Help with Smooth Falloff & Control for Cable Generator in Geometry Nodes

[Niko_Pekkarinen]

Hi!

I’ve been working on a cable generator using Geometry Nodes for a setup where a moving vehicle lays down a cable behind it.

So far, I’ve managed to create a basic cable system that shrinkwraps to the surface. However, I’m struggling with two key aspects:

1. Smooth Falloff Before Touching the Ground

• Right now, the cable snaps too abruptly to the surface.
• I’d like to create a smooth transition from the vehicle to the ground, so the cable gradually settles instead of instantly following the shrinkwrap.

2. Control the Cable’s Position on the Ground with an Empty

• Ideally, I want an empty object to adjust the cable’s shape in the X and Y directions once it’s on the ground, allowing some flexibility in its path.

Do you have any recommendations for how to achieve these effects in Geometry Nodes? Thanks in advance for your help!

Smooth Falloff Before Touching the Ground

You can look into the blur attribute node for that, blurring the point’s position between the raycast and the set position should give you something…

Then for controlling the curve position , you can try that :

All the emptys are stored in one collection…

Have fun !
