How to remove points from render

[pizola 0]

I was following a tutorial from @librarian (a nice dude) but i stepped on the following problem:

the points render and at sop level appear. I have everything exactly the same on my proyect as the tutorial and still they appear on sop so they end up rendering

It should look like this:

My proyect

grilla3.hip

Model

solu2od.hipnc

 

Thanks a lot

you can remove point with neighbourcount function

int neighB==neighbourcount(0,@ptnum);
if (neighB==0)
removepoint(0,@ptnum);
