using the cheat console and entering, e.g., 'riv_rel Bob Pancakes Iggy Pancakes'.using the friendly interaction 'Ask if Sim is related', or.gedcom files to keep genealogical information even if sims are culled.
This mod in one long sentence: riv_rel calculates and puts the exact bio/in-law relation between two sims into words, adds a friendly interaction to ask a sim exactly what their relation to your sim is, adds a bunch of console commands (enter riv_help to list this in game), adds options for additional incest prevention, and you can create external. please consider this broken riv_rel - last updated (gen 7) Thank you all so so much for your support and I'm sorry for my silence - I'm unlikely to ever go back to sims 4 for anything other than CAS and my job has taken all my programming energy.
