transfer expression to every primitive

[Stanislav]

hello how to pass an expression to each primitive, now the gradient is applied to everything. thanks

made with nodes for each

nice looks like you've got it. here's another solution using just the one wrangle like you tried originally:

(Run Over: Primitives)

int pts[] = primpoints(0, i@primnum); // List of points on the current prim
int numpt = len(pts);
for (int i = 0; i < numpt; ++i)
{
    float grad = float(i) / (numpt-1);
    float ramp = chramp("ramp", grad);
    float pscale = fit01(ramp, chf("pscale_min"), chf("pscale_max"));
    setpointattrib(0, "pscale", pts[i], pscale);    
}
