It is actually, I currently cant find any threads on the forums about it but I know there was one.
Basically modding support is allowed, but preferred only if the people who want to mod the game have ue4 as well.
I am sure an admin will reply with a better answer
What does preffered mean here?
I was planning to focus heavily on modding and make it as easy and intuitive for people. I don’t want to be ‘forcing’ them to get ue4.
