Animation Combiner 3D

Combine multiple FBX animations into a single character file — quickly and completely offline.

Animation Combiner 3D is a simple tool that helps game developers merge multiple animation clips into one rigged 3D character. Perfect for workflows using Mixamo, Blender, Unity, Godot, Roblox, or any engine that supports GLTF/GLB.

No internet connection required. Just import, preview, combine, and export.

> Features

• Import FBX character in T-pose
• Add multiple FBX animation files
• Preview animations in real-time 3D viewer
• Adjust animation speed
• Loop animation playback
• Combine animations into one file
• Export as GLTF (.gltf)
• Export as GLB (.glb)
• Drag & drop support
• Works fully offline
• Minimalistic black UI

> How to use

1. Import character FBX (T-pose)
2. Add animation FBX files
3. Preview animations
4. Click "Combine Animations"
5. Export as GLTF or GLB

Exported file includes: character mesh + skeleton + all animation clips

> Why use this tool?

Combining animations manually in 3D software can take time. This tool speeds up the process and keeps everything organized in one file.

Useful for: • game development • animation workflow • prototyping • asset preparation

> Supported formats

Input: FBX (.fbx)

Output: GLTF (.gltf) GLB (.glb)

> Notes

• Character should be in T-pose for best results
• When using Mixamo animations, the software can automatically create the correct T-pose
• All animation files must use the same skeleton structure
• Bone names must match between character and animation files
• Best results when character and animations come from the same source (for example Mixamo)

If bone names are different, animations may not apply correctly.
