Animated GLB to Blender: Import, Keep One Walk, Export

A model moving in one preview is only half the check. Reopen the exported file and make sure it still moves. This demo takes a CC0 Quaternius character with 17 clips through Blender, keeps one walk, and saves a self-contained animated GLB.

Playback of the exported GLB in Blender. Silent clip; the steps and checks are below.

You can download the source and finished result without a Cinevva account. The character and walk are authored assets. No AI generation or new auto-rigging is involved.

What you need

• The original character GLB, including its 17 animation clips.
• Blender. The steps and result here were checked with Blender 5.0.1; export labels can differ in other versions.
• The walk-only result as a reference if your export behaves differently.

1. Import the source into a clean scene

Open a new Blender scene and remove the default objects. Use File → Import → glTF 2.0, then choose character-source.glb.

The import should contain an armature and every character mesh part. This sample uses material colors and has no external image textures, so you do not need to locate a separate texture folder.

2. Choose the walk

Select the armature. Change an editor to Dope Sheet → Action Editor, choose the source's Walk action, and play it in the timeline. If an action-slot selector appears, use the imported armature's slot. Check that the character's body follows the bones; a moving skeleton with a stationary mesh is not a successful import.

Keep only the intended walk active for this example. Mute the other NLA tracks: an unrelated active strip can change what plays or exports. Keep the source file with all 17 clips so you can return for other motions later.

3. Export a new GLB

Use File → Export → glTF 2.0 and select glTF Binary (.glb). Enable animation export. In Blender 5.0.1, use Animation Mode → Active actions merged for this one-clip example.

Export the clean scene with the armature and all its mesh parts. If you use Selected Objects, select both the armature and every required mesh; selecting only the armature leaves out the visible character.

Save as a new file, such as my-character-walk.glb. This mode combines the assigned active actions into one clip; it does not export every action in the original file. See Blender's glTF import/export documentation for other animation modes.

4. Reopen the file you actually exported

Create another clean scene and import my-character-walk.glb. Play its animation. Check these four things:

1. All body and clothing parts are present.
2. Materials look correct without files from your original working folder.
3. The mesh deforms with the walk, including at the elbows and knees.
4. The intended clip survived, and the start-to-end transition is suitable for your use case.

This catches omissions that stay hidden while the source scene is still open. The result can also be inspected with the Inspect the result in 3D button above.

What we verified

The source was imported, a walk exported and the resulting file reopened in Blender 5.0.1 on November 7, 2026. The clip above is rendered from that result.

Check	Source	Walk-only result
File size	1,759,956 bytes	476,132 bytes
Animation clips	17	1
Triangles	6,624	6,624
Joints	23	23
External image or buffer dependencies	None	None

The smaller download comes mainly from keeping one animation instead of 17. It is not a compression comparison with identical content. The exported clip is named Animation; the source's action name and the exported clip name do not have to match.

See verification details and hashes. This verifies the Blender workflow for this sample. Unity, Unreal and Godot imports were not tested, and a numerical deformation check is not a full assessment of foot contact or animation quality.

When your own model behaves differently

• Pink or missing textures: inspect the source for external image references. A .glb extension alone does not guarantee that every resource is embedded.
• The skeleton moves but the model does not: check skin weights and armature assignment before exporting again.
• No animation after reimport: check the active action, NLA tracks and animation-export setting. Confirm you imported the new file, not the original.
• Some body parts are missing: export the full clean scene, or include every mesh part in your selection.
