We had been working with Unreal Engine 4, which has lots of incredible features and excellent rendering quality, but some of the things we wanted to do were more complex, or would have required us to branch the source code of Unreal to basically make our own version. Unigine 2 is much more low level and thus provides us more flexibility and computational power. Unigine 2 is perhaps less developed than Unreal regarding the game engine side (level edition, assets integration, etc, even if this is progressing rapidly and should improve in the near future), but as we generate everything procedurally those features are less relevant for us.
However, the freedom in low level modification and the clear focus of Unigine 2 towards large scale open world rendering was a perfect match for us. It also gives us a great platform to develop our own PBR (Physically Based Rendering) shading framework. We have already started to work with our engineers on many other rendering technologies on top of Unigine 2 features, that will enable us to provide really cool stuffs visually.
