You don’t need to put the UE4 logo anywhere if you don’t want to. As far as royalties. My understanding is after you make your million dollars, every dollar afterwards is subject to royalties. I think it’s 5% so if you made 1.8 mil you would pay $40,000 in royalties. %5 of 800,000. I don’t know the time frame for the payments or where to send the check to, as of yet I have not made a million dollar game…
