Thank you for reporting the issue. The CityEngine team has fixed it in the upcoming 2018.0 release. As a workaround for 2017.1, add this line to the CityEngine.ini file: -DsnapshotFsaaLevel=0 On Windows, the file is located in the installation root folder. typically: "C:\Program Files\Esri\CityEngine2017.1\CityEngine.ini" On MacOS it located is inside the application package. First you need to open the application bundle: Applications > CityEnigine > Show package contents Second you browse to the file: Contents > MacOS > CityEngine.ini ... View more

Hi Nate, Thank you for this question. The CGA street rules work on CityEngine dynamic shapes and their attributes. By changing the underlying graph properties, the shapes are automatically regenerated. Here is a Python script to accomplish this task: ''' Created on Apr 23, 2018 @author: ESRI R&D Center Zurich ''' from scripting import * # get a CityEngine instance ce = CE() def findDeadEnds(nodes):     deadEnds = []     for node in nodes:         if ce.getAttribute(node,'valency') == 1.0:             deadEnds.append(node)     return deadEnds      if __name__ == '__main__':         # get selected nodes     nodes = ce.getObjectsFrom(ce.selection(), ce.isGraphNode)     # get all dead end nodes     deadEnds = findDeadEnds(nodes)         # set all dead ends to 'Roundabout'     ce.setAttribute(deadEnds, '/ce/crossing/type', 'Roundabout')     ce.setAttributeSource(deadEnds, '/ce/crossing/type', 'USER')         pass‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Hi Kenneth, thank you for your question. Below is a small example how to use two object attributes to set a layer attribute: attr StreetType  = getObjectAttr("type",false) attr bikeLanes  =      case getObjectAttr("bikeLanes",false) > 0 : rint(getObjectAttr("bikeLanes",false))      else : 0 attr streetWidth =      case StreetType == "MAJOR" : 24 + 1.5*bikeLanes      case StreetType == "MINOR" : 13 + 1.5*bikeLanes      case StreetType == "LOCAL" : 5.7 + 1.5*bikeLanes      else : 10‍‍‍‍‍‍‍‍‍‍ Further information and examples can be found in the CityEngine Help Mapping Object Attributes via Layer Attribute  ...

Hi Luiz Thank you for your input. I changed the script in my post above to add export support for 360 panoramas from CityEngine View Domes. For View Domes it now creates six 90° x 90° square snapshots (back, down, front, left, right, up). These can be stitched and re-projected from cubemap to equirectangular format with common VR/panorama tools.
