Hello,
I need small spheres to be deleted if the large spheres intersect them.
Is it possible?

I went the rough way: Realize Instances and Raycast them on points.
Is there a way without Realize Instances?

You can use a geometry proximity testing for the combined radii on the points pre-instancing:
Good luck

Nice tip if you don’t need to randomize large spheres scale.
Otherwise I think, no way without Realize Instances.
What I’m trying to achieve:
- Big spheres with random scale 1 to 0.5
- Small spheres with 0.4 to 0.2
- Tiny spheres with 0.15 to 0.05
that made me use Realize Instances two times

i like your solution, but just a small improvement suggestion: with node groups, it looks like this:
…and i think it is easier to understand
