do you want to load 3d object using three.js https://threejs.org/
from .obj octet-stream?

I didn't try to load the files keeping on the wwroot. I kept them on the plugin directory as generally, we keep static files inside specific plugin projects and load them from there, so that extra files don't occupy any space while uninstalling that plugin. Thanks for the advice, I'll apply your trick.
Uploaded files under another domain first. Later used the directory URL as it wasn't working with the local directory.
