Sorry to bump an old thread, especially since I found a duplicate thread of this in the expressions section that I already bumped, but I have run into this issue as well.
I would love to know if there is a workaround, or if there is an alternate plugin I can buy that wouldn’t stair-step the aliasing so bad at the higher heights/widths of the sine wave. My anti-aliasing setting in the wave warp plugin is set to high, but it does no good (layer quality is also set to high).
None of my research has pointed me in the direction of a third-party plugin that works the same way. But perhaps someone knows of one available.
