Hey guys
I would like to ask how to know how many primitives in one node? I mean automatically, because I don't want to count them one by one.

For example, I have this node which contains 8 primitives, How to get the 8 out of it, since it shows that the max prim num is 7. I want to use prim num “8” as a variable in Wrangle. Thank you very much.

if you middle mouse click on a node it will tell you lots of information about the geometry
if you have 8 prims, their numbers will be 0 - 7, since counting begins at 0

Thank you for replying, however, what I actually need is that if there is a vex API that I could get the number?

I need that “8” automatically, no matter how many primitives, I could always get the number without a middle mouse check?

nprimitives VEX function
Returns the number of primitives in the input or geometry file.

Thanks, man. I think this is the answer to the question!

In an attribute wrangle, @numprimwill evaluate to the number of primitives in the first input.
