Unreal engine 4 for animated 3D movies does not pay any royalties ... Right?

My basic idea is to do modeling and animation in Blender and then render it in UE4. I understand that if I make an animation with UE4 I do not have to pay anything to Epic in terms of royalties and anything else.

I would like a moderator or someone with years working on this engine to confirm if it is true and if in some future EPIC GAMES modify the EULA and the Animations will also have to pay royalties.
The truth is that I would not like to have legal problems with EPIC GAMES (Tencent). regards
