@witch-dev , hi i don’t know how to use Github so i’ve downloaded as .ZIP your project anyway… i put back in github GitHub - LucianoJacomeli/RandomTiledRHAO in my version i add the RHAO version, my packed textures is: albedo, normal, mask = Roughness, Height, AO. Please test and check if is correct i think i’ve destroyed some parts, because my colors look strange. I only not understand why we need to put the mask texture weightmap in all texture.
