It’s a bit hard to find in its current implementation. The Sculpt Mode’s Remesh section doesn’t contain it, it’s hidden in the Remesh section of the Object Data Properties tab.
It would be nice to have QuadriFlow as an option in the Remesh modifier.
QuadriFlow is very slow at the moment. When I set the amount of faces to only 20000, it takes more than 20 seconds to remesh a non-complex model on my reasonably powerful system. That’s not usable for frequent remeshing in Sculpt Mode, and QuadriFlow’s results are not good enough for final auto-retopology.
It’s got its issues, such as this deviation after a QuadriFlow remesh:
In the above screenshot you can also see that the distribution of triangles inside the quad faces is quite unorderly, which becomes apparent in Sculpt Mode.
A symmetry option is much needed, and should speed up the process as well.
I haven’t noticed a significant difference between activating and deactivating the ‘Use Mesh Curvature’ option. What’s the best scenario to use it?
It seems not multi-threaded at all, I do hope it gets improved a lot in future versions same with the Voxel Remesher and Dyntopo, these three are now a killer combo.
I’m in the middle of testing Quadriflow on a prety heavy mesh - 6,5mil poly. It’s taking over 2 hours and the progress bar is on 50%. The lack of multithreading is very bad on performance side.
Also it’s using all of 128GB RAM + additional 90GB of swap.
I’ve done tests with voxel remesher and sharp option in remesh modifier with the same model. Comparing to Quadriflow they are lightning fast.
If the Quadriflow can produce better quality mesh I can understand it’s usage in edge cases, but I can’t see it as a reliable every day tool in its current shape.
Whoa, seriously? … What’s your target polycount?
But yeah, quadriflow is very slow if you compare it with zremesher.
Also, sometimes is better to decimate the high poly mesh first, before running quadriflow/zremesher, it usually helps speed things up… and if your model is symmetric, always make sure the option to use symmetry is enabled in the remesher settings…
Target was going from 6,5 to 3 milion. The mesh is asymetric, and made in Dyntopo so there wasn’t much to optimise before.
Two hours wasnt enough. I let it do its job overnight. The mesh looks pretty decent.
If you’ve got some budget to spend, you can buy Quad Remesher for Blender. It’s significantly better and faster than Quadriflow, and offers more options to influence the result.
