Hi guys, I am a beginner for Houdini and I got question that makes me confused.

I wrote a VEXpression and run it on Points. (There are 100 points) So does this expression run on every single point? Or it will just run only time.

I thought it should be run on every single point, but actually it only run one time, also it effects all the points. How does it happen?

Sorry for my English...

it runs on every single point (within group) independently

so :
will take the current i@num value of a point and adds 1 to it
so if every point had i@num = 0 (or if there wasn't i@num attribute on the geo yet) then i@num value for each point will become 1
