I was not able to reproduce this.

Can you specify the version of CloudCompare you are using, as well as the original and destination file format(s)?

And maybe share the cloud with us maybe?

The MLS treeted file blows up over 2gb so sprend wont work. I set a radius of 0.1 in MLS and the finished file has NULL as boundingbox.

Cloudcompare is from 24 June

So on my side, with the cloud you provided, I see that what happens is that some spurious points are created very far from the original cloud: image

So I guess that instead of an absence of bounding box, it's more maybe an infinite or at least very large bounding box?

And this algorithm is imported 'as is' from PCL... I'm not even sure to know how it works 😅

Strange, have it been updated on another side?

I opened an issue on PCL on Github.

Feel free to add context as in PCL version and stuff

Ah yes, we probably haven't updated to this version... We'll try to do it (hoping there haven't been too many changes that would impact the existing codebase 😅 )
