I have seen servers with imersive taming, and this so I believe it works

I'm currently playing it along immersive taming and it works fine. The only thing is that you may want to open Immersive Taming settings and copy-paste the settings from for example the ark's carnotaurus to the mod's one. That way you will need combat taming with rexes and gigantosaurus as it should be.

The only thing i didn't tried is to tame bull variants, argentinosaurus and megalodons. I'll let you know in a future.
