GTLF to FBX converter for 3D models

Hello virtual creators and gaming enthusiasts! Have you ever wondered, “How to convert a GLB to an FBX file?” or “Can I use my Avaturn avatar in a game engine like Unity or Unreal Engine?” If so, we’ve got some exciting news for you!

Avaturn, the leading platform for creating realistic avatars and provider of the most realistic Avatar SDK, has just rolled out a brand-new tool: a GLB to FBX converter. This new tool allows to convert GLTF (GLB) to FBX online, free and with textures. The FBX will work in Blender, Unity, Unreal and other engines. While it’s initially designed to work with 3D avatars generated by Avaturn,it actually works with any GLTF (GLB) file.

Converting GLB to FBX is a simple process. Start by exporting your unique Avaturn avatar as a GLB file. Then, use our newly introduced converter to transform it into an FBX file, ready to be imported into your game or app.

To make this process even smoother, we’ve created detailed step-by-step tutorials on how to import your newly created Avaturn avatar or any other GLTF 3D model into Unity and UE.
