A textured glass-based article with multiple haze levels is provided. The textured glass-based articles are produced by utilizing a combination of etching and mechanical polishing to produce the multiple haze levels. 1. A method , comprising:{'sub': 1', 'a1', '1, 'texturing a surface of a glass-based substrate to produce a textured glass-based substrate having a first thickness t, a first surface roughness R, and a first haze H; and'}{'sub': 2', 'a2', '2, 'polishing a region of the surface of the textured glass-based substrate to produce a glass-based article with a surface comprising a polished region with a second thickness t, a second surface roughness R, and a second haze H,'}{'sub': a1', 'a2', '1', '2', '1', '2', '1', 'a1', '1, 'wherein R>R, H>H, t>t, and the glass-based article comprises a region having t, R, and H.'}2. The method of claim 1 , wherein the texturing removes from greater than or equal to 5 μm to less than or equal to 50 μm from the surface of the glass-based substrate.3. The method of claim 1 , wherein the texturing comprises etching the surface of the glass-based substrate with an etchant.4. The method of claim 1 , wherein the texturing comprises mechanically lapping the surface of the glass-based substrate.5. The method of claim 1 , wherein t−t≤2 μm.6. The method of claim 1 , wherein:{'sub': 'a1', 'Ris greater than or equal to 300 nm,'}{'sub': '1', 'His greater than or equal to 30% to less than or equal to 100%,'}{'sub': 'a2', 'Ris greater than or equal to 0.2 nm to less than or equal to 10 nm, and'}{'sub': '2', 'His less than or equal to 0.2%.'}7. The method of claim 1 , further comprising:{'sub': 3', 'a3', '3, 'polishing an additional region of the surface of the textured glass-based substrate to produce a glass-based article comprising an additional region with a third thickness t, a third surface roughness R, and a third haze H,'}{'sub': a1', 'a', 'a2', '1', '3', '2', '1', '3', '2, 'wherein R>R3>R, H>H>H, and t>t>t.'}8.
