Hello. If you look at the block from an angle, the texture looks very blurry. I'm using "Azapz UltraReal x256" texture pack.

MCPE-45927 , MCPE-21930 - Similar problem, "num_mip_levels": 0 (and 2) in resource_pack_name/textures/terrain_texture.json didn't help.

This is strange, but I changed "num_mip_levels" in my add-on and the textures blur is gone.
