I want to play niagara made using Niagara Plugin in sequence.
In normal niagara, it is possible to control in sequence,
but niagara using HNJSON can not be repeatedly played and controlled.

vector Varray;

for(int i = 0; i < @numpt; i++)
{
vector TempVector = point(0, "P", i);
push(Varray, TempVector);
}
i@templen = len(Varray);

for(int n = 0; n < @lengthW; n++)
{
for(int i = @LastValue * n; i < @LastValue * (n + 1); i++)
{
for(int j = i+1; j< @LastValue * (n + 1); j++)
{
vector ComTemp1 = Varray;
vector ComTemp2 = Varray;

if(ComTemp1.z < ComTemp2.z)
{
Varray = ComTemp2;
Varray = ComTemp1;
}
}
}
}

for(int i = 0; i < @numpt; i++)
{
vector lastVec = Varray;
//setpointattrib(0, "P", i, lastVec, "set");
}
I want vector Ascending
but
why "setpointattrib(0, "P", i, lastVec, "set")" <----- crash???

I am currently using Houdini Indie version.

I tried to reder all in VAT node by choosing RBD dynamic mode, and wanted to run in UE4.26.
However, it doesn't properly work in UE4.26.
What can I do?
