To perform the same result as Blender it requires invert Z.
NodeItem center = get_input_value("Center", NodeItem::Type::Vector3) * val(MaterialX::Vector3(1.0f, 1.0f, -1.0f))

To perform the same result as Blender it requires invert Z. `NodeItem center = get_input_value("Center", NodeItem::Type::Vector3) * val(MaterialX::Vector3(1.0f, 1.0f, -1.0f))`
val(MaterialX::Vector3(1.0f, 1.0f, -1.0f));
