You messed up the first material – swordglow – instead of loading the texture for the glow, you load the texture of an angel with a sword.

I fixed it.

It looks strange, but the idea is that it was taken from the game, so the transparency should work fine there.

Hmm, the problem came from where I didn't expect it. I thought it was impossible, because I've been digging around in Characters for a long time and I understand their animations a little bit.
But nevertheless, if you write the path to another model for the artifact... it stops rotating, EVEN though the animation set hasn't changed.
I'm really shocked!)))
It's clear that Russian-speaking people created the file system (an error in the word "artifacts").
