本软件是由unity机构出品的Unity游戏开发引擎软件V5.3.3F1版，UNITY PRO V5.3.3F1 WIN64，大小：250 MB，支持Win64位系统，语言：英语。

Unity是由Unity Technologies开发的一个让玩家轻松创建诸如三维视频游戏、建筑可视化、实时三维动画等类型互动内容的多平台的综合型游戏开发工具，是一个全面整合的专业游戏引擎。Unity类似于Director,Blender game engine, Virtools 或 Torque Game Builder等利用交互的图型化开发环境为首要方式的软件其编辑器运行在Windows 和Mac OS X下，可发布游戏至Windows、Mac、Wii、iPhone、Windows phone 8和Android平台。也可以利用Unity web player插件发布网页游戏，支持Mac和Windows的网页浏览。它的网页播放器也被Mac widgets所支持。

Unity3D是一个让你轻松创作的多平台的游戏开发工具，是一个全面整合的专业游戏引擎，从一开始就被设计成易于使用的产品。作为一个完全集成的专业级应用，Unity还包含了价值数百万美元的功能强大的游戏引擎。Unity 4作为一个游戏开发工具，它的设计主旨就是让你能够创建令人惊讶的游戏。如果你之前尝试过Unity，请查看Unity 3都做了哪些更新。如果你是第一次尝试，那就好好看看吧，看Unity都能为你带来什么。Unity作为一种开发环境，可让你脱离传统的游戏开发方式，以一种更简单的方式专注于你的游戏开发。开发网络游戏、移动游戏、单机游戏，Unity都能完全胜任。

UNITY PRO V5.3.3F1 WIN64

Unity – a multiplatform tool for game development, from the very beginning created to facilitate your creativity. Unity provides a comprehensive set of professional quality applications, and “quite accidentally” contains the most powerful engine this side of a million dollars.

Graphics features:

Shader importing has been massively improved:

• Shaders are imported much faster, especially complex surface shaders. Instead of compiling all shader variants for all possible platforms at import time, now the needed shader variants for needed platforms are compiled on-demand. Shader compilation results are cached under Library folder, so identical compilations happen much faster.

• Error reporting was improved. Errors are reported on correct lines (imagine that!), and errors in .cginc files report the filename.

• Surface shader debugging was improved. No more “#pragma debug” nonsense; just click “Show generated code” in the inspector.

• Added Sparse Texture support (also known as “mega textures” or “tiled textures”). This is a low-level API feature, see SparseTexture class. Implemented on DirectX 11.2 (via tiled resources) and desktop OpenGL (via ARB_sparse_texture).

• Added stereoscopic rendering on DX 11.1 (requires Windows 8.1 and compatible hardware).

• Introduced support for OpenGL ES 3.0 on iOS devices (starting with A7 devices).

• Graphics: Support for 3D textures in OpenGL ES 3.0.

OS – Windows XP, Windows Vista, Windows 7, Windows 8
