Berlin courtyard (abduction/recycling)

Post by BbB » Wed Jan 09, 2008 9:14 pm

Hi all,
Here are a few things that have been cooking overnight at BBB Towers.
I wanted to take a break from glossy interiors and go to the opposite end of the cleanliness spectrum.
This scene is relatively low-poly, as you can tell from the close-up of the car. The displaced ground accounts for about 300 ,000 of the total 500,000 polys. I did most of the textures from photos of an actual Berlin courtyard I took last weekend. The textures for the ground, trees and car are from, reworked in PShop. The mapping of the building on the left could have been better. I noticed the problems only after rendering though...
I'll be posting a night version tonight. It's looking good but it's taking a hell of a lot longer to clear. I'm also thinking of doing a foggy one...

Greatfull BbB, again very very good renders :o

+2 for realism and details

you never sleep? Every two days you've got new finished renders (you've got a wife, incredible :lol:)

I love the last one, car texture and ground are so realistic.

Is it a real photo of a street and are you going to do other point of view?

Holy shit that's amazing ! You've got to show us the wireframe. Did you use one single texture for the wall on the left ?
It's impossible to notice it's low-poly. In fact at first sight I found the first image was your reference photo !
Apart from those technical remarks, that scene has an incredible mood.
... stunning !

Cheers mates. Very glad you like it.

No problem. I'll upload the wireframe when I'm back from work. Yes, each building has one texture map, built from six different photos. Given the resolution of the photos, I could have built a 60m-pixel map for each facade. But that sent Photoshop crashing and I'm not sure if Indigo would have handled such large maps. So I ended up having to halve the resolution. That's why the wall looks so blurry and pixellated in the close-up.
It's a pretty bad scene for close-ups anyway, also because of the low-poly models.

The street was the biggest challenge. I had a very hard time finding a tarmac texture big and detailed enough to cover so much ground. So I took a shot on CGTextures, made it tileable, and built a map four times as large by tiling it four times in one image. I then used the clone tool to introduce variations and break the tiling. That left me with a large-enough seamless road texture - but still not large enough for convincing close-ups (hence the DOF blurriness in the last image, which is here to hide the low level of details.
The next challenge was to make the water and create variations between wet and dry tarmac. The water is a plane covering the whole area and placed just underneath the road. After subdividing the road mesh, I used the sculpt tool to create areas of depression, revealing the water underneath. Then I took a screengrab in Blender in top view and imported that in Photoshop. There, I superimposed it over my road texture and painted a mask, covering in black the areas I wanted to leave dry. I used this B&W image a weight map to blend two road mats - a diffuse, dry one and a phong wet one, which I also made slightly darker.
(And since you're asking - no, I don't sleep much ;-). As for my wife, she's travelling right now and will be back next week, which is when my image productivity is going to take a serious hit!)

:lol: :lol: :lol:

Thanks for these details, I have a street to model near the school I show in "work in progress", will try to do something simple I think, not enough time... will post preview now

other point of view?

BBB, there are no words, really..
nor words or emoticons, i should say..

My best compliments, my friend!

So, given that now we're friends ( :wink: ) i dare to ask you something huge: i see you're a demi-god (no hyperboles, i swear) in setting materials and lighting. Would it be too much for you to make up a specific tutorial based on one of your images (let's say this one) to let us know yourmodeling procedure, your lighting settings and your excellent work on materials?
It would be of great help for anyone here who wants to learn :roll: ...

Obviously, this wouldn't have any restriction: you could do your tut anytime you've a little spare time and you're willing to..

Think about it and let us know!! :D

PS. This should be another poll request:

Yes, I fully intend to milk this scene as much as I can. I'll do other POVs in addition to the night version that's cooking right now. I also had in mind to do some not entirely realistic scenarios. We'll see if that works.

Thanks guys, much appreciated.

Cheers (though I do detect a hint of hyperbole ;-)
Happy to make a tut about the various aspects of this image, if you bear with me for a few days. What do you guys think would be the best way? A pdf? Do you know of any free software to make them?

Great work BbB! I'd like to see a wireframe to know what you modeled and what you bumpmapped. Sorry I don't know any free pdf converters.
