"Unsupported filetype selected" when exporting scenes to Carla

I create a simple scene in RoadRunner, see in the attached picture, and when I want to export it to carla, I found that I can't check "Split by Segmentation". And when I type in the File name "try" and click "save", there will be a "Unsupported filetype selected Please save as a supported file type" error. Can someone help?

By the way, when I try the "OpenDrive Export Preview Tool", when I click "Export", it failed with some error, see in attached. How can I fix it?

Can someone help? I have figure out the filename issue and it can export now. However, I still cannot check "Split by Segmentation", and still have the "ERROR: Failed to fetch 'xxx': Asset file is missing" issue.

Hi. I have the same two problems as you, how did you solve them? Especially the first one: "Unsupported filetype selected"

The message "Failed to fetch '<PROJECT>..." is due to an entry in the project's OpenDriveAssetData.xml file which references an asset which is not in the project.

The OpenDriveAssetData.xml file can be found by navigating to the Project folder of the RoadRunner project and can be edited in any text editor.

There will likely be an entry for each error printed that looks something like this:

<Object>
    <Ignore>true</Ignore>
    <FilePath>Damage/Cracks01.rrpms</FilePath>
</Object>

Removing the entries containing a <FilePath> not in the project should clear the error messages

Further documentation on the OpenDriveAssetData.xml file can be found here: Convert Asset Data between RoadRunner and ASAM OpenDRIVE - MATLAB & Simulink (mathworks.com)

Thank you very much, it helps a lot. BTW, how about the problem about checking the "Split by Segmentation" I mentioned above? Is there something wrong in my ceation of the map?

Split by segmentation is always enabled when exporting to Carla. The checkbox is disabled since this is the required value.

If you would like to disable "Split by Segmentation" on export, the recommended way is to either export an additional Filmbox file to replace it, or set up your own custom Carla configuration and set the desired options: Export Custom Formats - MATLAB & Simulink (mathworks.com)
