Drag an existing curve
- Open a graph and select Hand Edit: Drag to shape. Turn Foliage off if the canopy obscures the structure.
- Left-drag anywhere on a green curve. Nearby points move smoothly and the base stays attached. White dots mark control positions; selecting a dot first is unnecessary.
- Release to rebuild. Rotate the camera to adjust another plane. Alt/right mouse navigates; Escape cancels the stroke.
Draw freely
Redraw curve replaces the picked spline shape from its base. Draw trunk starts a new stroke on the camera-facing plane through the origin and creates its mesh path. Draw branch and Draw root start on a picked curve and add a tapered spline to that output. Rotate the view and use Drag to shape to refine depth.
Editable graph history
The first committed edit inserts Hand Modification immediately after the selected curve output. Every original consumer connects to its output, including branch generators and mesh nodes. Further strokes on that modifier stay in its Strokes array. Edit stored points in Details, disable Enabled to compare the procedural shape, or delete the node to reconnect its original input to its consumers. Undo and redo cover the edit and wiring together.
The viewport overlay shows source curves before downstream Transform or placement nodes. Shape those curves before applying placement transforms. Strokes store shapes in the source curve's local metres. Existing spline edits preserve procedural radii and sample count. Changing upstream branch counts or seeds can change which spline occupies a stored index; review hand edits after structural recipe changes.
