Spline Mesh Builder

Notion Properties

Purpose

Builds modular roads, rails, pipes, trims, and other repeated runs along an editable spline path with Bezier handles, per-point banking and width shaping, terrain projection, and optional junction markers.

How to Use (Step-by-Step)

1. Open Spline Mesh Builder from the Modeling menu and create or assign a spline profile asset, or generate one of the included starter profiles for roads, rails, or pipe runs.
2. Add or load spline points, then use Bezier handle editing or Auto Smooth Handles when you want a curved path instead of a pure polyline.
3. Set the placement mode, prefab forward axis, segment length, segment scale, global bank, and any per-point roll, width, or local offset overrides.
4. Enable projection if the spline should follow terrain or graybox surfaces, and choose whether the generated pieces should align to the detected surface normal.
5. Assign a segment prefab for the repeated run and an optional junction prefab for control points flagged as junctions.
6. Fill in path role and lane metadata if the spline run should carry reviewable design semantics in the exported JSON report.
7. Generate the spline mesh to place repeated or stretched segments under a managed output root, then export the report when you want a placement manifest for review or handoff.
