Works fine for me. You need just set for all cubes Pass Index 1 or more and for some cubes set the checkbox Depth Write, it’s unchecked on some of them.

At first you need to operate not to “.image-button.annotation_button” in your puzzle but only to “.image-button”. The second you set src file directly inside the gtml element but you need to set it as “background-image” in style of the object.

is it possible to load all the features ( like video window from url or website ) in that small opened pop up after mouse hover? Similar to what we do in case of old annotations?

Yes, it,s just a simple div element, you can put inside it all what you can put inside any div on the page, so it can be video, link and even iframe with another 3d configurator.

How do you try to change it? with puzzle or animation?

Just use hide\show puzzles, or uncheck eye icon for the object this will hide the object on export.

You can link materials into object not append them from library then on export they will rendered as one material, not duplicated. To assign new material on multimaterial object you will need to separate it on parts in blender so each part will have only one material. Unfortunately it’s the only way. If you append scenes into one scene from multiple GLTF files then better to have materials in main scene and append them on new appended objects to be sure they are not dublicated.
