Yeah, same problem here. The looseness in the Surface Sampler node was working fine until 5.5, but now it’s seems relatively broken, or at least it doesn’t work at all like previously : Before 5.6, we could use a looseness value of any value above 1.0 and it would keep “spreading” points further from one another, but now it’s clamped to 1.0 for some reason
Also, this looseness seems to be limited by the value density defined by the previous variables (Points Per Squared meter and Point Extent). By this I mean that if you choose an extent big enough to have all your poins in contact (for exemple 0.1 point/m² with an extent of 200x200), then even a looseness of 1.0 (or above) won’t change anything. But with an extent of 50x50, then it’s working (in a range from 0.0 to 1.0 only)
So I don’t know if this is really a bug or a voluntary change in behavior, but it’s kind of confusing.
