Hey guys. I just wanted to know if any of you would know something about this. Do you guys know of any good city generators that can render a city?
thanks

"cityengine" is nice and they offer a trial version. its a tool to generate the city...it has no abilities to render them nicely. you need another program to do that.

very strong

also ArcGis

I've not used ArcGIS, but can confirm that CityEngine is pretty awesome, Rockstar use it to generate the GTA cities.

The tricky bit is getting a heightmap of the area from outerra, into cityengine...

I had seen CityEngine when it was developped by a Swiss company years ago; then ESRI bought them
How much does one advanced license cost ?
How is LOD managed with their datas ?

I myself answer to the above question about LODs. 
They do that inside their appli, in coding with attribut and case statements...

It's about $4k a user XD
It uses a scripting language to determine how the building models are generated, so you can also pretty easily have it generate LOD models at the same time.

Most of the rulesets that come with the tool have 2 lods. I export these to Maya and set my render szene up there usually. (I have a license from office that has the fbx exporter). U can also link in your own objs and have them scattered. City engine does lots of things right. It could be a good blueprint for something similar in outerra

I guess if we are talking about procedural city generation, it's obligatory to link the Subversion demo XD

Thanks for sharing these infos.
How many levels of detail can OT deal with so far?
I remember having read somewhere about 6 levels for imported models (importer thread?) - is it still true ?

So if you want to provide 6 LODs for real-time rendering in OT (if we forget an eventual procedural capability for model gen...)
it means that the process should be :
- model in CityEngine or in any other modeller
- then export the datas (meshes and textures) to FBX or another format
- import these in a tool able to work on the LODs
- then re-export for OT

I must admit that I don't know how LODs are practically managed in tools like 3Ds, Maya and others, so my questions...

I think it is actually more like 14 LOD levels.. But nothing is using that now.

14 levels
