?

pegasus - its all bitmaps,

MrBraun - i have done many many many tests with area lights, omnis, emitters etc and i have found this tecnique to work best - the omni isnt actually anywhere near the windows though

here is twilights old scene where i used a similir technique to the one above

looking good and the images have a natural feel and depth. But what about the splotches?
How high are the rendertimes without splotches?
And did you use colormapping?

MrBraun

This is a test render with one Distant LIght and one area light with soft shadow into windows!

No post work ! ;)

well done sir. 30 minutes is impressive

thanks Sketch

Here's the file - try and optimize it and post your findings if you like

notice the soft omni in the room is in the exact position as the camera

I have seen the scene !

Wiht this technique have a good illumination but, the doors into back dont give illumination ?

With a spot light and the emitter (nothing sky), back haven't the light ! ;)

What do you think? ;)

Ric535
06-08-2005, 01:04 PM
i did try giving the back doors illumination but i didnt like the look - it looked to fake - see image, these doors arent actaully a window so wouldnt really create light in the scene

http://members.aol.com/rikwatkins/3D/Sala-Back.jpg

i think the sptlight in place of of the camera gives enough light on its own combined with emitters

Have you got the colour mapping plugin installed?

make sure the glass is hidden for the first radiosity pass also as that will dimnish the light otherwise

MrBraun

I see !!

I try new settings and post the result !! ;)

I prefer standard lights, like this:

C4D: R9.1
Radiosity: None
CPU: 3 GHz HT Intel Pentium 4

This is brilliant!

I'm going to see what kind of hash the translation sites make of this since I don't speak the language.

Well done.

Stain777, do you know of a Czech translator? If so, pls post. I want to read that article, too. Thanks.

The only Czech translator I could find made an hilarious mess of it. (something about a navel?) http://translation.langenberg.com/

But the tut page has pix and downloadable scenes, so it sorta makes sense even without a translation.

Looks good, but there ar estill a ton of splotches around the entire ceiling where it meets the walls.

Not this thread again!!!

Good work guys. I guess you will fall into the same conclusion we always do: C4D can't produce an artifact free GI interior. There's nothing wrong with your setup or method, it's a software handicap.
I'd wait for the next AR with my fingers crossed.

sorry the sofa belongs to twilight - i must replace it
You're free to use that sofa anywhere you want to, as well as the rest of the model.
I've seen people taking credit for the whole scene and that doesn't bother me...


Cheers!

I can get this scene pretty clean with upped samples as this was only a 30 min render, i dont think the GI solution is quite as nice as VRays though as i have had the chance to test it and all i can say is that in half a day of using max i was achieving the kind of results that have taken me months in cinema,

I really do think there will be an AR update this year, i have a fealing about it :)

About the sofa :thumbsup:

Thief?? NO NO. Something must have been lost in translation. I was actually paying you a compliment.

I would also like to re-state that I think your tutorials are very helpful, even if we can't understand the language.

OK :-), I am satisfed...

Thank you for your compliment and to english versions of my articles... I am looking for a english writer of my works. I have talked about it with Stain 777, but he is very busy (I am too :-)).
I can prepare english "command list", short descriptions and english screens (I have czech screens, of course). You (anybody) can prepare english text and after translation I can make pdf version of my article for Maxon. You will be sign like co-author, of course.

This'll be a good opportunity to get some of your great tutorials converted over. I finally found a Czech online translator and it was a miserable experience. I have a little more time this week so I will jump on the first one you provided me.

Just having english screens and commands would be a big help, since you so generously supply the scene files.
