When I'm trying to create Anti-XRay textures, it fails for reason noticed in the title. X-ray for entities works through manipulation with materials (entity.material, terrain.material). So I created a resource pack that will contain same files from vanilla pack so that they replace the X-ray texture. But it's not. Order of textures is right. I'm not really sure is that a bug or an expected behaviour, but I really need help with this. Thanks in advance.

Here both X-ray and Anti X-ray textures, and screenshot of their order.
