   But there you are translating the isosurface function, not the texture
later applied to it: you need to translate it independently.

   BTW, after seeing at last the "problem object", I think it has an easy
solution, as long the base the texture is the same for all: just lay the
"global" texture at each sub-object:

union{
   object{board1
     texture{t_wood
       // local transforms here
     }
     texture{t_dirt}
   }
   object{board2
     texture{t_wood
       // local transforms here
     }
     texture{t_dirt}
   }
   ...
}
