I has made bucket render image before and want to add smart object on my label. Since this model perspective doesn't same like can or bottle where it has pure cylinder shape, i cant use cylinder warp there.
the solution that i can think for now is just use custom warp with 4x4 grid, where it will be pain in *** if i do it manually since there is no mirror system while moving the warp point.
and this is my example that i want to apply on my label.
I has saw the same thing on graphicriver mock up and someone was doing it well.
