When you open an existing project, you may see a warning about unknown components and a notification that no components are loaded.

I haven’t found a condition, but in rare cases, at some point the unknown components warning disappears and the components start loading properly.

In any case, it seems that the modules are not loading, so how do we handle this?

The current version of Needle Engine looks like this
Version 4.2.6(local) / NE 4.2.6 / NODE v20.9.0

Hi June.

The “unknown components” error typically occurs when the engine fails to recognize specific components associated with your objects. This often relates to missing dependencies not properly installed or components that are not defined in your current project environment.

Here are a few steps you can take to resolve this issue:

  1. Check Dependencies: Ensure all required npm packages are installed correctly. An npmdef might need to be created to define any missing dependencies. The warning you see may also suggest that you forgot to install one of these packages (see the documentation).

  2. Re-install Packages: Sometimes, simply re-running the install command can solve hidden issues. You can delete node_modules and run a clean installation:

    rm -rf node_modules
npm install

  3. Verify Component Availability: Check if all the components you are using in your Blender/Unity project are available in the current version of the Needle Engine. It’s possible components were removed or renamed in updates.

  4. Use Debugging: In your engine setup, enable logging for missing components. This will notify you of any unknown components as they are processed in real-time (see the documentation) (see the documentation).

  5. Confirm File Paths: Ensure that the paths to any asset references are correct within your project files. Missing assets can lead to components being marked as unknown.

  6. Update Needle Engine: Sometimes, updating to the latest version of Needle Engine can resolve compatibility issues. Ensure you are running compatible versions across your dependencies (see the documentation) (see releases).

If these steps do not resolve your issues, please provide additional details about your project setup, and let’s explore the problem further.

Hi @hojun

The dynamically imported modules error is an indicator that a module was loaded to the running dev server that wasn’t being used before (e.g. when you change from the sandbox sample to postprocessing). If it happens try to restart your local dev server (there’s a terminal/commandline window that you can close and then just click play again in Unity).

It might already fix the other warnings too so please try this first, if not I would need a bit more information about your scene and scripts
