Struct UnitySubMesh 

pub struct UnitySubMesh {
    pub indices: UnityIndices,
    pub material_index: Option<u32>,
}

A single glTF primitive converted to a Unity sub-mesh. Indices are pre-offset to reference the shared vertex array on crate::unity_mesh::UnityMesh.

Fields

indices: UnityIndices

Triangle indices with winding order reversed for Unity’s left-handed convention. Absolute offsets into the parent [UnityMesh::vertices] array.

material_index: Option<u32>

The glTF material index for this sub-mesh, if the primitive referenced one.
