please I need you help

Sorry, I don't know how to use this feature. I'm Korean, and the text explaining how it works is not detailed in English, so the interpreter is having a hard time using this feature. I tried to use Obsidian and lol2gltf, which I previously posted as an alternative to this feature, but everything went smoothly with this feature, but the skl and skn values of lol2gltf show that instead of the one material shown in the video, the body, eyes, tail, and big tail values are a total of 4 materials. And the reason why it's version 2.1 in the picture is because cli.exe is on for a while and then off again. Please help
