LiveryHelper earns a spot in the Blender extensions library by leaning entirely on Blender's built-in nodes, which keeps projects portable and lets liveries bake down to a texture or transfer between vehicles. A BlenderArtists discussion thread and a compact file size round it out.
LiveryHelper by Mast26 makes creating, editing and customizing car liveries easier in Blender. You select a source image, add metallic and roughness maps if you want them, choose a base color tint and a blend mode (add, multiply or mix), then apply the livery to the selected mesh. Each livery can be moved, rotated, scaled, and mirrored to the other side of the car automatically.
Liveries can be applied Planar, projected onto the car like a sticker, or with Box (Triplanar) projection for large tiling textures. All of this uses Blender's built-in functionality, generated as a Node Group plus an Empty that controls the projection's position, rotation and scale. Because everything resolves down to albedo, metallic and roughness outputs into a Principled BSDF shader, liveries can be baked to a texture, and the UV-map-agnostic setup can be transferred to other vehicles by applying the material to another object.
Since projection is based on the Empty's transforms, you can export these into Unity, Unreal or Godot as decal projectors. LiveryHelper isn't limited to car liveries; it works for anything that needs images projected onto meshes, such as decals.
LiveryHelper is best for blender artists building car liveries or projecting decal images onto meshes.
LiveryHelper is completely free to download and use.
LiveryHelper is compatible with Blender 4.2 LTS and newer, so any release from 4.2 onward should run it. The current version is 1.0.3, published in August 2024. It requests a single permission, file access for loading source livery images, and is distributed under the MIT License. You can drag and drop the download straight into Blender or install it from disk through Blender's extensions preferences.
LiveryHelper works from a couple of clicks. With your target mesh selected, choose a source image, set the color tint, blend mode and spawn orientation, then click "Apply Base Livery Material" to add the base material. Next click "Spawn Livery at 3D Cursor" to place the livery at the 3D Cursor using the orientation you picked. Repeat the spawn step to add more liveries onto the same mesh. Each one can then be moved, rotated, scaled or mirrored to the opposite side of the car.
LiveryHelper builds each livery from a Node Group and an Empty, and because the Material/Empty setup is UV-map agnostic, you can transfer a livery to another vehicle by applying the material to a different object. You will need to move the new car into the same position and reposition the Empty projectors, but that is easier than rebuilding it from scratch. The same node setup also resolves to albedo, metallic and roughness outputs into a Principled BSDF shader, so liveries can be baked to a texture.
LiveryHelper isn't limited to car liveries. It can project images onto any mesh, which makes it usable for decals more broadly. Because the projection is driven by the Empty's transforms, you can also export the setup into engines like Unity, Unreal or Godot and use them as decal projectors if you want crisper decals. Both Planar (sticker-style) and Box/Triplanar projection are available, with the latter suited to large tiling textures.
LiveryHelper is listed as free in this catalog and is released under the MIT License. The add-on is a compact download, around 5.1 KB, and it requests one permission: file access for loading source livery images. There is also a LiveryHelper thread on BlenderArtists if you want community discussion. For the most current licensing and download details, check the developer's page.
