STL Loader file path issues

Questions

Hi everyone,

I have some problems rendering my STL file with the STLLoader from ThreeJS.
First, I encountered this error message RangeError: Invalid typed array length: 16367289120.
I imagine it’s because I didn’t give the right path from my file to the loader.
My STL file is in the same directory as my script file (src directory), so I just put the name of the file as the url path like so :
stlLoader.load(‘orthese.stl’, function (geometry) {}
I don’t know which path to give to the loader.
Thanks.

Are you using the latest version of STLLoader from the three.js repository?

I did install three.js with npm. I’m actually using the v^0.119.1 from three.js, I don’t know if it’s good or not, let me know if not.

Are you hosting your application on a web server? Please make sure with the browser’s dev tools that the STL asset is actually loaded from your backend.

Here is my project repository : https://github.com/NeroAdvents/threejs-tutorial.git
Feel free to look at the App.js file where I’m using Three.js.
Also, I’m using ReactJS.

Loading the STL file produces this response:

      It will be replaced with the URL of the `public` folder during the build.
      Only files inside the `public` folder can be referenced from the HTML.

      Unlike "/favicon.ico" or "favicon.ico", "/favicon.ico" will
      work correctly both with client-side routing and a non-root public URL.
      Learn how to configure a non-root public URL by running `npm run build`.

So there is something wrong with your react app configuration. This issue is unrelated to three.js.

Yeah, I finally managed to load the model. I guess it wasn’t able to access my src folder because it was private. I put the model inside the public folder and it works fine now.
Thanks for the help !
