Rewarded Ads Integrations

How can i integrate rewarded video ads to any place of my game i want and how can i reward users . In unity it has thousands of tutorials about it . But in UE4 there is no ad network has support on it . Please someone solve this problem

I added a functional implementation of Chartboost for Android to GetSet’s Chartboost Plugin. You can find the fork here: GitHub - KokkuGames/Chartboost: A plugin for Unreal Engine 4 that integrates the Chartboost SDK.</titl

This also works very well but you have to buy it
