XPS to FBX converter: XNALara into an engine

Zip the .xps, .mesh or .mesh.ascii with its textures and drop the zip. Out comes one binary FBX with the skeleton, the weights and the textures embedded.

Other converters:Animation → VRMAVRM → FBXVRM 1.0 ↔ 0.x

What comes across, and what cannot

Comes across

  • · The skeleton and skin weights
  • · Materials and textures, embedded in the FBX
  • · Render groups as separate meshes

Does not

  • · XPS pose files: a pose is not in the model
  • · Facial expressions driven by XPS bones stay as bones, not shape keys
  • · Optional items toggled in XPS: every mesh is written

How to convert XPS to FBX

  1. Zip the model folder with its textures and drop the zip. Up to 100 MB.
  2. The model is read on our server with our own XPS importer and written as a binary FBX.
  3. Preview the FBX in the browser, download it. Both files are deleted 3 days later.

Which XPS files work

The binary .xps and .mesh forms and the text .mesh.ascii are read, from any XNALara or XPS release. Textures are matched by the names in the model, so keep the folder as it came. Render-group flags (alpha, specular, bump) are read where they map onto PBR; the rest is dropped quietly.

Where the FBX goes

Unity, Unreal, Maya and Blender open it textured. For a VTubing avatar, convert the FBX further on the FBX to VRM converter; the skeleton usually maps once the bones are named after a known convention.

Questions

What do I upload?

A zip of the model folder with its textures. The model file alone converts grey.

Are the textures kept?

Yes, embedded in the FBX.

What about poses and expressions?

Poses are separate files and are not part of the model. Expressions driven by bones stay as bones.

Can I use the model in a VTuber app?

Convert the FBX to VRM on the FBX to VRM converter; many XPS rigs map, some need renaming.

Something came out wrong.

Write to support@shapeweld.com with the job id under the result.

May I convert a model I downloaded?

Only within its terms; many XPS models are rips with no licence to convert.

Onward to VRM

The FBX from this page goes into the FBX to VRM converter when the goal is a VTubing avatar.
