RoadMarker
by Ievitan
RoadMarker is a Fabric server-side builder tool that places smooth subpixel curves, road markings and curbs using stairs and coral fans.
What it does
Players work through a wand in the game world. Before any block changes, particle previews show the planned path, so a route can be checked first. Straight lines between two points, Bezier curves with any number of control points and Catmull-Rom splines that pass through each control point are all available as curve modes.
Lines are rasterized on a 2x2 subpixel grid, with a global dynamic programming pass that chooses block placement. An automatic curb generator bevels a road edge toward the surrounding terrain, and the mod supports two materials in one build.
Only the server needs RoadMarker, so players join without installing it. The mod is built for Fabric and is also offered for Paper, with a single file, 1.1.0 for 26.2, published on 2026-09-23. The code is under the MIT License and is not open source.
Key features
Wand-based workflow
A wand selects points and modes, so curves are placed directly in the world without commands.
Curve modes
Straight subpixel lines, N-point Bezier curves and Catmull-Rom splines cover different road shapes.
Curb bevels
The automatic curb generator bevels road edges and diagonal curbs toward the surrounding terrain.
In-place smoothing
Existing full-block lines are converted into smooth stair curves with a single click.

Use cases
Road markings
Lane lines and curves are drawn with smooth edges rather than stepped block lines.
Curved paths
Spline paths bevelled with stairs or coral fans suit parks, gardens and winding trails.
Who it’s for: Builders who lay out roads, paths and curbs on a Fabric or Paper server, and server owners who want these tools without requiring players to install a client mod.
How it compares
SplinecartUnlocked is a Fabric mod for 26.2 that runs on client and server and is open source under the MIT License, so it needs installing on both sides. Subpixel Cushions is server-required for 26.3 on Fabric, Forge, NeoForge and Quilt, with client installation optional, and is released under the MIT License without being open source.
