Skies and backgrounds with independent coordinate systems for independent translation and rotationz.Seeing through windows into an infinite sky zone in which a sky, planets, mountains, and other objects are constructed.Non-euclidean, redirectable 'warp' portal effects for seeing through teleporters.

Semireflective materials, such as marble surfaces which partially reflect light.Caustic effects such as 'fire waver', 'watery shimmer', and the like can be applied to lights.Radial, cylindrical, spotlight, searchlight, ambient, spherical, shell, and 20+ special effect lights.Supports raytraced and enveloped lighting.with true colored intermixing of fuzzy shadows.32-bit fully colored soft animated dynamic lighting.Internally, Epic used this engine for Unreal and Unreal Tournament. With the level of integration used, some trade-offs were necessary to maintain performance levels with the hardware that was available at the time.įor example, Epic decided to use cylindrical collision detection over the IK collision detection system in an effort to maintain playable framerates on systems that were common at the time of its release. Making its debut in 1998, the first generation Unreal Engine integrated rendering, collision detection, AI, visibility, networking and file system management into one complete engine.
