Detailed Documentation¶

Editor-only helper that serializes a Mesh to Wavefront OBJ text.

Coordinate convention: Unity is left-handed (Y-up, +Z forward), while most OBJ consumers (Blender, Maya, etc.) expect a right-handed space. To keep exported geometry both upright and correctly-facing we flip the X axis and reverse triangle winding :

• Vertex: v = (-x, y, z)

• Normal: vn = (-nx, ny, nz)

• Faces: triangle indices are emitted in reversed order (a, c, b) so faces stay outward-facing after the axis flip.

Only attributes present on the mesh are emitted (positions always; UV channel 0 and normals only when populated). Vertices are exported in local space as-is. Floats are formatted with CultureInfo.InvariantCulture so the decimal separator is always ‘.’ regardless of the machine locale.
