Does that have to do with the new "Electra video system" that apparently is in a test build?
Or is it possible that the animation will be integrated into the game, instead of being separate mp4 files found in the game folder (if you look enough) (go into folder WindowsNoEditor\InHeat\Content\Movies\SexMovies\WIN)
Personally it really turns me of, being able to see the most integral thing outside of the game, without needing to unlock it in any way
Just for anyone else, that path is in the public version...
So go into that folder into game-folder and watch all the sex scenes how much you want without even needing to play the game.
Have fun.
