If you apply a texture to a union of several copies of a mesh, and the texture
is  duplicated on each mesh, rather than "flowing" across them, comment out the
uv_mapping keyword in the mesh code.

This is probably bleedin' obvious to some, but I managed to waste a couple of
hours on it last night.

  Well, if you are using uv-coordinates, then it means that you are saying
for each vertex, where the texture should be got from. Since you are copying
the mesh, then of course these uv-coordinates are the same for each mesh.
