I made a Geometry Node, which transforms a given Curve into a street. While the curve has the same value vor Z, it looks fine (Picture 1). When I start playing with the Z values tho, the road starts rotating inward. How can I keep it from doing that? Basically, I want the Normals local X Value 0.

If possible, I want to solve that in Geo Nodes.

Thanks in advance :D

While Flat While Changed Z Value

Set Twist method to Z-Up in curve properties:

  • $\begingroup$ This is what I was looking for, thanks. Is there a way, to do that in geometry nodes tho? $\endgroup$ Mar 16, 2022 at 10:13

  • $\begingroup$ @Kralkaz-.- Before the Curve to Mesh node add in a Set Curve Tilt node with 0°, this should reset all tilting in the curve. But additionally use the Twist Method > Z-Up in the Curve Properties as well. $\endgroup$ Mar 16, 2022 at 11:07
