Thanks a lot! That's exactly what I need. Does POV-Ray take memory only
for one map in this case ?:

#local DomeMap = pigment{
 image_map{jpeg "cathedral/dome1.jpg" once}
 scale<1/4, 1/2, 1/4>
 translate y*0.5
 warp{spherical}
};

sphere {
   0, 1
   texture{
     pigment{DomeMap}
     rotate y*0
   }
   texture{
     pigment{DomeMap}
     rotate y*90
   }
   texture{
     pigment{DomeMap}
     rotate y*180
   }
   texture{
     pigment{DomeMap}
     rotate y*270
   }
}

Gena.
