Alphas and Omegas with high enough romantic relationships will have the option to Mate (woohoo).
Sims can have multiple mates. However there is no anti-jealousy functionality included with Omegaverse.
Should you wish to play with multiple mates, it is recommended that you use MC Command Centre’s or Wicked Whim’s anti-jealousy capabilities.
Mating will quickly lead to a heat/ rut for Alphas and Omegas, if they are not already in heat/ rut.
Mated sims will only lust after their mate(s) during their heat/ rut, rather than any Alpha/Omega in the vicinity. In the strongest phases of their heat/ rut, a mated Alpha/ Omega may be turned on by a nearby Omega, but otherwise they only wish to be with their mate.
Unmated sims will feel guilty about lusting after a mated sim.
Mated Betas will notice when their mate is in heat/ rut.
Sims who are mated will suffer from Separation Sickness if they spend too long away from their mate. Separation sickness starts off with the sim simply missing their mate. If allowed to decay completely, the sims’ mating will lapse and they will lose all of their mates.
For Omegas, if their separation sickness is allowed to decay fully, they will die.
Sims can spend roughly four days apart before feeling the effects of separation sickness, they then have another day to rectify this before the full consequences take effect. This time is slightly more for Alphas, and slightly more for Omegas
Separation sickness is rectified by spending time in a sim’s mate’s company, with the “Near Mate” buff active (or equivalent heat/ rut buff).For every 10 minutes mates spend together, they can spend an additional 25 minutes apart.
Mates can also “reaffirm” their mating, in order to reset their separation timers back to maximum.
Separation Sickness can be changed between Easy and Hard mode for individual sims (default: Easy Mode). On hard mode, sims can only spend roughly two days apart before the effects of separation sickness begin to take hold.
Scared Mated Omegas have a chance of being comforted just by their Mated Alphas presence.
Scared, stressed, sad & angry mated Omegas will affect their mated Alpha's mood and give them a negative moodlet based on the emotion the Omega is feeling. Alphas will have an interaction to comfort their Omega and make them feel better.
VFX during rut.
Omegas will show a bite mark on their neck after being mated.
Fated mates from Werewolves is also available to ABO sims.
