After struggling for several weeks trying to get a grip on the Unreal Engine, I have decided to abandon this engine for the CryEngine. The main reason for this change is that the Unreal Engine relies on lighting being baked in comparison to the CryEngine which is done in real-time. In addition to that there were several limitation with importing high poly models. The CryEngine allows the importing of higher polycount models to that of the Unreal Engine.
These are some of the renders I did in both engines. I believe the main reason the CryEngine looks better is due to the better handle of textures and realtime lighting. The CryEngine allowed me to maintain the texture integrity without significant degradation by setting the Anisotropic filtering to 16X on the material's textures.
