Transparent background and x axis only mouse

Hi!

First of all, thanks for your plugin and threes.js integration with WordPress.

I’m trying to reproduce something similar like this website:
https://jbalvin.com/

But I have 2 issues…

First one is that I need a transparent background to 3D view in order to blend with my website animated background (like in the example website).
I know glb file supports transparency but I can’t use .glb file with your plugin while threes.js supports it. So how can I remove background or make it transparent?

If needed to test previous example website is using this 3D file:
https://jbalvin.com/models/balvin/balvin.glb

Second problem is that to move the object I want to disable Y-Mouse Axis and use X-Mouse Axis instead like in the example website: you can move the 3D object by pressing left click and moving to the left and right but not moving up and down. It seems that by default this WordPress plugin does the opposite (can’t move left and right but only up and down).

Please let me know how to solve these issues ??
