Dropping .dds files into browser issue

OK folks.

Something is happening that is not expected.
I’m using the Maya exporter which runs my exported gltf in chrome browser…fine!
But then I drop a .dds file onto the browser to load the environment but instead of loading it in, it downloads it to my downloads folder.

Any idea as to why?
Sorry guys but Im still earning…

Hey are you using sandbox.babylonjs.com to test your scene? (Only palce where we support DDS drag’n’dropping)
