Hi @DJ_GIS, It appears that the issue is related to incompatible Datasmith versions. CityEngine 2024.1 exports in a newer Datasmith format that cannot be imported into Unreal 4.27 without errors. Unfortunately, there isn't an easy workaround for this problem. I recommend trying the export with the suggested CityEngine version 2021.1. Best, Benjamin

The easiest way would be to already set the correct value in CGA, this would create all material instances with the correct value. Otherwise a slightly faster approach directly in Unreal would be to open the Parent Material, delete the connection to the roughness value in the material and connect a constant value node with the desired value. Another approach would be to use Editor Utility Widgets https://docs.unrealengine.com/5.3/en-US/scripting-the-unreal-editor-using-blueprints/ to adjust all the materials via blueprint scripting, but it would probably take some time to get started with this approach.

Hi, The easiest way to add reflections to your scene is to decrease the roughness value on your building materials (I got similar results to the screenshot when I set them between 0.05-0.1). This can either be done in Unreal https://docs.unrealengine.com/4.27/en-US/Resources/ContentExamples/MaterialNodes/1_4/ or already in CGA https://doc.arcgis.com/en/cityengine/latest/cga/cga-material-attribute.htm Improving the reflections can be done in multiple ways, I would suggest to look at the following website https://docs.unrealengine.com/5.3/en-US/reflections-environment-in-unreal-engine/ Best, Benjamin

Hi Karl The .sln file is not needed to open the project, if Visual Studio is installed correctly you should be able to open the project by double clicking the CEVRExperience.uproject file. As described above, if the dialog about the missing modules pops up, you need to click Yes. In case you still want to create the .sln file, right click the .uproject file and select "Generate Visual Studio project files".
