Sory, an hollow object DOES have a depth. The purpose of hollow is to allow an object
to CONTAIN or 
be filled by a media or fog.
map_type 2 is cylindrical maping, the image is applied to the cylinder and don't
replicate on the 
far side of it, but will apears on the inside part of the difference of 2 cylinders.
To prevent that, you should apply it only to the exterior part, the large cylinder,
not to the whole 
difference.
