BOBJ Exporter Online — Free Browser Converter for Minecraft Animated Models by KAG3D
What is BOBJ Exporter Online?
BOBJ Exporter Online is a free browser tool by KAG3D that converts animated 3D models from GLB, GLTF, and FBX formats into the BOBJ format used by the Minecraft Blockbuster Mod. It is based on mchorse's original io_export_bobj Blender addon, ported to run entirely in the browser.
What is BOBJ?
BOBJ is the 3D model format used by the Blockbuster Mod for Minecraft Java Edition, developed by mchorse. It is part of the McLib ecosystem and supports animated models with bone-based skeletal animations. BOBJ files are used to create custom animated entities, props, and characters in Minecraft machinima productions.
Supported Input Formats
- GLB — binary GLTF format (recommended)
- GLTF — JSON GLTF format with separate assets
- FBX — Autodesk FBX format with animations
How to Use

- Click Export to download the BOBJ file
- Import the BOBJ into Minecraft via the Blockbuster Mod
