I love to do weddings, but they're extremely difficult to set up right. I do them for photo ops so my Simmies can have wedding photos to hang in their new homes. You can't do weddings on a community lot. This is a residential lot I built (the church-no custom content is mine, as I don't know how to do it), and the priest, photographer, bridesmaids, groomsmen and the kids live here. Then I use the InSIMenator to summon in the bride and groom (yeah, I know), use the AddNeighborToFamily cheat so that they're selectable, dress everyone (that takes ages to change makeup, hairstyles, and clothing for everyone), invite my guests to the wedding party and summon in any others I want to attend, then let the wedding take place. Oh, and the priest is "practicing speech" at the podium so it looks like he's talking to the congregation. As for posing the wedding party, that's the good old SnapObjectsToGrid False cheat, and the Boolprop Allow45DegreeAngleOfRotation true cheat. Each of my churches (I have more than one) has a reception hall also on the lot so they can have a reception and photos with the cake.
