URDF Importer causing WebGL build errors in Unity #201

I'm using URDF importer tool to import my ROS env into unity. The import is successful. I could also simulate the environment and everything looks to be working fine. However when I try building the unity project for WebGL I get build errors. Looks like these errors are related to URDF Importer. When I remove the URDF importer from the package manager, the build succeeds with no errors, but I may need to use the URDF Importer at runtime later as I add more features to the project. (This bug is essentially the same as the one reported in #122, except my build is targeting WebGL.)

Here's the console output

 Packages/com.unity.robotics.urdf-importer/Runtime/UnityMeshImporter/Plugins/AssimpNet/Native/win/x86/assimp.dll would be copied to <PluginPath>/assimp.dll
 Packages/com.unity.robotics.urdf-importer/Runtime/UnityMeshImporter/Plugins/AssimpNet/Native/win/x86_64/assimp.dll would be copied to <PluginPath>/assimp.dll
Please fix plugin settings and try again.

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Here's my build options.

Have you fix this error?

Hi, we are running into the same issue. We simply load a basic URDF in Unity and try to build it for WebGL. The build fails with the following errors:

Plugin 'assimp.dll' is used from several locations:
 Packages/com.unity.robotics.urdf-importer/Runtime/UnityMeshImporter/Plugins/AssimpNet/Native/win/x86_64/assimp.dll would be copied to <PluginPath>/assimp.dll
 Packages/com.unity.robotics.urdf-importer/Runtime/UnityMeshImporter/Plugins/AssimpNet/Native/win/x86/assimp.dll would be copied to <PluginPath>/assimp.dll
Please fix plugin settings and try again.

Is there any alternate way to build robot models for WebGL on Unity?

Exclude AssimpNet/win DLLs from WebGL builds
1e94b32 
In the same project, we use URDF-Importer in Unitye Editor, but we also have scenes
that are built for WebGL.

As noted in Unity-Technologies#201
WebGL builds of a project that has URDF-Importer package always fail, even if
URDF-Importer is not used during runtime.

This commit marks the conflicting plugins to exclude WebGL.
NOTE: URDF-Importer scripts will not be usable in WebGL builds: Runtime/Unity.Robotics.URDFImporter.asmdef
still excludes WebGL. This change allows scenes that don't use URDF-Importer to build.
