Install the AI Toolbox
Blender Forge comes with the AI Toolbox. Paste the install prompt with your key into Claude Code, or join the free beta to get one. You need Blender 4.2 or later (it's tested on Blender 5.2).
Ask what it can build
Say “What can Blender Forge build?” Claude runs the
modelsaction and lists every model this version can build, with a line on each, so you can pick by name.Build it live or in the background
Say “Build the furnished tower in my open Blender.” A live build goes into its own scene in the Blender you have open, so you can look around straight away. A headless build runs in a background Blender and saves a .blend file, with GLB, FBX or OBJ export.
Let Claude check its own work
Every build returns a turntable review sheet: the model seen from all round, with its size in meters. Claude reads it before calling the job done, which catches the problems a single viewport screenshot misses.
Render, or export to Unreal
Ask for renders and Forge renders the scene's cameras with Cycles on your own GPU. For games, it exports homes, public buildings, props and vehicles as FBX with baked textures and collision, ready to import into Unreal Engine.
Things you can say to Claude
- “Build a furnished two-story home from this floor plan.”
- “Make the penthouse floor brighter and render it from the living room camera.”
- “Export the corner store as a game asset for Unreal with collision.”
Good to know
- Blender uses Z-up and meters; Forge builds to real sizes, so imported assets match a real-scale Unreal level.
- Characters are built from MakeHuman's free CC0 bodies on a skeleton that uses the Unreal mannequin's bone names, and export as Unreal skeletal meshes.
- Everything runs on your own computer; nothing is uploaded.
