Like say I have a metal fence with these 2 identical bars, one below the other going across and I UV unwrap the top one, would there be any way to copy that UV layout to the bottom one? Or should I just delete some pieces and use one in an array modifier setup?
Script > UV copy from active may work. Otherwise just duplicate the top bar, as it’s already uv mapped.
Okay, cheers for the advice
you could unwrap the second object and set it over the other UV map
