separate UV channel in unreal. need help

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 :slight_smile:

You just need to plug a Texture Coordinate node into the UV input for the AO texture in the material. You’ll have to change the UV channel on the textures coordinate node.
