I want to align two separate components (not merge them)

Hi all, looking to get some insight… So basically I have two data sets, one non and one cross-polarized. My goal is to extract the roughness map. So my thoughts are I want to align two separate components (not merge them.) Seems like a straightforward enough thing to solve however I’m not having any luck figuring it out. Is this possible? I’m wondering if someone has done this or would have any insight as to how this could be done all within in RealityScan. Any insight would be appreciated! Thanks!
