Polywire SOP.. non uniform line radius possible?

[art3mis]

Trying to use Polywire SOP with a line and a Carve SOP so that the radius of the line is different along its length.

However any changes to the Wire Radius in Polywire always affect the entire line length.
Is there any way to accomplish this?

I'm not sure about Polywire, but the Sweep SOP could handle such variation, as it already knows about the "pscale" point attribute.  Either with a ramp-driven point wrangle, or something like MOPs Sweep Spline, if available.

float ramp_pos = fit(float(@ptnum), 0, @numpt, 0, 1);
f@pscale = chramp('Sweep_Profile', ramp_pos);

Wrangle:

Hey thanks!!

Polywire also natively supports variable width; just made a float attribute on your points and use it as the "wire radius" value (e.g. @width)
