Depot - The question was HOW, not IF IS POSSIBLE.
It's possible in single player, but i don't see a way to replace this in MTA.
@Critical Gaming:
I just got an idea, tried it already?:
txd = engineLoadTXD ("data/elegy.txd")
txd1 = engineLoadTXD ("data/elegy2.txd")
engineImportTXD(txd, 562)
engineImportTXD(txd1, 562)
probably will fail, but why not try?
