Racetrack Helper

Racetrack Helper v4

A Blender add-on for working with racetracks and their surrounding environments. Racetrack Helper helps you create geometry around roads and organize your scene. Build transitions between track edges and surrounding terrain, connect mesh sections, and process multiple objects at once: replace texture paths, organize object names, and clean up materials.

The add-on is designed for racetrack creators, modders, and environment artists working with polygonal models in Blender.

Geometry Around the Track

• Road-to-terrain transitions. Create optimized polygon transitions along selected road edges. Adjust the width, number of strips, and mesh density reduction as the geometry extends away from the track.
• Adaptation to existing terrain. Select a surface object to generate transitions that follow its elevation.
• Working with nearby sections. Intersection limiting and adjacent boundary connection settings help handle narrow gaps between track sections.
• Extending the surrounding terrain. Extend the mesh from a closed outer boundary to a square outline, with adjustable size, rotation, density, and height alignment.
• Connecting edge loops. Bridge two open or two closed edge loops, even when they have different vertex counts.

New geometry can be connected to the original mesh or created as a disconnected section for later separation into a standalone object.

Scene Organization

• Texture path replacement. Batch-replace image paths with files from a selected folder — for example, replacing DDS textures with pre-converted PNG files that have matching names. Missing files can be skipped.
• Material processing. Merge materials based on matching base textures and selected settings, remove unused material slots, and switch materials from Alpha Blend to Opaque mode.
• Object processing. Join selected meshes based on their first material, remove isolated vertices, and apply object scale.
• Batch renaming. Rename objects with sequential numbering and synchronize mesh data names with their corresponding object names.
• Quick selection. Select objects by material, all visible mesh objects, or empty mesh objects.
• UV map switching. Select an existing UV map by index across multiple meshes and set it as the active render UV map.

What to Know Before Purchasing

Racetrack Helper is a collection of tools for modeling and scene processing. Terrain operations require prepared geometry and selected edges. Complex areas may require manual adjustments. The add-on does not generate an entire finished racetrack automatically.

Texture path replacement requires pre-existing image files and does not convert textures. UV map switching works only with existing UV maps.

The add-on panel is located in the 3D Viewport sidebar: N → Racetrack Helper.
