URDF Importer causing WebGL build errors in Unity #201

Open kyle-rr opened 2 years ago

kyle-rr commented 2 years ago

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.

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?
