Error at startup

[MiPa12]

Hi,
I try to set up your plugin. I got this error when I run the unreal simulation:
Error at startup: Unable to open file F:/vhacd/header.txt.
I haven't found the folder vhacd. I have only found this one: C:\Users\Administrator\UrdfSim\Examples\UrdfBot\LunabotParts\vhacd_bucket\header.txt.
I have changed the paths in settings-lunabot.json file and LunabotFromMesh.xml. Should I change paths somewhere else?
best, Michael

That error message is probably coming from the static mesh generator. It probably means that you are trying to read in a mesh in "manual" mode, but haven't actually generated the mesh yet.

The doc you want is this one. Most likely, you will need to change from "manual" to "VHACD" mesh generation somewhere in your URDF file.

I'm using the example URDF: LunabotFromMesh.xml. I'm not sure where I should change this. Can you explain shortly how to set up the lunabot example correctly. I copied the generated Plugin folder from UrdfSim in my unreal project folder. Pasted the content from settings-lunabot.json in the settings.json file. Changed the paths in the settings.json file to the location of the LunabotFromMesh.xml. Furthermore, I changed the paths from LunabotFromMesh.xml to the location of the STL files. I tested it with Visual Studio 2017. Switchted the Game Mode to AirSimGameMode. My uproject file looks like that: {
"FileVersion": 3,
"EngineAssociation": "4.24",
"Category": "Samples",
"Description": "",
"Modules": [
{
"Name": "UrdfSimTest",
"Type": "Runtime",
"LoadingPhase": "Default",
"AdditionalDependencies": [
"AirSim"
]
}
],
"TargetPlatforms": [
"MacNoEditor",
"WindowsNoEditor"
],
"Plugins": [
{
"Name": "AirSim",
"Enabled": true
}
]
}

Is there something wrong or missing? any tip will be appreciated, thank you

Can you show your full LunabotMesh? It's likely that the problem is there.

I have the same error. Do you have any solution for this?
