Geometry Nodes Development Discussion

[zeroskilz]

Try my z-up curve tilt group (file at top of linked thread) - takes in custom normal so when transferring normals using closest surface you can follow a surface:

"Z-Up Curve Tilt" NodeGroup for Blender 3.0 (Geometry Nodes)

Note on an update to file at the beginning of this thread: This node-group now supports a “custom alignment vector” input, allowing for things like sweeps to conform to underlying geometry: [image] Note geometry with multiple “loops” will still cause resetting “twists” when a loop happens. Work followed on from this thread.

Good luck!
