How fix GLTF Lib Error?

Library\PackageCache\org.khronos.unitygltf\Runtime\Scripts\SceneImporter\ImporterTextures.cs(252,24): error CS1503: Argument 2: cannot convert from ‘System.ReadOnlySpan’ to ‘byte

It looks like you’re encountering a compile-time error related to the GLTF library in your Unity project using Needle Engine. The error message indicates an issue with argument types at line 252 of the ImporterTextures.cs script in the org.khronos.unitygltf package.

To help resolve this, here are a few steps you can take:

  1. Check for Updates: Ensure that both Needle Engine and the org.khronos.unitygltf package are up to date. Sometimes, such errors are fixed in newer versions of the packages.

  2. Modify Importer Scripts: If the update doesn’t resolve the issue, consider modifying the ImporterTextures.cs script around line 252. The error suggests there might be a type mismatch between ReadOnlySpan and byte[]. You could try casting or converting the ReadOnlySpan to a byte[].

  3. Seek Community Help: Since you mentioned this is from the Needle Engine forum, seek help there with additional context. Providing the exact code snippet around line 252 would be very helpful.

  4. Consult Documentation: Review the documentation for both Needle Engine and the org.khronos.unitygltf package for any updates or known issues related to GLTF importation.

If you provide the relevant code snippet or more details, I can assist further with specific changes or workarounds.

Hi, please share your Unity version and Needle Engine package version and UnityGLTF version. Thank you

Please update Unity (current version is 6000.0.68). The version you currently have installed also has a security issue that Unity has fixed.
