Kiln
An AI copilot for 3D modelling.
Describe what you want and Kiln's copilot builds it in Blender, in the background, while you watch it take shape in a live 3D viewer. Models come out game-ready, and Kiln can bake them for Roblox.
Version 0.8.7 · 187 MB installer · Windows · MIT license · setup guide
Comes with Shuriken Studio
Kiln is made to work with Shuriken Studio, the AI game studio for Roblox: its agents send Kiln model briefs, and Kiln sends finished models into Roblox Studio through it. One installer sets up both.
Yours to change
Kiln is a gift: take it and make it your own. The full source comes with it under the MIT license, ready for you or your own AI coding agent to read, change and extend. When a new version is out it asks before updating, so a copy you've changed stays yours.
What it does
Built for Roblox creators
Chat to model
The copilot writes and runs Blender Python, looks at its own renders, checks its work and fixes what it finds. Every change is a version you can undo.
A live viewer
Orbit, select a part (the copilot knows what you picked), wireframe, clay, turntable, and a Roblox lighting preview.
Built for games
Hard-surface shells, organic shapes, trees, rocks, terrain, a building kit, materials and creatures, in a tested modelling library.
Rigs and animation
Armatures and generated clips (walks with planted feet, idles, attacks, hits) you can scrub, blend and tweak with sliders.
Roblox-ready export
Plain PBR, triangle budgets and one baked atlas per model, with a manifest a game tool can import.
Every format
GLB, FBX, OBJ, STL and .blend downloads.
