Applying noise to a curve with fixed points

Recommended Posts

Hi all, really noobish question here, but how would i apply some turbulent noise to a curve in VOP's while having the end points unaffected.

i know about the $PT/$NPT expression but that only gives me the desired effect on one end of the curve, how would i go about having it on both ends?

Thanks in advance

Simplest way would be to get an attribute that is 0 at one end of the curve, 1 at the other, then use a vop ramp parameter (or wrangle ramp parameter) to remap that value so its 0 at each end, and 1 at the middle. Use this to scale your noise.
