hi Tim, I tried, but sadly, I cannot reproduce the issue. can you make a quick step by step list with a new scene & simple rule which let's me reproduce the issue ? let me know .. ... View more

hi Kevin ! this is odd .. are you located in the US ? if so, please contact esri support (support@esri.com) and ask them for a Time Limited Full License / TRIAL extension, mentioning your issue. if you are located outside the US, please find your local Esri Distributor and contact them, with the same inquiry. http://www.esri.com/about-esri/locations.html you'll get access to the full installer (which has the Exporter also included) plus an Activation Code. ok ? ...

hi Dan ! 1] do you have the same issues if you deactivate Ambient Occlusion (save scene /restart may be needed.) ? 2] can you send a more complete log ? 3] how much RAM do you have ? 64 bit OS ? 4] If you can not fix the issue with point 1] or upcoming hints, maybe we'll need to get the project .. ...

hi ! thanks for the inputs. one very important point : from what I see in your pdf and the other comments, what you are trying to achieve is to basically reverse-engineer building shells realworld facades from existing oblique imagery and other sources. this is NOT something which you can do with the CityEngine. At least at the current state. The CityEngine is a so-called 'procedural modeling application' which creates 3d buildings based on input shapes plus a rule set. The process you describe goes rather in the direction of photogrammetry. reverse-engineering building volumes and facade pattern analysis is something we may offer in future, but is not ready currently. if you're interested speficifally in this, I'd recommend data providers as http://www.cybercity3d.com/ , which you then of course can also use in CityEngine as imported 'static models'. What I'd recommend is that you look at the 'Philadelphia Example' which shows how you can work with geolocated models derived from photogrammetry (kml files) and the CityEngine's procedural modeling functionalities. let me know if this cleared the maze a little .. 🙂 ...

hey there ! this could indeed be an issue with the scene coordinate system. Can you check the code whether the UV projection of the color texture contains 'world' ? Something like : setupProjection(0, world.xz, 586, 442) lemme kno-hooow. 🙂 ... View more

hi ! glad this got you further. there are a few possible issues here. - if your 'object' is an inserted asset, then you would want to translate BEFORE a comp(f) because the object then is still 1 mesh. after a comp(f), you get n objects. - depending on the each shape's normal and scope, using a translate may move the shapes in different directions, which you may want or may avoid. if you just want to move vertically up, you could also just add a 'alignScopeToAxes(y)'. best is you play a little with a simple cube, a comp(f), the 'alignScopeTo' and (maybe) also the reverseNormals operations to drive the direction of any translations. ...

hi ! does the '.obj' format also crash UDK ? if you just create some very simple geometry, does it crash too ? ... View more

hi Matthew ! thanks for the kind words ! the CityEngine currently still is missing some important features, such as e.g. dedicated ways to visualize e.g. sewer networks. I guess, with some 'hacks', it would be possible to visualize such datasets. just a few days ago, we received a similar inquiry and got a small dataset in the form of .stm (storm water file format) which I opened up in a Civil3D trial version. I've seen such inquiries also some time ago while we still were Procedural, but now, under the ESRI flag, we'll have much more capacities in working on solutions for e.g. pipe networks. since most of us here are programmers/developers (and me being an architect), we have only very limited knowledge of the specific needs for those tasks, so it would be REALLY helpful if you could provide me with a list of functionalities you would need. I have seen that sewer similar networks are basically polylines with attributes like diameters, material, position, .. can you provide more insight ? you could e.g. post the wish also under the CityEngine ideas : https://c.na1.visual.force.com/apex/ideaList?c=09a300000004xET&category=Esri+CityEngine please let me know ! kind greetings ! ...

hi ! the TRIAL version is not limited in those functionalities. since the CityEngine project is set up in project folder structure, you need to first place your files you want to work with in the CityEngine project. things you want to use must be placed in those folders to work with them, thus we named those folders as a default. directly linking files from ArcGIS is not yet possible, thus you need to work with e.g. picture files or 3d assets. please note also that it's best to work with picture files smaller around 4096x4096 pixels due to the fact that CityEngine handles textures in memory and not as a 'service' as e.g. ArcMap which enables unlimited data (e.g. tiled 10 GB GeoTifs). Thus, if you want to visualize large datasets, you'll need to use the CityEngine as content creation tool and bring the final buildings to e.g. ArcScene, which were created based on a 'down-resed' terrain model. DEMs, TINs and GRID-based terrains are not yet supported, thus you need to work with raster-based terrains such as 32 bit tif files. Here's some resources : http://resources.arcgis.com/content/cityengine/about --> check Gallery ! ... View more

hi Anna, yes, you can do this and for example, we're doing this in the classification if you import osm files. select the layer into which the street segments are imported, then in the Inspector, you can go grab the Object Attributes which came in with the SHP file. an example : class = getObjectAttr("class") attr streetWidth = case class == "highway":   true else:   false an example like this would make it possible to select all graph segments which have the attribute "class" with the value highway ( which is true ) the selection itself is then done in the viewport by RMB-->select by Map Layer. play with this a little, ok ? let me know how it goes ! ...
