Try different values. Sometimes it happens.

[menno (Menno Deij - van Rijswijk)]

Or in two steps: first QuadRemesh to get a quad mesh, then ToSubD to convert the obtained mesh to a SubD. I have the impression that QuadRemesh works, but afterwards it fails to create a SubD.

If there is a preview, and OK doesn’t give me anything, this looks buggy to me.

I agree, I’m typing up a YT atm

@menno

I have the impression that QuadRemesh works

I have the impression that QuadRemesh is ultrafast, 100% from the beginning on.
We have to wait for the remaining 0% for an unpredictable time.
The green progressbar is not very useful.

_QuadRemesh pretends to be super fast

[V8] _QuadRemesh has this nice green progressbar. It runs from 0% to 100% in no time. And then it takes a while to get the result. Not so informative. _ReduceMesh writes the progress in the command area. And doesn’t lie. The _QuadRemesh’s progressbar is unique, no other command shows such. I like the progress in the command area better.

There are some nasty mesh edges in your object in the lower end. I’d consider shrinkwrapping the result first to clean that up

[Charles]

@Gijs

shrinkwrapping the result first to clean that up

Works so far, thank you.
Having a preview and then no result is at least confusing.
