I just want to confirm something. If I leave any texture, as non advanced, that mipmaps are not enabled.
I just want to save myself sometime as oppose to going thru each texture, setting it to advance then disabling mipmaps.
I believe that MipMaps are enabled by default: if you disable it in Advanced mode, the slider to see the actual MipMaps gets disabled, yet it is enabled in Texture mode.
However since Unity 3.5 you can select multiple textures, change them to Advanced and disable MipMaps at once!
