Cool Stuff! What Do you Think? I'm So Excited!

You have this in the upload section but it looks like you are dong WCIF? What are you excited about? Are you making some mods/objects?
???

Olomaya has a Religion skill/career mod currently up for testing on this page: https://modthesims.info/showthread.php?t=665135

It does include a Peteran religion where you have to attend sermons in a church building (the Mausoleum rabbithole) and an Omiscan religion where you have to interact with divinity objects (sculptures) in order to gain their favors. What you are describing does seem to be covered in the numerous features of this mod, highly recommend you join the testers group! The more, the merrier.

Where can I Find: Maybe. I'm talking about actual mods; Sims have a Religion; Options: Convert Self; Convert Household; Convert Town: Into any Religion; and Celebrating it! With AAncestor alters are easy to come up with without mods though. Another slot for Religion Clothes? God Goddesses walking around?
