UVs Flip Vertically on Export from Nomad Sculpt

PLATFORM: iPad Pro
NOMAD APP VERSION: 2.8

When exporting models from Nomad Sculpt, the UVs are automatically flipped vertically.

Imported models from other software such as Autodesk Maya and Blender display their UVs correctly inside Nomad Sculpt. However, after exporting from Nomad Sculpt, the UV layout appears vertically flipped in other applications. UVs should remain consistent and not flip during export.

This becomes especially problematic when working with UV layouts that are already set up for texturing.

Steps to reproduce:

  1. Import a model with UVs into Nomad Sculpt

  2. Export the model

  3. Open it in another software (Maya, Blender, etc.)

  4. Import original file and compare

  5. UVs appear vertically flipped

File format used (OBJ, FBX, GLTF, etc.)

OBJ and glTF are fine, only FBX export wrongly flips UVs.
FBX export in 2.8 and before should not be used if there are UVs or textures.
