Problems creating a standalone executable

[marlonroda]

Hi,

We are experiencing some problems when creating the executable of our project (SofaUnity v25.12). One important characteristic of our project is that we are using your custom CollisionAlgorithm plugin.

We tested to create a project and load the NeedleInsertion example of the CollisionAlgorithm, it runs well in the game mode. When we publish the build and try to run it, we get some errors such this one:

Filename: C:/build/output/unity/unity/Runtime/Export/Debug/Debug.bindings.cs Line: 213)

Component: 'VisualStyle' under node: 'VisualStyle - VisualStyle' not reconnected to a SOFA component. GameObject will be removed.
UnityEngine.Debug:ExtractStackTraceNoAlloc (byte*,int,string)
UnityEngine.StackTraceUtility:ExtractStackTrace () (at C:/build/output/unity/unity/Runtime/Export/Scripting/StackTrace.cs:35)
UnityEngine.DebugLogHandler:Internal_Log (UnityEngine.LogType,UnityEngine.LogOption,string,UnityEngine.Object)
UnityEngine.DebugLogHandler:LogFormat (UnityEngine.LogType,UnityEngine.Object,string,object[]) (at C:/build/output/unity/unity/Runtime/Export/Logging/DebugLogHandler.cs:9)
UnityEngine.Logger:Log (UnityEngine.LogType,object) (at C:/build/output/unity/unity/Runtime/Export/Logging/Logger.cs:60)
UnityEngine.Debug:LogWarning (object) (at C:/build/output/unity/unity/Runtime/Export/Debug/Debug.bindings.cs:213)

Has anyone faced a similar issue? I searched for similar issues in the forum but there was nothing related.

Thanks!

Hello, InfinyTech3D dev here.

So, if I understand correctly, you are working with a SofaUnity v25.12 release that already includes the DLLs, and you also have a clone of this repository in your project:
[CollisionAlgorithm repository]
My first guess is that Unity did not include all the required resources during the build process.

Could you check if the CollisionAlgorithm folder exists inside:

YourBuildFolder/YourBuildFolder_Data/

If the folder is present, then check deeper inside it and verify that:

• the Sofa scene.py file is there
• all resources used by this Sofa scene are also included

If the folder is missing, try copying the CollisionAlgorithm folder manually from your Unity project into the _Data folder of the build.

You should preserve the same hierarchy as in your Unity project (basically treating the ..._Data folder as equivalent to your project's Assets folder).

You can also check if the SofaUnity folder was correctly included in the build by doing the same verification process.
The most important thing is to make sure the DLLs are present in: "_Data/SofaUnity/Core/Plugins/Native/x64/..." or in "_Data/Plugins/x.../"

Let me know if that fixes the issue or not, and we can investigate further if needed.

Hi Pierre, we are using the SofaUnity v25.12 release but we are using the DLLs from our local SOFA build instead of the ones included in the integration.
The folder CollisionAlgorithm does snot exist in MyBuildFolder\MyBuildFolder_Data\. I also dont understand what CollisionAlgorithm folder you are referring to.
I checked and the folder MyBuildFolder\MyBuildFolder_Data\Plugins\x86_64 includes DLL files.
The folder MyBuildFolder\MyBuildFolder_Dataa\SofaUnity\Core\Plugins\Native\x64 just included the sofa.ini file, I then copied my x64 of my SofaUnity integration and that also did not work.

Sorry for our late reply, we have been trying to make it work but so far its not possible.

Could you explain exactly how you install the SofaUnity v25.12, was it using the asset package?
You should first download the last asset release : https://github.com/InfinyTech3D/SofaUnity/releases/tag/SofaUnity_v25.12.00-URP

This asset include the SOFA v25.12 release and our plugin to use SOFA in Unity.
If you have you own plugin, make sure to build them using the SOFA v25.12 otherwise the dll won't be compatible with the Core of SOFA.
then you should add in your compilation the https://github.com/InfinyTech3D/CollisionAlgorithm/releases/tag/v25.12.00 to use it in SofaUnity

Let us know if it helps
Best regards

Hi Erik, thanks for your reply!

We are importing the release version of SofaUnity v25.12 from march 20. We imported that package but we replaced all the dependencies of the x64 folder with those from our SOFA v25.12 (built from src), even the SofaPython3 and its site-packages because we were having problems with dependencies (the release depends on python3.13). Additionally we compiled the 2 plugins from your company required for the needle insertion task: CollisionAlgorithm and ConstraintGeometry.

So a first thing to point out is that creating an empty unity project and importing the SofaUnity v25.12 released package does not work for us, we must replace those files I mentioned.

We are able to run our .py scenes inside unity, even those with the custom collision pipeline with a viscoelastic constitutive law. At some point we had to create an empty License folder in the path-to-our-project/Assets/SofaUnity so it can detect it was the free version, otherwise it would not work.

We were focused on improving a lot the visuals of our project and we are very pleased with the results. Now, i will try again the creation of the .exe, maybe try to catch any bug from our side.

Please let me come back with a detailed reply on the status of our executable.

Best Regards
