Unity allows specification of texture compression and resolution settings for each platform that the game engine supports, and provides support for bump mapping, reflection mapping, parallax mapping, screen space ambient occlusion (SSAO), dynamic shadows using shadow maps, render-to-texture and full-screen post-processing effects. Unity can import 3D models, animations and sprites from almost any application. Animate characters, objects, sprites, light intensity Create and edit animation clips directly inside Unity. Animate values of any component, material, or script and insert animation events to call script functions at specific times. Move seamlessly between animation states like running and walking with Blend Trees. Exert pinpoint control over the animation playback without the need for complex scripting. One shader provides amazing visual fidelity across high-end mobile, desktop and consoles. Get multithreaded simulation on platforms that support threads.
