Robot Designer earns its place in the superhive library by automating the whole humanoid robot pipeline — from procedural geometry through to rigged, export-ready characters — so the decisions stay with you while the build work is handled by the tool.
Robot Designer is a procedural character creator that builds a complete humanoid robot inside Blender. The workflow runs in five steps — geometry, materials, rig, UV, bake, and export — with each step handled automatically. You pick one of ten hand-crafted presets, adjust sliders, and the tool produces the result.
Geometry is driven by geometry nodes with over 800 parameters spread across six categories per body part, and every change is instant and non-destructive. A PBR smart material built for hard-surface robots is applied automatically, with per-zone control over the base mesh, plates, joints, eyes, details, cables, and screws. It renders in both Cycles and EEVEE, and an ID map is generated for Substance Painter with no manual masking.
Two rigs ship with the tool: a Rigify IK/FK rig and a Mixamo rig, both using custom hard-surface skinning. Atlas baking covers all seven map types, LOD generation is included, and export supports FBX, OBJ, and GLB with presets for Unity, UE5, and Sketchfab. The V2 release rebuilt the material system, added Rust and body-type controls, and corrected the rig rotation axes.
Robot Designer - Procedural Robot Character Creator is best for blender users creating humanoid robot characters who want procedural geometry, included rigs, and export-ready assets for engines like Unity and UE5.
Robot Designer - Procedural Robot Character Creator is completely free to download and use.
Robot Designer's V2 release is available for Blender 4.5.4 and later. It runs the full humanoid robot pipeline inside Blender, covering geometry, materials, rigging, UV, baking, and export. The procedural geometry is built on geometry nodes, and its PBR smart material renders in both Cycles and EEVEE. If you are on an older or specific Blender build, check the developer's page to confirm which versions are supported before installing.
Robot Designer includes two rigs: a Rigify IK/FK rig and a Mixamo rig, both applied with custom hard-surface skinning that avoids artifacts. In V2, the Rigify and Mixamo rotation axes were corrected for accurate, predictable animation. The Mixamo rig is now fully compatible with Cascadeur and the official Mixamo Blender addon, so you can move robots into those external animation pipelines. This gives you rigged characters straight out of the tool.
Robot Designer exports to FBX, OBJ, and GLB, and includes LOD generation. It ships with export presets for Unity, Unreal Engine 5, and Sketchfab. Texture work is covered too: atlas baking handles all seven map types, and an ID map is generated for Substance Painter with no manual masking. UV unwrapping runs automatically when you finish a robot, and the smart material renders in both Cycles and EEVEE.
Robot Designer V2 is a major update and a free update for existing owners. The material system was rebuilt from scratch, adding a Rust slider alongside Wear, unifying wear into a single global slider, and adding five plate color patterns. Geometry improvements include legs that spread with hip radius, a redesigned shoulder joint, and smoother cables. Three body-type presets — Muscular, Average, and Skinny — were added at generation time. Rigging axes were corrected, and the Decimate and ID map baking bugs were fixed.
Robot Designer is listed as free in this catalog. Licensing terms are set by the developer, so check the developer's page for current details before you rely on it for a project. The developer offers a personal license, and the V2 update is provided free to existing owners. For the most accurate and up-to-date licensing information, refer directly to the developer's listing.
