Hi, I want to know, if now, since UE4 is free, if I can ship engine features like static lightmass baking in the shipped product (so it can be done there) which were disallowed yet?
if your asking if you can have a game with the featutres than yes. Just make sure to notify epic. They have a handy post about releasing.
Licensees are not permitted to include UE4 editor or tools features in their game to the public. If you want to include static lightmass baking, you can do so via Epic’s Marketplace or GitHub network, but not to the general public.
