I tried it, and now I remember what I forgot: I had already tried, and this is
why it won't do for me:

It is inside the same index of a texture_list. and POV tells me it is "expecting
} ...other texture found instead" POV won't accept layered textures inside
texture_lists.

We use those in Blender exporter to convert several materials per object. The
rest of the texture translation code is already quite convoluted to be able to
use transparency maps, along with diffuse color map, bump map and specular map
using several finishes mixed together.

any other workaround?
