When I import a prefab and it says failed to load script and am not able to export materials or change anything in unity. Which script should I add here to get rid of this error

Hello Yazhini,

The issue you’re encountering with prefab imports and scripts failing to load can often happen if the scripts aren’t properly linked or if the prefab is using components that aren’t recognized or compiled correctly.

To address the error regarding “failed to load script” when importing a prefab, you may need to check the following:

  1. Ensure Script is Compiled: Make sure that the script you are trying to use in your prefab is correctly set up in the project and has no compilation errors. You can check for errors in the Unity Console.

  2. Correct Script References: If the prefab references a script that has been renamed or moved, it will lead to this error. Ensure that the script path and name match in the prefab.

  3. Export Settings: When exporting objects, ensure you’re using glTF-compatible materials and shaders to avoid issues with material properties not showing up.

  4. Add Required Typescript Components: Since the Needle Engine uses TypeScript for components, you must make sure that the corresponding TypeScript files are correctly linked to the Unity project. It might be necessary to add or regenerate components if there are changes in the TypeScript setup.

  5. Enable Debugging: Using debug logs can be helpful to see if the component is being loaded correctly and what might cause issues.

You should also consider looking into the documentation for proper integration of scripts and checking if any known issues exist regarding the script loading errors you’re facing.

Since you’re using Unity and may have specific dependencies, it would help if you could share the “Project Info” that can be copied through the menu item “Copy Project Info Into Clipboard.” This will allow for more targeted troubleshooting.

If you have any further specifics regarding scripts or setup, feel free to share them!

Hi Yazhini,

If you’re facing issues even after re-importing the Needle Engine package, you may need to ensure that you are using the correct default scripts and configurations that Needle Engine provides.

  1. Default Behaviour Script: The default script that is typically required to be linked with your prefab or gameObject in Needle Engine is NeedleToolsBehaviour. Ensure this script is part of your GameObject.

  2. Check Needle Engine Components: Make sure all necessary components provided by the Needle package are properly added. For instance, if using WebXR, ensure you’re including components like WebXR and other related components depending on your use case.

  3. Regenerate Required Files: After importing the package, ensure that you regenerate any necessary configuration files or scripts that may have been modified or are missing.

  4. Unity Console Errors: Review the Unity Console for any specific error messages or warnings. They often provide clues as to which components or scripts are missing.

  5. Unity and Package Version Compatibility: Confirm that your Unity version is compatible with the version of the Needle Engine package you have imported.

If the problem persists, please share the specific error messages from Unity Console or any additional details about your project setup that might help in identifying the issue further.

Please check the Unity Editor console log for errors or warnings.

This looks like there’s an issue with your file or an compiler error in Unity - but I need more information to be able to help.

File import is not done by Needle Engine but Unity.
It’s also not clear what file type you’Re importing here.
Please also share which Unity version you currently use.
