Question Multiple glb importers. How do I fix this?

I have two packages that each have their own glb and gltf importers (MRTK3 and Ready Player Me). This give me two errors like the one below. How do I fix this? I seem to need both importers. If I remove one, the package that uses that importer doesn't load the assets it needs properly and ultimately doesn't work.


Multiple scripted importers are targeting the extension 'glb' and have all been rejected: Siccity.GLTFUtility.GLBImporter (assembly: C:\Users\Chris\Documents\Unity Projects\MRTK3SetupTest\MRTK3TestSetup\MRTK3TestSetup\MRTKDevTemplate\Library\ScriptAssemblies\Siccity.GLTFUtility.Editor.dll), GLTFast.Editor.GltfImporter (assembly: C:\Users\Chris\Documents\Unity Projects\MRTK3SetupTest\MRTK3TestSetup\MRTK3TestSetup\MRTKDevTemplate\Library\ScriptAssemblies\glTFastEditor.dll)
UnityEditor.AssetImporters.ScriptedImporter:RegisterScriptedImporters ()

 

This is working. You are a lifesaver! Thank you sir.

 

Hi Both,

I seem to be facing the same issue with ReadyPlayerMe and the TriLib package (https://assetstore.unity.com/packages/tools/modeling/trilib-2-model-loading-package-157548) .

This is the error:

Multiple scripted importers are targeting the extension 'gltf' and have all been rejected: Siccity.GLTFUtility.GLTFImporter (assembly: D:\Users\Tony\Desktop\XRLab\ARSandbox\Library\ScriptAssemblies\Siccity.GLTFUtility.Editor.dll), TriLibCore.Editor.TriLibGLTFScriptedImporter (assembly: D:\Users\Tony\Desktop\XRLab\ARSandbox\Library\ScriptAssemblies\Assembly-CSharp-Editor.dll)

Multiple scripted importers are targeting the extension 'glb' and have all been rejected: Siccity.GLTFUtility.GLBImporter (assembly: D:\Users\Tony\Desktop\XRLab\ARSandbox\Library\ScriptAssemblies\Siccity.GLTFUtility.Editor.dll), TriLibCore.Editor.TriLibGLTFScriptedImporter (assembly: D:\Users\Tony\Desktop\XRLab\ARSandbox\Library\ScriptAssemblies\Assembly-CSharp-Editor.dll)


Just wondering if these a was a permanent fix that is not base on the user selecting on drop down. Couldn't I have each package using a different importer?

 

I was able to solve this issue by making the ReadyPlayerMe importer optional as shown above. Then whenever I import a ReadyPlayerMe object I select the Siccity importer. I wasn't able to access the importer code for MRTK3 since it's built into a DLL. It got rid of the error and worked for me.

 

Hi, but where is the script to modify as reported above?

 

Greetings,

I'm facing a similar issue. I'm using a package for .webp handling. However, I don't want to use their default importer but use my own custom importer.
Can I make my importer the default one?
I could edit the one from the package, but as Unity guidelines for git are to ignore the Library it would fail for every other user that works with this project and I don't really like to have everyone do it manually on every setup.

Edit:
Changing the annoation of my custom importer to:

Code (CSharp):

1. [ScriptedImporter(1, "webp", -1)]

resulted in the desired effect.

 

what's the solution if you can't edit ScriptedImporter?

 

I was able to do this with Siccity/GLTFUtility and MRTK 2.

I first had GLTFUtility in my project, without the MRTK.

In the GitHub repository for GLTFUtility, I searched "ScriptedImporter" and found it in GLTFImporter.cs and GLBImporter.cs. From there, I went into both of those scripts in Unity. Here's what it looks like for GLTFImporter.cs.



You can see that I commented out everything but the line with

null

in the ScriptedImporter attribute. I did the same thing for GLBImporter.cs.

After doing this, an issue with my GLTF model showed up. Still, I stayed the course. I deleted my model for now.

I installed the MRTK 2 via the Mixed Reality Feature Tool, and then reimported my model. Finally, I clicked my model and there was the dropdown to select the importer.



I wanted to use GLTFUtility, and was able to select it. After that, my model was working fine again!
