Struct FbxTangentSet 

pub struct FbxTangentSet {
    pub layer: FbxLayerSet<4>,
    pub has_handedness: bool,
}

Available on crate features fbx-reader or fbx-writer only.

A preserved FBX LayerElementTangent or LayerElementBinormal.

FBX splits these across two sibling arrays: Tangents holds three components and the handedness sign lives in a separate TangentsW, which only FBX 7500 and later write. They are merged into one four-component value here because that is the form glTF’s TANGENT needs, and split again on write.

Fields

layer: FbxLayerSet<4>

Tangent vectors, with the handedness sign in w.

has_handedness: bool

Whether the source carried an explicit handedness array.

When it did not, w was defaulted to +1.0. The writer emits the sibling array only when this is set, so a document that had no handedness does not gain one by being rewritten.
