different texture scales

Ahoy mates,
I just need to know before I start with my project, if I have to copy a texture, if I want to place one onto various entities with different texture-scale and flags.
That seems to need quite a lot of memory, but I can't find any other oportunity.

Cheers mates

If you actually load the objects which reference the same texture only one texture will be used in memory. Therefore you can adjust the scale in your modelling package per object.

or

If you actually want to change the scale of the texture but do not want to waste texture memory, scale the UV mapping coordinates instead.
