The new version of ArcGIS Urban (July 2021) introduces a simplified and more consistent interface for data exchange using the new ArcGIS Urban API (https://developers.arcgis.com/arcgis-urban-api/). This was necessary to allow seamless integration of ArcGIS Urban into a broader range of applications. Please note that due to this automatic data exchange between CityEngine 2021.0 and ArcGIS Urban is temporarily unsupported for plans and projects that have been upgraded in ArcGIS Urban. Those items will not be displayed in the ArcGIS Urban tab of the CE Navigator anymore. Bildschirmfoto 2021-07-22 um 17.39.56.png CityEngine 2021.0 users that need to sync their upgraded ArcGIS Urban projects and plans are encouraged to reach out to support or ask workflow-specific questions on ArcGIS CityEngine Questions.

Hello @Muhammad_ShahzadZafar When looking at your provided Collada (.dae) 3d Model, I noticed that most geometries have a redundant material assigned. This might have happened unintentionally during the modelling process. ThomasFuchs_1-1623160698112.png A simple insert rule can remove the undesired materials: version "2021.0" @File attr assetPath = "DAE/Part1/Part1.dae" attr removeMaterial = ["__auto_1","__auto_","__auto_4"] R--> i(assetPath, yUp, keepSizeAlignPosition) comp(m){all: RemoveMat } RemoveMat --> case findFirst( removeMaterial , material.name) > -1: NIL else: print(material.name) X. This lets you then get the textured buildings in CityEngine: ThomasFuchs_0-1623160630578.png

@DevinLavigne yes, from within CGA, it is not possible to set a style. Styles can only be selected in the CE Inspector.

Hi Devin Thanks for your input. We are investigating the issue, since the files in the project are not changed by opening or closing a project. Thanks Thomas Fuchs

Hello @JulieGrindborg To me it really looks like the project was not properly removed from the workspace. It would be best to create a new workspace and link the project again. Thanks Thomas Fuchs

Hello @romainjanil and @DevinLavigne Thanks for your input. With python it is indeed only possible to set attributes, but no styles. The CE team is looking into this. Thanks Thomas Fuchs

Hello @DidemDidem Thank you for your Error report. There has been some updates to the Python component in the last release. To track down the issue, please provide some additional information: Which version of CityEngie are you using? Does this happen always you open the console? Have you tired to create a new workspace? Thank you Thomas Fuchs

Hello Rihab Bouallagui‌ Usually, the "unknown texture" texture appears, when the asset is not readable or doesn't exist in the CityEngine workspace. Please check all assets paths in your rule file, if they exist and can be previewed (Right Mouse Menu > File Preview) e.g.: texture("/ESRI.lib/assets/Facades/International/Groundfloors/g_f001_t001_Mercantile_001.jpg")‍ These CGA operations set texture assets: texture operation—ArcGIS CityEngine Resources | Documentation material.map shape attribute—ArcGIS CityEngine Resources | Documentation

I can confirm that there has been a change on the server-side, that prevents the get map data search to receive results. The necessary changes were made for the upcoming CityEngine 2020.1 version. Please excuse the inconvenience.

Hello Ufuk Deniz ÖZTÜRK‌ Thank you very much for your report! Currently I can't reproduce the issue with CE 2019.1. Maybe the connection to Python is blocked by a security setting? What also would be very interesting to know, if the problem persists with CE 2020.0 . This version is using a new version of the Python development framework. It could be that issue was fixed by the upgrade.

Hi, Thanks for your questions. In general one should use unique project names to avoid naming conflicts. When using (cloud) archiving it's recommend to export a project to an archive file. Note, in case the export is too slow, you can uncheck "Compresses the contents" (resources selected to be exported) in the archive that is created. Once the project is exported, it can be removed from the workspace and disk. Export a project—ArcGIS CityEngine Resources | Documentation In case import is prevented with the warning: "Some projects cannot be imported because they already exist in the workspace", the existing project in the workspace needs to be renamed/removed.

Symptoms and Affected Systems: We experienced rendering issues causing (amongst others) artefacts in the viewport no labels in model hierarchy transparent textures missing or being fully opaque The issues seem to be related to certain newer AMD graphics cards like the Radeon RX 5XXX series and platform specific drivers. Affected systems include late 2019 MacBook Pro 16-inch models. If you experience problems like the issues above try the following workaround (needs CityEngine 2020.0 or newer): Workaround: Make sure the latest graphics driver is installed. If rendering issues are still present, continue with step 2. Open the configurations file CityEngine.ini (requires admin privileges) Windows: Open the C:\Program Files\ArcGIS\CityEngine2020.0\CityEngine.ini in a text editor. Mac: In the Finder, Right Click on the CityEngine2020.0 application > Show Package Contents then navigate to Contents > MacOS > CityEngine.ini and open in a text editor. Enforce blending transparent content, by adding the following line to the CityEngine.ini file: -DforceSimpleTransparency=true‍‍‍‍‍‍ Start the CityEngine application

Hi Derrik, in 3D rendering the phenomenon creating those fuzzy surfaces is called Z-fighting. It occurs when two or more primitives have very similar distances to the camera. This would cause them to have near-similar or identical values in the z-buffer, which keeps track of depth. This then means that when a specific pixel is being rendered, it is nearly random which one of the two primitives gets drawn in that pixel because the z-buffer cannot distinguish precisely which one is farther from the other. To avoid this from happening in your CGA code, it is important to add NIL to the leaf shapes that are not needed to be drawn. e.g.: Generate --> Paint Report Paint --> color("#FF0000") Report --> report("facadearea", geometry.area()) NIL‍‍‍‍‍‍‍

Hi Martin Chapple‌ please go to the download page again using a different browser (e.g. Chrome or Firefox). Most important: Esure JavaScript is enabled. https://www.esri.com/en-us/arcgis/products/esri-cityengine/trial Choosing an industry in the dropdown menu should then be possible.

Hello Valentina Welcome to CityEngine To get elevation data with your map you need to have an Organizational ArcGIS Online account. You can start a trial from here: Free 21-Day Trial of ArcGIS Online | Esri
