frozer

Hello,

Im pretty new to houdini, and i got a little problem.

For my project i made a champer, which includes a floor, a few pillars, and a road. Now this floor isn't perfectly flat, and my road is going in a curve (this curve is also going upwards) Now i want these pillars to go between my floor, and my road. This means every pillar has a diffrent height, based on the height of my road and my floor. Now for this i tried the Ray node and a copy node with the $DIST stamp, but it doesn't seem to work properly.

Anyone here he wants to help me out?

Cheers
