Did a first little test of QRemeshify versus Quad Remesher…

I tested it a bit yesterday and was pleasantly surprised. These were mostly clothing models. On items with medium mesh density, especially on items with holes, QRemeshify gave an even better result than Quad Remesher in the same amount of time. But on items with complex folds that bend and penetrate inside themselves, QRemeshify lost a lot in ditalization. The problem can be fixed by disabling the Preprocess option, but the rendering time increased by 22 times. At the same time, QRemeshify gave a more uniform and clean result. There is a difficulty with understanding the settings. Cool, thanks to the author for the work.

Nice tests, thanks for sharing. Your images mention Quad Remesher. Did you use that, or QuadriFlow? Looking at the result, I guess Quad Remesher?
Typo, thanks, corrected on Quad Remesher)

Up to now, QRemeshify seems to work best on organic meshes, not hard-surface meshes, but I’ll do some more tests.
Since that addon use ‘QuadWild with Bi-MDF solver’, which is a fork of ‘QuadWild’, it should be totally capable to manage hard-surface meshes, as shown here

Cool! Is it open source? Would be nice if we got a better baseline remesher in Blender for those not willing to fork out the cash for QuadRemesher, even though I still think it’s well worth the money.

There’s still a few brushes that are “hidden” behind the invert option of other brushes (or behind those “Invert to…” checkboxes, which were a horrible idea). Like Contrast hidden in the Flatten Brush, or Peaks and Deepen hidden in Scrape and Fill. Peaks and Deepen feel like inverts of each other more than Scrape or Fill, but there’s no way to make a Peaks/Deepen brush.
The problem is you can’t access them without holding the Ctrl key, so they can’t be their own brushes. I hope somewhere down the line brushes get separated into their base parts, so then we can assemble new brushes from them. Like define what a brush does when shift/ctrl/alt is held.

I think they can still be made into new brushes. On brush if you switch Direction and save it, then it will work that way without having to hold Ctrl. It was a bad design but shouldn’t matter anymore with brush assets.
That looks great indeed. Maybe I’ve just used a very unfit mesh for the algorithm in my first test. 
Looking at the Github page, I think it’s open source.

Nice! I hope we get it implemented into Blender in that case!

Although the instructions say that the edge guide flow is with edges marked with seams/sharp. It didn’t affect anything for me. I suspect that the guide function and tracking of the sharp corner are broken in this implementation.

Yeah, I guess so too. I also tried sharp edges as a guide, to no result.
Following my previous hard-surface tests with the QRemeshify auto-retopology add-on, there’s a new version now, which has fixed an issue where edges marked as sharp were not being detected.
QRemeshify now gives a better result, while the Quad Remesher add-on failed if I activated its hard edges option, so the edges are undesirably smoothed in that result.

Something’s happening!

Looks promising… but why the name of several blender addons ends with “fy”? 
C’mon, I mean, c’mon…

I guess all auto-retopology names were already taken…
- Quad Remesher
- Quadrify
- Quadriflow
- Instant Meshes
- ZRemesher
- AutoRemesher
- Autopo
- …
The next add-on will probably be called “Autoretopoquadpolymesherify”.

Btw integrating this remesher in Blender was proposed and we discussed in modeling module meeting, but unfortunately (IIRC) it uses way too many dependencies that are difficult to get into Blender for various reasons (some legal too I think) and even if they were all resolved platform maintainers were not happy with having to depend on that many external libraries (not having direct control, can’t fix things if they break easily, etc).
