Yes, in the usual case of applying an 'object pattern' pigment to an object,
that's true: The pattern is 3D and created at a specific place in 3D space from
the object it is given; then the object it's applied to (the surface of that
object) needs to line up more or less with the pattern in the same space, to see
*some* effect of it. Both things can be translated individually to get the best
line-up, AFAIK.

But I sense that BE's idea is to actually REPEAT the 'object pattern' (or *any*
pattern) on each and every triangle of a mesh via uv-mapping, even if the mesh
is some kind of complex rounded form. If so, it's an intriguing idea; I wonder
if it's possible.
