Hello Javad Salimi Thank you for your question. You can use the Python script below to align selected floor shapes of a building to a terrain. First specify the ce.alignShapes() parameters as documented here​: Align function Heightmap Offset from scripting import * # get a CityEngine instance ce = CE() # align shapes parameters alignFunction = AlignShapesSettings.TRANSLATE_TO_MIN heightmapName = 'Terrain_Satellite' groundOffset = 0.0 # selected floor shapes floors = ce.getObjectsFrom(ce.selection()) # get initial heights initialFloorHeight = [] for f in floors:     vertices = ce.getVertices(f)     initialFloorHeight.append(min(vertices[1::3])) initialGroundFloorHeight = min(initialFloorHeight) # align floor shapes to ground settings = AlignShapesSettings() settings.setHeightmap(heightmapName) settings.setAlignFunction(alignFunction) for i in xrange(0,len(floors)):     settings.setOffset(groundOffset + initialFloorHeight - initialGroundFloorHeight)     ce.alignShapes(floors, settings) ...

Hello Stefano, Thanks for the post. Your report has been forwarded to the admins of the download site. There are also other customers reporting the same issue. I'll update this threat when the issue is resolved. ... View more

Black polygons can also be caused by wrong faces normals. Have you checked that the normals are set correct? Select a black polygon face and try Shapes > Reverse Normals. This operation reverses the normals (i.e., the orientation) of all selected faces. This step is often necessary after importing shapes with reversed orientation. ... View more

Hello Reit Sined One hour to open CityEngine is extravagant, indeed. When starting CityEngine the last scene is opened automatically. May I ask, which part of opening takes so long? Is there any progress bar or status message? Which version of CityEngine are you using? Does the startup time change, when opening an empty scene and restarting CityEngine? In case it is a certain scene that takes so long to load, is there anything special about it? Is there a particularly big street network? Your feedback on this matter is very much appreciated. ...

Hello Jugal, Thank you for the report. So far, I have never seen reports of such an artifact pattern. There seems to be an issue with textures rendered black in certain areas. Does this happen all the time, or only occasionally? Does it help to change the panorama image? (Edit > Edit Panorama > Environment Map) What is your graphic card driver version? What are your settings for the Procedural Runtime? (Edit > Preferences > General > Procedural Runtime) ... View more

Hello Renato, Thank you for your reply. This threat provides a way of doing a simple flyover animation with CityEngine. But CityEngine is not intended to be a standalone solution for animation. I am sorry, if you got the impression this would be the case. Instead, the development team is working closely with key customers in the VFX industry to meet their production needs. Today CityEngine provides a wide range of 3D model export formats, and there are continuous efforts to support the latest standards. This includes support for animation software workflows like: Autodesk 3DS MAX and Maya: Autodesk FBX Export Pixar Renderman: Renderman RIB Export ... and others ... View more

Hello Marta, One reason could be, that you are using the BASIC version of CityEngine. Python scripting is only included in the ADVANCED version. Please refer CityEngine the feature list: Esri CityEngine | Features ... View more

Hi Dave The "Generate Bridges" option sets the height depended on the attribute 'height' (if present). This is mainly thought to be used with 2D data that has some segments (like bridges) with height information. Maybe this is the cause of your strange results? ... View more

Hello Scott, I think it would worth trying a newer version of CityEngine like 2015.2 first and check if the problem is sill present. ... View more

Hello Thomas, you can use the CityEngine Python Scripting Interface to automatically export to small patches of your scene. The code example below creates 4 patches and should be a good starting point: def checkInside(shape,xMin,xMax,zMin,zMax):     vert = ce.getVertices(shape)     for i in xrange(2,len(vert),3):         if (xMin <= vert[i-2] <= xMax) & (zMin <= vert <= zMax):             return True     return False def exportPatch(shapes,xMin,xMax,zMin,zMax):     exportSettings = FBXExportModelSettings()     exportSettings.setBaseName("fbx_batchexport_"+str(xMin)+"_"+str(zMin))     exportShapes = []     for shape in shapes:         if checkInside(shape,xMin,xMax,zMin,zMax):             exportShapes.extend([shape])     if len(exportShapes):         ce.export(exportShapes, exportSettings)         def iterate():     shapes = ce.getObjectsFrom(ce.scene(),ce.isShape)     patchSize = 256     xMin = 0     xMax = 512     zMin = 0     zMax = 512     for x in xrange(xMin,xMax,patchSize):         for z in xrange(zMin,zMax,patchSize):             exportPatch(shapes,x,x+patchSize,z,z+patchSize) ...

Hi Tobias, I'm sorry, but there is no way to open a CGA rule file generated by the facade wizard in the facade wizard again. The CGA file alone does not contain all the information needed. Please immediately review and correct the CGA after export while the facade wizard is still open. ... View more

Hello Scott, Thank you for your report. Can you please give more detail on the version of CityEngine and the coordinate system you used for your scene? Exporting a street network as multipatch should be no different to a export of any other geometry. For graph networks there is also the option to export it to FGDB as a plolyline. ... View more
