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.
