Loop Copier earns its place in the superhive library for a focused job: repeating a mesh along an edge loop while keeping each copied part undeformed, which sets it apart from an Array-plus-Curve modifier setup.
Loop Copier duplicates a source mesh along a selected edge loop in Blender. Unlike combining the Array and Curve modifiers, which bend and deform the original mesh, this tool copies parts without deforming them. It works on closed loops, open-ended edge lines, and existing edges of a mesh.
The add-on suits hard-surface structures such as tanks, bullet magazines, and chains. You can set the number of copies and adjust rotation, scale, and offset. A "Follow curve surface" option places copies on curved surfaces using the face normal.
Using it takes two steps. Switch to Edit Mode and Edge select mode, pick the source edge loop, then choose "Set Edge Loop" from the Loop Copier entry in the right-click context menu. Next, select the mesh to copy and choose "Copy to" to set the count, offset, and the other options. Loop Copier supports Blender 2.83 through 5.1 and is marked Blender Extension compatible.
Loop Copier is best for hard-surface modeling of repeated structures such as tanks, bullet magazines, and chains.
Loop Copier is completely free to download and use.
Loop Copier supports Blender versions 2.83 through 5.1 and is listed as Blender Extension compatible, so it covers a wide span of releases. Note that an earlier Geometry Nodes mode was removed in version 2.5.0 because it had stopped working, so the current build focuses on the core edge-loop copying rather than a node-based setup. The developer mentions possibly adding that mode back in the future. For exact behaviour on your specific Blender version, check the developer's page.
Loop Copier must be installed from its zip file without unzipping it first. If you extract the archive and install the loose files, Blender will not install the add-on correctly and errors can follow. Should that happen, uninstall the add-on, remove the unpacked files, and reinstall by selecting the zip during installation. One more modeling note from the developer: scale objects in Edit mode rather than Object mode, since scaling in Object mode can confuse Blender's mesh data for the add-on.
Loop Copier can place copies on curved surfaces. A "Follow curve surface" option, added in version 2.2.0, positions the mesh on the selected edges of a curved surface using the face normal. The tool also handles closed loops, open-ended edge lines, and existing edges of a mesh, so it is not limited to flat or straight arrangements. For details on enabling and setting this up, see the developer's page.
Loop Copier differs from combining Blender's Array and Curve modifiers. That modifier combination bends and deforms the original mesh, since the Curve modifier bends it. Loop Copier instead copies the mesh parts along the selected edge loop without deforming them, which the developer describes as well suited to hard-surface structures such as tanks, bullet magazines, and chains. If keeping each copied part undeformed matters for your model, that is the distinction to weigh.
Loop Copier is listed as free here in our catalog. Licensing and pricing can change over time, so the developer's page is the place to confirm the current terms before you rely on any particular arrangement. The add-on comes from KushiroCG, targets Blender, and is marked Blender Extension compatible, supporting versions 2.83 through 5.1. For the most up-to-date licensing information, or if you have questions about the product, the developer's page and listed contact options are the best route.
