I have a union of *many* copies of a heightmap.

Except the pigment, the texture (normals and finish) of each element is 
identical. It's a random color for each instance.

If I assign pigments individually and assing normal and finish to the 
union, will I save memory?

Thanks,

Fernando

What is a heightmap?

No.

Sorry! It's late and I'm tired! I tried to say height_field.

So, it's the same to apply the whole texture individually or to the union?

Thanks,

Fernando

Probably most memoy will be taken by height_field itself. You might want to 
convert it into mesh.

Btw, perhaps it is a good idea to add to POV-Ray support for referenced 
objects (not only meshes) so that 

#declare thingy = object { ........ }

even if object tooks 1 MB of memory, then

object { thingy }
object { thingy translate ... }
object { thingy translate ... }
object { thingy translate ... }

will took like 1.01 MB of memory, not 4 MB.
