Thank you very much, I buy is RealityCapture version 1.0.2.2256 RC Promo usage, why isn’t this option?

It means you have the latest version installed. I cannot see the image you tried to enclose to your last post…
This option (relative pose) becomes visible just after importing a component into your project, and clicking on (selecting) one or more images included in that component in the 1Ds view.
