Question about Texture MipMap x Texture Arrays x Procedural Meshes

So, I would like to understand better how mipmap works together with texture arrays and procedural meshes, does the MipMaps works automatically when inside a Texture Array? Does they work when used in Procedural Meshes? And with both?

When I try to debug it with the Required Texture Resolution is shows the mesh with the texture array as “undefined”

So, it seems like it works, even though all texture had MipMap generated, I have disabled the MipMap
(Mip Gen Settings was set to NoMipmaps) in the Texture Array by mistake, making it never be used.
