Description:

When exporting a mirrored object from Nomad Sculpt in GLTF or OBJ format, the split normals are incorrectly oriented inward. This issue does not occur with non-mirrored objects and results in shading artifacts when the model is viewed in other software such as Blender.

Steps to Reproduce:

  1. Create a new project in Nomad Sculpt.
  2. Mirror an object within the project.
  3. Export the mirrored object as a GLTF or OBJ file.
  4. Open the exported file in a 3D modeling software (e.g., Blender) and observe the split normals.

Please fix.
