RutForge paints accurate supercross and motocross ruts straight onto a grayscale heightmap for MX Bikes and other motocross games, at real-world scale, with a live 3D preview and true 16-bit PNG export.
Runs entirely in your browser. Your heightmaps never leave your machine.
This is the real cross-section engine from the app. Drag the sliders to sculpt the channel and berm - depth, width, sharpness and fade are all independent.
Sketch ruts by hand, or drop precise anchor points and pull smooth curves like a vector pen tool. Either way you get the same clean, scaled rut.
Each rut you place lands in the Layers panel. Select one to reshape it, group several to edit them together, and rename, hide, reorder or delete any of them - non-destructively.
Flip on the 3D view to watch the ground deform in real time as you carve. It's shaded by slope so even subtle ruts read clearly, at true X / Y / Z scale.
Found a rut shape you love? Save it as a preset, then import and export presets as files to reuse across projects or share with your crew.
.rutpreset.json
Save everything as a single .rutforge project file - the original heightmap, every rut, your layers, groups and settings. Re-open it any time to keep going exactly where you left off.
Import a heightmap, carve your ruts, export a true 16-bit PNG. No account, no install.
