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.

Sadly it doesn’t help when you have several models with the same textures: unreal changes UV channels in each differently, so when index works in one it doesn’t in other .__.
