Double plane glass (thin box) works fine in indigo, actually that's what I always do....

Hi Richard,
turning to the dark side ? (= using something else than maxwell) :wink:
What would be the problem with using dual layered glass with all normals pointed externally?

Mate I just remember the time blow out issue on the one (from the light side) with MR.

Plus all my windows are now single sided :evil:

Ouch, those surfaces will need a CTRL+'pushpull' and some normal checking.
Sketchup needs a good multiple pushpull tool to make this go fast.
btw, a single surface also works but i haven't tested the difference in appearance yet.

Sunlight in interiors problem

Post by ryo » Fri Mar 02, 2007 9:02 am

Okay, Chris...
first I thought you had forgotten to turn your model to have the north pointing upwards when looking to the plan. (I realised I had to turn my models in order to have north at 0° = up towards the Y axis, otherwise indigo doesn't respect the orientation of my sketchup model), but when you removed the glass the light entered the room, so it wasn't that...

second, don't forget to have a depth in the glass mesh, I use 1cm generally, and don't have any problem with sunlight thru windows.

Hi Ryo,
Good to see PPB is well represented by now here on the forum.
So you use double faced glazing... Do you set IOR 1.5 or keep it at 1.0 ('air')?

BTW very nice image. i would just brighten it a little. It looks noise free. What was the render time? Did you use my hint to set consec.rey at 50 and turn bipt. off?

regards,
biebel

Thanks Chris :)
glass is default glass, IOR 1.5 or 1.52 I don't remember...
the model is ... well... you know, Michel's Ando's House in Sumiyoshi.
the image is untouched, raw from indigo, default render settings, just rotated the model to have the sunlight entering the room and lickin' the wall...
7h render with my dual Xeon 2.8Ghz but 1 thread, 2Gb ram. but the image here is resized a bit (1280x960 originally), this perhaps explains the apparent noisefree-look.
what impressed me is that the glass creates a caustic line on the floor and the aluminium frame hit by the sunlight as well, without even having to tick a 'caustics on' option... and the fact that the exposure problem is relatively well solved: no washed area, and no dark black area neither. the image can thus easily be tweaked with PS to get a little more light in the shadowed areas, and place blooming glares here and there at will... :shock: :D

The thing is mate I have 33 diferent window components in the one design I'm working on so yep Ouch! I wished I'd made the glass plane a component itself! :(

Problem I'm having with Indigo is that I can adjust the aperture size to effect DOF but then I can adjust shutter speed to get more brightness. Its ok If I use a aperture size to create significant DOF but if I want most of my image in focus light is lost.

Ryo

Open your aperture to fix the light.

It seems that section of the Indigo forum could become a PPB members second residence...

PPB = PushPullBar
http://www.pushpullbar.com/
a forum focused on contemporary (but not only) architecture and design, initially gathering people using Sketchup as a tool of choice,... but now its expansion attracts the interest of people far beyond the sketchup community.

btw, Chris... I tried the Church of the Light (model by Mitch) but it's impossible to get sunlit interior... very strange... unless I switch off the glass layer... :?
I don't understand why?

Where i can i get the model of Ando's Sumiyoshi house?
Any chance you could send it to me?

I have found the model on the PPB forum you suggested but i cannot find the scene in the first image of this thread. Any help on this one.

Regards

Darren
