Random spline thickness

[paul.clements]

I have a single object which is many individual splines along a flat surface.

Is it possible to give each spline a random thickness? Each spline should be uniform in thickness but just different from each other... Any help is much appreciated!

There's no way to randomize the radius currently, I'm afraid. It would be a nice addition in a future version though. Your only option currently is using a tool where you can control thickness on the geometry level (e.g. xp trails).

Thanks Peter. I had another question also re. curves....

Is it possible to colour the curves in order? So curve 1 is white and curve 100 is black? I have been experimenting with curve_id but no success as yet.

That should be it. user_data_int with curve_id as the attribute, connected to a range shader to map [0, N] to [0, 1]. The order is how the splines defined in the object. You might need a ramp as well to set from white to black.

That has worked brilliantly, I was missing the range shader. Much appreciated, thanks Peter

Thickness can now be randomized per spline in C4DtoA 4.2.3.
