Blur Node does not work with sampled landscape points

Hi there,

i have this super simple setup, where i am sampling my landscape. I now want to blur the Forest attribute but the resulting attribute is sometimes NaN, sometimes -inf, often times just 0 or some 2 billiion+.

Feels like something is going wrong like a division by zero, but the search distance should definitely capture some neighbour points.

When i have the same setup with a “Create Point Grid” node everything works smoothly.

Any suggestion will help, thanks!
