In a previous save, my merman, Marcelo, was abducted by aliens and impregnated with an alien life form. According to my game, the alien child is a mer-alien. I decided to speed things up a bit today b...
I was able to fully edit both forms in CAS but be cautious about this since at random the 'normal' form (in this case, both alien/mermaid - i.e. Connor's blue form with tail) can change to the OTHER alien form, which I call the 'true' alien form which is normally uneditable and which often ends up without legs. These two are difficult to maintain which is to be expected as hybrids are unsupported.
You can use these cheats to give yours a tail. It would depend on which ones your hybrid already has (I'm guessing she already has the trait_OccultMermaid trait, but she may not have the other two) traits.equip_trait trait_OccultMermaid_TYAE OR traits.equip_trait trait_OccultMermaid_Discovered after turning testingcheats on of course. In my experience it's always one of these two that are missing and you've just got to equip them and then send her swimming and hopefully she should have a tail. It's always good to be cautious regarding hybrids however.
