You can breed them with S+ mutator (they will gestate if you use the allow breeding as they cant lay eggs)

I want them to be breedable as well, since S+ mutator's radiation pulse doesnt work on domination rex when you use the allow breeding pulse. It makes super breeding them much longer

Well, I'm trying to breed with them using the S+ mutator. But no gestation. Just a reset of the breeding timer. I haven't touched the ini files so unless they are auto-excluded somehow I have no clue what is going on.

First trigger the "allow breeding" pulse on S+ mutator, and then switch the domrexes to "enable mating" did the trick :D

S+ and Best Eggs mod...

They will lay eggs like regular dinos.

is there a way for i can change setting to allow breeding the indom
