Quad Remesher is an add-on for Blender by the same developer who gave the 3D sculpting community ZRemesher, UV Master and Decimation Master.

It's a paid add-on, with the option to either buy a lifetime license or buy a 3-month subscription. Well worth it in my opinion, at least if you’re a professional 3D artist looking to save some time.

Works for both organic and hard-surface models, although I think for organic models it’s more of a “one click” solution, and for hard surface objects it takes a little more planning, and isn’t always succesful.

Besides the above modeling course, I also made a Hard Surface Sculpting course, as well as a course about making drag and drop materials, like in Substance Painter, for use with mech models (though it also applies to other materials), no UV unwrapping needed.

To get all 3 courses + my 2000-page Blender Secrets book and accompanying videos with 60 dollar discount, you can buy them all as a bundle. The Complete Hard Suface Bundle.
