Try applying the texture *after* the transformation, see if that makes any
difference. I think because the slope map *depends* on surface angles, it
will not necessarily work the way you might expect before/after
transformation:

#declare Obj = box {
   <0, 0, 0>, <1, 1, 1>
   translate <-0.5, -0.5, -0.5>
}

#declare Tex =
   texture {
     ArMa_pBoxMap(<1, 1, 1>, array [6] {
       pigment {color rgb <1, 0, 0>}
       pigment {color rgb <0, 1, 0>}
       pigment {color rgb <0, 0, 1>}
       pigment {color rgb <1, 1, 0>}
       pigment {color rgb <1, 0, 1>}
       pigment {color rgb <0, 1, 1>}
     })
   }

union {
   object {Obj translate <-1.5, 0, 0> texture { Tex } }
   object {Obj rotate <0, 45, 0> texture { Tex } }
   object {Obj rotate <0, 90, 0> translate <1.5, 0, 0> texture { Tex } }
   translate <0, 0.5, 0>
}


.... The other problem could be that (iirc) sometimes the texture of the
first object in a union can override that of other objects, unless they
have their own individual textures defined. Either way the above code
should fix it.
