Material: using texture bombing to remove tilling

Hello,

I was wondering if this will remove the tilling in any good way

I was able to make a PBR material, with a parameter that change the offset of the texture, problem, it don’t show up the change on the terrain, even it show the change in material editor

If i change any of other parameters, it will show on the material instance AND on the terrain, everything work exept the offset parameter
