What the difference between $VTX and @vtxnum?
Using $VTX with the point-old node gives 0,1,2,3,0,1,2,3,0,1,2,3 etc
Using @vtxnum in the wrangle node gives 0,1,2,3,4,5,6,7,8,9,10,11…

$VTX used to return vertex number within a primitive
@vtxnum returns linear vertex number across the whole geo

to get the same result as with $VTX you can use vertexprimindex(0, @vtxnum);
