okay, i need your help guys, this is my first time importing to unreal
so, my model required more 2 uv channel,
the first channel is for the diffuse map (it has tiling texture, so i need to overlap some uv)
the second channel is for AO (this one is a non tiling texture, so i dont have any overlapping UV in order for AO to work)
my question is how to make AO in unreal to read channel 2 (my AO uv) instead of 1?
thanks in advance
