通过Beast照明系统而集成的烘焙工具,文档”http://unity3d.com/support/documentation/Manual/Lightmapping.html“
自动创建光影图UV(网格导入设置)
地形系统使用相同的解决方案,当使用天光的时候会有全新效果.
已经不必再使用”Lightmapped”着色器;照明系统可以处理出可交互的光影图.以及材质与光影图混合的动态阴影效果.
对象选择器.不再是一个简单的下拉菜单,而是一个新的资源窗口,在这里可以预览关于资源的一些样子和信息.
场景视图的改进,文档”http://unity3d.com/support/documentation/Manual/Using%20The%20Scene%20View.html“.
搜索结果会相应的在场景中高亮显示.

改进相机调整手柄及增加一个相机预览窗口.
改进光源的调整手柄.
将场景导航控制栏风格更统一了.
新的纹理导入设置对话框,更易用的用户界面及各个平台的独立设置.
新的构建设置窗口以更方便的支持多平台发布.
曲线弹出窗口:
有个 AnimationCurve 类型的脚本变量显示在检视面板上为一个曲线字段(curve field).
点击一个曲线字段会打开一个带有曲线的编辑器窗口,类似于动画曲线编辑器那样的窗口.
可定制的曲线字段同样能用在自定义编辑器窗口.
编辑器现在能检查有新版本时候通知用户.
纹理压缩现在为多线程处理,在多核电脑上导入贴图更快.

新的图形功能:
静态遮挡剔除(Occlusion Culling)现在使用Umbra sPVS.
集合体整合(Geometry Batching):原本只在Unity iPhone1.7上的动态和静态的几何体整合功能现在可用于所有平台.
渲染方式:(可以在Player Settings或者每个相机上进行选择;文档”http://unity3d.com/support/documentation/Manual/RenderingPaths.html“)
递延照明(Deferred Lighting).在递延渲染方案中实时灯光数量就不用小心翼翼的用了.照明的消耗仅在它发生作用的像素范围内.所以你可以在场景中用很多小灯泡.
点亮顶点(Vertex Lit).这将使所有着色器和灯光用固定在每个顶点上照明.这个效率很快;主要是在移动平台或者中低端设备上使用.
快速渲染(Forward)照比Unity2.x进行了较大的更改.见下文图形渲染部分.
表面着色器-一个更简单的着色器编写方法.我们没有写关于它的文档,你要相信我们,它真的很易用!
速度上我们优化了渲染代码,相同的场景设置下,比Unity2.6快了20~50%.
用于iOS和Android的OpenGL ES 2.0,你可以给对象用着色器,后期处理效果等等.
Cg/HLSL着色器和Unity3表面着色器将被编译成GLSL后用到场景中.GLSL将被进一步的优化,因为移动平台的技能还不能很好的优化着色器.
当然,由于移动平台还不是十分强大.在可能的情况下你应该使用OpenGL EL 1.1.
Particle Rotation: Particle.rotation, Particle.angularVelocity and respective properties in ParticleEmitter.
Soft Particles! When you use Deferred Lighting and have Soft Particles on in Quality Settings, particles will fade out close to intersections with the scene. All built-in Particle shaders (except VertexLit) support this.
Shadowing improvements: use native shadow maps on Direct3D (faster, less memory, native filtering); much reduced self-shadowing artifacts; Soft shadows support for Point lights; much less “shadow halos” around objects for directional light soft shadows; optimized shadows for Forward rendering path (shares depth buffer with main rendering); optimized shaders for directional light shadows.
Terrain: Added slider (under Terrain Settings) to control detail object density.
Vertex shaders for Shader Model 3.0 on Direct3D9 and GLSL on OpenGL can read from textures.
Skybox is rendered after opaque geometry. Improves performance if your application is fillrate bound.
Separate Alpha Blending: use Blend ColorSrc ColorDest, AlphaSrc AlphaDest in ShaderLab.
In-editor visualization on which objects would use which rendering paths (green/yellow/red for deferred/forward/vertexlit).
#pragma glsl for compiling Cg/HLSL shaders into GLSL instead of ARB assembly programs on OpenGL.
Compiling shaders to #pragma target 3.0 allows 512 texture indirections on OpenGL (up from 4).
Development standalone players on Windows have Direct3D PIX events; useful if you use PIX, Intel GPA or other graphics performance tools.
Fog just works on Direct3D with Shader Model 3.0 shaders, on OpenGL with GLSL and on OpenGL ES 2.0. Additionally, there’s no need to write #pragma fragmentoption ARB_fog_exp2 in your shaders anymore; just remove that line.
CameraDepthTexture modes can be combined if you want to get both depth & depth+normals textures.
It is possible to forcibly disable Anisotropic filtering on a texture, even when Quality Settings have anisotropic on all textures. Just set anisotropic slider on the texture to zero.
Uniformly scaled objects will no longer be pre-scaled before rendering – instead uniform scale is now natively supported by the renderer.
Cg/HLSL VPOS (pixel position) pixel shader input semantic is supported now.
Terrain: Expose detail resolution per patch; previously was hardcoded to 8.
Terrain: Improved performance of painting textures & detail objects.
Asset Pipeline Improvements:
Upgraded to FBX SDK 2011.2.
Import support for stepped and linear keys for position curves; improved compression and curve fitting for position curves.
Settings for allowed animation compression error in mesh importer.
Implemented support for importing 1 unit in 3dsmax as 1 unit in Unity (the default is 1 cm in 3dsmax as 1 unit in Unity).
Implemented import of tangent space from FBX, .max, .mb and .ma files.
Switched Cinema4D import process to work in background mode.
Support for Cinema4D R11 on Mac OS X.
Support for FBX2010 format when exporting from Cinema4D.
Audio Improvements:
Filter components: Reverb, Echo, Distortion, Chorus, High- and Low-pass. Can be applied to each audio source or globally to the listener.
Reverb Zones: Apply reverb to main audio output, when the listener is within zone(s) defined by a position and min/max radii.
Live output and spectrum data access from each audio source or globally from the listener.
Tracker/Mod file support.
Sample-accurate synching. Sources played in the same frame are always started at the exact same point in time. Sources can be delayed and played in the future on an exact sample accurate boundary with .Play(int64 delay).
Surround sound (7.1, 5.1, 4.0, ProLogic DTS) support.
Attenuation curves for volume, spread, panning and lowpass filter factors.
Doppler factor per audio source.
AudioSource prioritization.
iOS latency settings. Choose between Default, Best Performance, Good Latency and Best Latency.
Asset memory is freed after loading audio data.
Physics Improvements:
Upgraded PhysX to 2.8.3.
Cloth and clothing simulation: use the new InteractiveCloth, SkinnedCloth and ClothRenderer components.
Layer based ignore collisions: use the Physics inspector or Physics.IgnoreCollision().
Continuous collision detection, to make sure that fast moving colliders will not pass through other colliders. See Collider.collisionDetectionMode.
Added Physics.SphereCast() and Physics.CapsuleCast() to implement volume raycasts.
Added Rigidbody.SweepTest() to check if a Rigidbody would collide with anything if moved into a certain direction.
New Scripting Features (documentation):
Mono Develop for script editing and debugging! Documentation.
Upgrade Mono and C# compiler to Mono 2.6.3. This brings C# 3.5, variable type inference, lambda e­xpressions, LINQ and more.
New UnityScript compiler: generics, interfaces, structs, type cast operator, anonymous functions/closures, lambda e­xpressions, function types, type inferred array comprehensions and more.
New Boo compiler.
Mono class libraries derived from Silverlight profile for the web player.
Socket security sandbox implementation. Just like Flash (think crossdomain.xml).
WWW class security sandbox implementation. Just like Flash (think crossdomain.xml).
Per-platform script defines. Use UNITY_EDITOR, UNITY_WEBPLAYER, UNITY_IPHONE etc. Documentation.
Improved UnityScript compilation speed.
New scripting API functions (documentation). Some highlights:
WWW.responseHeaders will contain the response headers received from the HTTP server.
Application.isWebPlayer.
SystemInfo.graphicsPixelFillrate to query GPU pixel fillrate. Returns fillrate for about a thousand GPUs out there.
GL.ClearWithSkybox.
Math functions: MoveTowards to Mathf, Vector2, Vector3, and Vector4; Quaternion.RotateTowards.
Changed Mathf.Approximately to not only be useful for comparing very small numbers.
Stacktraces have been prettified, useless information is better stripped from stack traces.
Other Improvements:
Web Player: Java and ClickOnce based installer on Windows for true one-click installation process.
IME input support (for languages like Japanese, which require multiple keypresses to enter a character) on Windows, and in the editor and standalone on the Mac.
Support for OS font rendering (new “dynamic” font rendering mode), to save space in distribution and texture sizes. Textures are generated dynamically to contain the characters which are needed.
Documentation: scripting examples in UnityScript; C# and Boo. Docs for all platforms merged and platform specific parts toggle-able.
Web Player: UnityObject.js script makes Web Player embedding easier.
iOS: Added cpu-waits-gpu metric in internal profiler; useful for tracking down GPU bound applications.

Networking: Connection tester, Network.TestConnection(), now reports your NAT implementation type more accurately.
Networking: Exposed Network.logLevel so you can change the amount of log output at runtime.
Networking: Added network GUID, used for NAT punchthrough.
Bug Reporter: Supports multiple file attachments; trims attached log files if they are too large.
Some Changes We Did
We thought you might want to know about them… Read more in the docs.

Graphics Changes:
Forward rendering path had lots of changes:
Most common case (one directional per-pixel light) is drawn in one pass now! (used to be two passes in 2.x)
Point & Spot light shadows are not supported. Only one Directional light can cast shadows. Use Deferred Lighting path if you need more shadows.
Most “Vertex” lights replaced with Spherical Harmonics lighting.
Forward rendering path is purely shader based now, so it works on OpenGL ES 2.0, Xbox 360, PS3 (i.e. platforms that don’t support fixed function rendering).
Shader & ShaderLab changes:
If you want to write shaders that fully interact with lighting; it’s best to use Surface Shaders.
Unity 2.x per-pixel lit shaders will need to be manually converted to surface shaders or manually fixed.
Shaders are compiled to more targets by default (e.g. OpenGL ES 2.0); you might hit some places where OpenGL ES 2.0 does not like some Cg/HLSL constructs. Either fix the offending places, or exclude shader from OpenGL ES 2.0 via #pragma exclude_renderers gles.
Lots of sanitization to built-in variable names (mostly to accommodate new OpenGL ES 2.0, Xbox 360, PS3 platforms).
Unity 3.0 will automatically upgrade most of 2.x shaders for syntax changes. This actually modifies your shader files (look for “Upgrade NOTE” in your files).
Normal map compression; just mark texture as Normal Map and will be DXT5nm compressed at decent quality. All shaders need to use UnpackNormal(n) instead of n*2-1.
Remove concept of “RECT” textures. All non-power-of-two RenderTextures are addressed with 0..1 UVs now (just like in D3D9 in Unity 2.x).
Parallax shaders get height from a separate texture now.
Self-Illuminated shaders get illumination from a separate texture now.
Terrain lighting modes (Vertex/Lightmap/Pixel) are gone. Terrain is lit just like everything else now.
When rendering with Shader Replacement, no lighting is ever applied. Skybox, GUI, Halos, Projectors are not rendered.
Background shader queue is treated like Geometry now (arbitrary sorting, assumed to be opaque).
OnBecameVisible/OnBecameInvisible have slight behaviour changes. For example, now they are not called each frame on a shadow caster that is not visible itself.
Self-Illuminated materials calculate emissive color as (material color * texture * illumination); previously was (texture * illumination).
Simplified Shadow Bias setting on Lights.
Depth render textures on D3D9 use native depth buffer. Value distribution changed from linear to z-buffer like (just like in OpenGL).
Spot lights attenuate exactly like Point lights now.
Point lights with Cookies actually attenuate now.
OnRenderObject script callback behaviour changed. Now those callbacks are called after everything is rendered; not at points in the middle of rendering.
Changed the way the Camera-DepthTexture and Camera-DepthNormalTexture shaders are loaded so that they can be overridden when needed.
Custom Tree shaders specify their billboard shader via Dependency keyword now (instead of Tag). The billboard shader will be automatically included in the build.
Screen space coordinates should use float4 on all platforms (used to be V2F_SCREEN_TYPE). When sampling a texture with tex2Dproj, use UNITY_PROJ_COORD macro around it.
Added WorldSpaceViewDir() and WorldSpaceLightDir() functions to UnityCG.cginc.
Obscure Graphics Changes That No One Will Probably Notice TM: documentation.
Renamed the 2.x tree shaders and the 3.x Tree Creator shaders; both are put under “Nature” section.
OnPreCull, OnPreRender, OnPostRender and OnWillRenderObject messages are not sent to disabled behaviors.
Old Unity 2.x Lightmapped shaders moved under “Legacy Shaders” submenu.
Terrain: Removed the concept of grayscale lighting from terrains.
Editor Changes:
Unity Editor on Mac OS X requires Intel-based Mac and OS X 10.5 “Leopard” or later.
Removed Soft Vegetation option from Quality Settings UI. It does nothing in built-in shaders now.
Separated preferences for 3.x and 2.x editors.
Removed ancient Dinosaur graphics emulation.
Moved “All compile errors must be fixed” notification to scene view notifications (moved it out of console).
Made the curve editor send a CurveChangeCompleted event when the curve change has been completed.
Create New Project dialog now expects user to select an existing, empty folder on the Mac
Mesh Import option “Split Tangents” is on by default.
Texture Importer:
Bump maps are now referred to as “normal maps” in the editor.
Normal maps are labelled as “NM” in their format.
PVRTC compression level moved to advanced settings.
Generating a Cubemap will make the cubemap be the root asset.
Textures that only use one value across the whole alpha channel and that value is not 1 are marked as needing-alpha-channel.
The command and control key modifiers in the view tool have been switched on OS X. Now command moves and control zooms. Control still moves on Windows.
Physics Changes:
Rigidbody mass is no now longer limited to 10000.
RaycastCollider is now deprecated.
Center of gravity and inertia will now always be automatically recalculated when setting or animating collider properties or positions, unless they had been explicitly set from code before.
Slope limit on character controller now works properly above 45 degrees. When loading old scenes the value will be clamped to 45 degrees to mimic the old behaviour.
JointDrive.maximumForce will now also be taken into consideration when JointDrive.mode is JointDriveMode.Position. You may need to change your joint setups so that they still work.
Unity iOS Changes:
iPhoneStreamingAssets is renamed to StreamingAssets and is now located under the Assets folder (visible from within the Editor).
Target iOS Version field added to player settings. Now deployment target can be specified separately from active SDK version.
“Enable Unity Networking” flag removed from iOS player settings. Now stripping of networking is handled automatically.
Most iPhoneInput members moved to Input class.
Native plugin support added to both Basic and Advanced Unity iOS licenses.
Added support for iPad / iPhone Simulator
Hardware audio decoder is now shared between audio clips.
Other Changes:
Random number generator (Random class) was changed. It is marginally slower, but produces better “randomness”, especially in lower bits. Additionally, integer version is not limited to 15 bits range.
Internal Random number generators (for Particles etc.) are reset after each level load. Now your particles in any level do not depend on what levels were loaded before.
The default runtime font is now Arial 13, as rendered as a dynamic font on Mac OS X and Windows.
Scripting: Renamed WWW.data to WWW.text
Scripting: ScriptableObject derived classes must be instantiated using one of ScriptableObject.CreateInstance overloads.
Scripting: UnityScript strict mode no longer allows arbitrary downcasts from Object (unless #pragma downcast is used).
Input: Keyboard on MacOS X will now reflect the behavior on Windows (two separate KeyDown events for key code and character, KeyUp event only for key code).
Scripting: Removed support for .NET 1.1 profile.
Scripting: Made previously undocumented GUIClip class internal to UnityEditor.
Networking: Connection tester now requires 4 public IP addresses to work.

Web Player: Several fixes to make it work better with Google Chrome on Mac OS X.
Known Issues
MonoDevelop: Single-stepping outside the control flow of a script while debugging results in decreased performance until normal execution continues.
A flaw in the way 64 bit Windows OS handle structured exceptions for 32 bit applications can cause crashes in Unity players. The issue may surface, for example, if a player running on a 64 bit Windows causes a NullReferenceException to be thrown, even if the exception is handled. This bug affects all 32 bit applications running on 64 bit Windows, including Microsoft .NET applications.
A hotfix solving the issue is available on support.microsoft.com, but of course this does not help your end user. Your best bet is to keep your players exception-free (which is always a good idea), at least until the fix is distributed to end users via Windows update.
Touch.deltaPosition and Touch.deltaTime can be inaccurate on Android.
Tree Editor Leaves can not be manually rotated.
Debugger: Does not halt on some exceptions thrown from internal Unity engine code.
Build Settings Window may not initially react to mouse clicks. Workaround: move/resize the window.
Generate Lightmap UVs: the results may be different on mac and windows. If you encounter this problem, please report a bug.
Generate Lightmap UVs: performance degradation is expected on highly tessellated mesh. This will be fixed in subsequent releases.
Graphics: Anti-Aliasing does not work with Deferred Lighting.
