Blender export babylon plugin export alpha material question

load gltf model file:

export to babylon format model file:

My question is why there is a perspective between transparent objects when I switch to Babylon format.

What parameters do I need to adjust for this plugin?

The transparency dropdown. In your picture, the value looks like a bunch of Asian characters. Checking the published source, it is right there. Think I cannot help you other than 2 double check the .zip file corruption.
