Hi Jark,
that's normal will happen in every other render software, too.
If you add a lot of objects, maybe with a big amount of polygons and maybe textured with big bitmaps the rendertime will increase or maybe the render will even collapse. But that's a question of memory.
So take care for not using to many objects with a high number of polygons. You can see number of polygons in the object inspector.
Cheers
Patrick

Hello Patrick,
Are you referring the scene information panel?, Do you know how many poligons max you could use per scene before begin to go slow?
Thanks

Hi Cobollero,
yes and no. Yes regarding the panel and no regarding max :-)
Only thing I know is that if you use some aof with lets say 700.000 polygons - like some high detailed models have - this starts to increase render time extremely.
That's why I most of the time use polygon cruncher before converting an object into aof.
Mostly it works reducing number of polygons around 50 % without loosing quality.
Cheers
Patrick

Hi Everybody,
Patrick,
What kind of software do you use as a "polygon cruncher"?
or what kind of method?
Thank you in advance
George

Hey guys, I want to get in this conversation. We are an architectural firm that utilizes Artlantis for quick and easy rendering. However lately we have been getting projects that are larger and larger. A hotel for example. The renderings are 3000 x 2100 pixels so that we can achieve a good size image at about 10" x 7". The rendering is set at High anti-aliasing and MEDIUM Radiosity. We have cars, trees, and a max of about 10 lights set to 250 power in the model and it is still taking 20 to 30 hours to render.
I know this seems about right to me, but for speed of delivery purposes just seems too slow. I use a MAC with 8 core processing power and it STILL takes this long.
Are there any neat tricks to speed up the large models?
Thanks guys.
Josh

Hi Josh,
would be interesting to know how many polygons this scenes have in total.
The size of your images do not sound very big for me. Usually I render something around 7000 x 4375 px and all settings to high.
Last project I rendered (see picture above) took 1 h and 24 minutes.
Maybe you can save much time by using billboards instead of 3d objects.
Cheers
Patrick

What a beautiful image! You're right, I need to look into how to use billboards. Do they create a rectilinear shadow though? I guess I don't know anything about them.
I'll post an image and show you what took so long. My guess is the trees. Do billboards create any realistic shadows?

Hi Josh,
yes a good made billboard creates a realistic looking shadow. Sadly it is not able to receive shadows.
I for myself use billboards where I need to see a shadow on ground or walls. Same with reflections in windows. In the picture above you can see some trees reflecting in the windows. These are billboards I placed outside the camera. I disabled the automatic for following the camera and set them parallel to the windows.
In the WIP section http://www.artlantis.com/apartments-in-germany_f-atl_wip-17863.html you can also see the original picture made by ATL without postwork.
I think only the ivy were 3d-objects. All other plants were billboards or placed in postwork. That's much faster and even more realistic than the best 3d-object.
Cheers
Patrick

Hi Patrick,
Thank you for your respond.
I look for the polygon cruncher.
The rendering time above is very itresting in that high resolution. May I ask about your computer and operating system?
Today I was keep getting during my work "not enough memory" (4 gig) on an Intel quad under Win7 64 bit.
Does more memory help on it or just wasting money?
cheers
George

Hi George,
I'm working on a Bullman mobile Workstation:
Bullman E-Class
intel core i7 980X 6 x 3,33 GHz
Windows 7 pro 64 bit
8 GB DDR3 ram
nVidia GTX 285 1 GB
ATL 3.0.3.2
A render like the one above I do in ATL 32 bit without problems. Before I used a DELL mobile Workstation and rendering a scene in a resolution like the one shown above always ended with crashes.
Since using this new Notebook batchrenderer never crashed again. I would use ATL 64 bit for bigger scenes but as far I as noticed it is not able to render billboards by now. For this reason I'm only using it for interior renders.
Maybe some parts of my system were a waste of money but I can't say which one :-))
If you look in the benchmark thread there was by now (as far as I remember) only one system faster than this Bullman mobile workstation.
Cheers
Patrick

Tons of great information. Thanks again!! I'll definitely check out the BB builder and start using that. I wanted to show you this image just so you know what I am talking about. This took 20 hours.
Can you believe that??!!!!

Only by watching this picture it's difficult to say where the problem is. Times like 20 hours I was used when I was using Vue.
But now I think there has to be a lot of information in a scene to make it render for hours. Check number of polygons in your scene. That's the easiest way to find out if this is the problem.
I found out that I have 3d trees causing 500.000 polygons for each tree. Place 10 of them you have a problem.
Next problem can be size of textures. If you use very large textures with high resolution this will increase rendertime, too.
Cheers
Patrick
PS. Nice looking building

It's a nice rendering, congratulation!
Are you using the neon shader for example? That could take lot of time. Other question: what is your accuracy setting? For this camera position I can easily imagine low anti-aliasing and normal accuracy.
Other question: are you using lot of reflective shaders?
20 hours for this image seams a bit too much for me too.

Firstly, thank you for the kind words, both of you.
I will check all these things. No neon shaders. No complex textures. At least to my knowledge, but I will check. My thoughts, after reviewing your helpful tips, are that the model was built TOO complex. The ground planes are archicad meshes which are probably millions of polygons. Combined with the Artlantis trees and cars. These are the most likely culprit.
Szabo, what do you mean by accuracy? Are you referring to the radiosity setting? The image was on High for everything which is probably another mistake.
20 hours is WAY too much. I'm just new.
Cheers for the help!!
I'll post a new image when I can finagle some time into the rendering.

Hi Patrick,
Thank you for the details of your computer.
It seems to me you have a monster!
6 cores? Whuhhhhhh That is what I call LAPTOP!

Hi George,
yes. That's a laptop or even better. Some kind of body building. This monster has almost something around 5 kg.
The word mobile gets a new sense.

One thing I forgot. Yesterday I converted this ceiling lamp shown in the picture above. There is only one light source inside.
The lamp has something around 106.000 polygons. That's not much. The same scene, decorated with some other ceiling lamp, was rendered in a size of 3000 x 1824 px, all settings to high, within 25 minutes.
With this lamp, the rendertime increased up to 1 h 20 min.
I think it's what Ildiko already said. The more reflective materials or the more calculations for light ATL must make, the longer the render will take.
In this case the light has to go through all these little glass balls around the lamp and these glass balls have almost 100.000 polygons, each placed in a different angle.
Subsuming I can only say reduce complexity of a scene as much as possible if you want to render fast.
Cheers
Patrick

I was mentioning the rendering parameters of accuracy, yes. There is a tutorial about the detailed features here:
http://www.artlantis.com/index.php?us=1&page=products/news_radiosity
Some tips: if you work in ArchiCAD, the export plug-in is able to transfer the AC layers on which there is 3D geometry. Setting the appropriate combination (visible and hidden layers) for a camera view, you can reduce the number of "active" polygons for a scene, which also may speed up the rendering.
An other idea is to organize the Artlatnis objects also on layers and hide those not visible for a view. These are small tips, but useful when it is about the time.

Jark -
Another thing to check is the distance of your model from the origin point. I had an extremely large and complex model that was taking around 20 hours to render. Low and behold, it was because of the models POSITION. Nothing more.
Take a look at this conversation.

Dear Josh,
- How long does it render without the cars?
- How long does it render with the cars but with restricted values for length of mirror on their shaders?
Greatings,
Riggie.
