Nvidia has announced that it will be transitioning Omniverse to a dedicated Developer SDK and is stopping development of connectors effective October 1st, 2025. In response to this change, Esri will also be retiring the Omniverse Connector integration in ArcGIS CityEngine. ArcGIS CityEngine 2024.1 is the final release to support the Omniverse Connector (version 1.0.6). The Connector will no longer be available for download after October 1, 2025. While the connector is being deprecated, the built-in USD exporter of ArcGIS CityEngine provides an alternative workflow to export city models to Omniverse. This is done by manually uploading your exported USD files to the Omniverse Nucleus server. This approach provides similar results to the connector, though without automated network transfer and live sync capabilities: Use the CityEngine "Universal Scene Description (USD)" exporter to write the desired scene to USD files. Use the Content Browser of an Omniverse-Kit Application (e.g. Composer) to open or upload the files to an Omniverse Nucleus server. Additionally, we will also retire "Serlio", the CityEngine plugin for Autodesk Maya at the same date. Release 2.3.0 for CityEngine 2023.1 is the final release. Serlio was originally developed for the M&E sector to help ingesting complex procedural building models into asset management systems. With the advent of USD (Universal Scene Description), this workflow is now considered obsolete. We recommend users of the "Serlio" plugin to consider an USD based workflow: Use the CityEngine "Universal Scene Description (USD)" exporter to write the desired models to USD files. Use the Autodesk MayaUSD plugin to import the files into Autodesk Maya. We will keep the corresponding github repository in read-only mode for future reference.

Hi, connector version 1.0.4 only supports up to CityEngine 2023.1. I've submitted connector 1.0.5 for CityEngine 2024.0 to Nvidia a few days ago and it should appear in the launcher anytime now. Thanks for your patience & best, Simon

Thanks for reporting this! Just to be sure I understand correctly: you manually fixed the Tr (or Tf?) value in the mtl files? Or did you set opacity in CGA? Would you posting a diff of a "good" and "bad" mtl for your use case? Best, Simon

Hi Francisco, from your screenshot, I think Puma tries to construct a building on each triangle passed in from Rhino. In version 1.1 we added some tools to control how the Rhino geometry is passed to Puma. You basically have three options: Treat the input shape as "multi-polygon" and use the CGA cleanupGeometry operation to remove internal edges in the rules. Use the Rhino commands AddNgonsToMesh and DeleteMeshNgons to control how polygons are grouped together into Ngons within the mesh. Use the "Ngon" plugin for detailed control of the conversion. In options 2 and 3, Puma will recognize the Ngons created by above methods in the input meshes and use them to create the actual input polygon faces for the model generation. Please see the first link to the Puma manual for details. Hope this helps & kind regards, Simon

Hi, in your rule snippet, "model" is not defined and neither "model1" nor "model2" are used in an "insert" statement to actually read the assets. Try to add this rule: model --> i(model1) Hope this helps & best, Simon

Hi Ahmed, one starting point could be the "multi modal lanes" rules in the "Complete Streets" example (see Help Menu -> Download Tutorials and Examples). The main tool to use is the UV split operation. Hope this helps, Simon

You should have access to CityEngine 2022.1 in your MyEsri account. If you do not see 2022.1, feel free to send me your Esri customer number in a direct message so I can forward this to our customer service. The viewer included in 2022.1 is fully self-contained, i.e. you should be able to extract it and put it on a web server. Please note that this is not anymore a supported product, i.e. there might be functional limitations as well as security issues. Best, Simon

Hi Marie, The current recommendation is to export and publish SLPKs (Scene Layer Packages) to ArcGIS Online (or Portal) and then view them in ArcGIS Scene Viewer. These formats are fundamentally different and you would need to re-export your CityEngine scene. AFAIK, there is currently no Scene Viewer based app with the same functionality. Our apologies. In version up to 2022.1 you can use the "offline" viewer for this. The below command will open a browser window using a locally served copy of the 3ws viewer: Best, Simon
