Commit: 29d6750134c4e42a2c5ff12040aa78f98720cf5c Author: Johnny Matthews Date: Mon Jul 5 12:27:12 2021 -0500 Branches: master https://developer.blender.org/rB29d6750134c4e42a2c5ff12040aa78f98720cf5c
Geometry Nodes: Curve Primitive Line This node creates a poly spline line in one of 2 modes: - Line between two points - Start Point, Direction, and Length Both modes create splines with only start and endpoints. A resample node can be used afterward to increase the point count.
