资产管理 (Asset Management)

Workflow with Digital Content Creation (DCC) tools

数字内容创建(DCC)工具的工作流程

FBX Importer/Exporter: Unity and Autodesk are directly collaborating to bring you the best FBX support in the industry. We are working to make your content creation and interactive workflow pipelines as efficient and effective as possible. This collaboration has enabled Unity to work directly on FBX SDK source code making improvements to the Unity FBX importer and exporter and a custom Unity plugin for Maya. All in all, it has resulted in a powerful round-trip workflow.

FBX导入器/导出器： Unity和Autodesk直接合作，为您提供业界最佳的FBX支持。 我们正在努力使您的内容创建和交互式工作流管道尽可能高效。 这项 合作 使Unity可以直接在FBX SDK源代码上工作，从而改进了Unity FBX导入器和导出器以及用于Maya的自定义Unity插件。 总而言之，它带来了强大的往返工作流程。

The new Unity FBX Exporter adds the ability to export FBX geometry for use outside of Unity.  In particular, the improvements in FBX support allow you to send your work to Maya/Max and then non-destructively merge changes back into your Unity Asset.  The exporter also provides support for materials and textures, and GameObject components including colliders, rigid body, scripts, and audio, etc

新的Unity FBX导出器增加了导出FBX几何体以便在Unity外部使用的功能。 特别是，FBX支持方面的改进使您可以将工作发送到Maya / Max，然后以无损方式将更改合并回Unity资产。 导出器还提供对材质和纹理以及GameObject组件的支持，包括对撞机，刚体，脚本和音频等。

Exporting from Maya to Unity is now simpler and more complete than ever thanks to the Unity custom Maya exporter plugin.  With one click in Maya, you can export FBX files, including materials, textures, and Stingray Physically-Based Shaders, with maximum fidelity for use in  Unity.

现在有了Unity自定义Maya导出器插件，从Maya到Unity的导出比以往任何时候都更加简单和完整。 在Maya中单击一下即可导出FBX文件，包括材质，纹理和基于物理的Stingray着色器，并在Unity中使用时具有最大的保真度。

The improved Unity FBX importer provides support for hierarchies, materials, textures, Stingray PB shaders, and animated custom properties (when present in the FBX file).  With these improvements, work done in Unity is preserved and updated Maya assets slot right back into your Unity scene, so you can simply pick up where you left off and continue your work.

改进后的Unity FBX导入器支持层次结构，材质，纹理，Stingray PB着色器和动画自定义属性(在FBX文件中存在时)。 有了这些改进，就可以保留在Unity中完成的工作并将更新的Maya资产插槽重新放回到Unity场景中，因此您可以简单地从上次中断的地方继续工作。

The FBX Exporter package (in beta) is available from the Unity Asset store, and includes the custom Maya plug-in.

FBX Exporter软件包(测试版)可从 Unity Asset商店获得 ，并包括自定义Maya插件。

Embedded materials on import

进口嵌入式材料

Now you can create materials inside the import prefab instead of in an external ‘Materials’ folder. FBX files may contain embedded textures and materials. Until recently, the first import always created additional assets. However, subsequent imports did not create additional assets, unless the generated materials had been moved or deleted. Textures were overwritten on every import. We have added the option of making embedded materials appear inside the FBX in the project, and made them read-only. You can also manually extract textures via a button in the import inspector. Finally, extracting an FBX file into the project creates an editable clone. This clone is explicitly associated with the original FBX meshes via the importer’s metadata.

现在，您可以在导入预制件中而不是在外部“材料”文件夹中创建材料。 FBX文件可能包含嵌入的纹理和材料。 直到最近，第一次导入始终会创建其他资产。 但是，除非将生成的材料转移或删除，否则后续的进口都不会创建其他资产。 每次导入都会覆盖纹理。 我们添加了使嵌入材料显示在项目中的FBX中的选项，并将其设置为只读。 您也可以通过导入检查器中的按钮手动提取纹理。 最后，将FBX文件提取到项目中将创建可编辑的克隆。 该克隆通过导入程序的元数据与原始FBX网格明确关联。

Animated Custom Properties

动画自定义属性

Various DCCs (e.g. Maya and 3DSMax) support adding custom properties (or attributes) to objects:

各种DCC(例如Maya和3DSMax)支持向对象添加自定义属性(或属性)：

Unity can now import animation curves on custom properties from FBX files (disabled by default):

现在，Unity可以从FBX文件导入自定义属性的动画曲线(默认情况下禁用)：

These will appear in the Animation Window as Animator properties, just like additional curves created from imported clips:

这些将显示为“动画”窗口中的“动画”属性，就像 从导入的剪辑创建的其他曲线 一样 ：

You can then use a MonoBehaviour to drive other Component properties, or use an AssetPostprocessor to bind your curves directly to any Component.

然后，您可以使用MonoBehaviour驱动其他Component属性，或使用AssetPostprocessor将曲线直接绑定到任何Component。

Maya/3DSMax Stingray physically based shader

Maya / 3DSMax Stingray物理着色器

Importing FBX files containing models using the Stingray PBS shader is now supported:

现在支持使用Stingray PBS着色器导入包含模型的FBX文件：

Stingray PBS Materials in Maya 2016:

2016年Maya的Stingray PBS材料：

Same materials imported in Unity:

在Unity中导入的相同材料：

Notes:

笔记：

• The Stingray PBS has slightly different properties than the Unity Standard Shader, so we have created a shader variant called “Standard (Roughness setup).” This shader has a separate roughness map, and thus consumes more graphics resources than the Unity Standard Shader. For this reason, this shader requires shader model 3.5 in forward rendering. We recommend using the Standard shader where possible.

  Stingray PBS的属性与Unity Standard Shader略有不同，因此我们创建了一个名为“ Standard(粗糙度设置)”的着色器变体。 该着色器具有单独的粗糙度图，因此比Unity Standard着色器消耗更多的图形资源。 因此，此着色器在正向渲染中需要着色器模型3.5。 我们建议尽可能使用标准着色器。

• The Stingray PBS and Unity Standard Shaders have similar looks and responses to light, but do not use the same code. There will be differences between what you see in Maya or 3DSMax and what you see in Unity.

  Stingray PBS和Unity标准着色器具有相似的外观和对光的响应，但是没有使用相同的代码。 在Maya或3DSMax中看到的内容与在Unity中看到的内容之间会有差异。

• Any changes made to the underlying ShaderFX graph in Maya or Max are not exported in the FBX file and thus will not be reflected in Unity. We do not recommend modifying the ShaderFX graph.

  在Maya或Max中对基础ShaderFX图形所做的任何更改都不会导出到FBX文件中，因此不会反映在Unity中。 我们不建议修改ShaderFX图形。

Improvements to Avatar Masks

阿凡达面具的改进

In 2017.2, the workflow and UI for mask updates has been improved by displaying the updated hierarchy, with the invalid mask paths in red. Mask checkboxes for invalid paths are disabled.

在2017.2中，通过显示更新的层次结构(红色的无效蒙版路径)改进了蒙版更新的工作流和UI。 无效路径的掩码复选框被禁用。

New AssetBundle API for more control

新的AssetBundle API可实现更多控制

AssetBundles lets you segment your app into multiple files, and call upon them when you need them, whether they’re local or remote.  This is great for optimizing performance or managing how your app files are distributed. Shipping with 2017.2 is a brand new API for AssetBundles.  If you use AssetBundles to pull in content securely from a CDN, this could be for you.   Previously, your options  for loading  AssetBundles were either from File or Memory.  Sometimes, however, an intermediary step needs to be taken before the data is usable.  For example, we wanted to solve the issue where a client is pulls data from a secure CDN.  In this case, decrypted content would be served as a stream, and you’d have to write extra steps to convert the data to a useable format.  Now, you can read the data directly as a managed Stream object with a new API, AssetBundle.LoadFromStream.  And less code is required from you!

通过AssetBundles，您可以将应用划分为多个文件，并在需要时调用它们，无论它们是本地文件还是远程文件。 这对于优化性能或管理应用程序文件的分发方式非常有用。 2017.2附带的是AssetBundles的全新API。 如果您使用AssetBundles从CDN安全地引入内容，则可能适合您。 以前，用于加载AssetBundle的选项来自文件或内存。 但是，有时在数据可用之前需要采取中间步骤。 例如，我们要解决客户端从安全CDN提取数据的问题。 在这种情况下，解密的内容将作为流提供，并且您必须编写额外的步骤才能将数据转换为可用格式。 现在，您可以使用新的API AssetBundle.LoadFromStream作为托管Stream对象直接读取数据。 您所需的代码更少！

OpenVR support for MacOS

对MacOS的OpenVR支持

Unity has worked closely with Apple and Valve to optimize Metal 2 to run against Unity’s current VR rendering paths, Multi-Pass, and variants of Single-Pass. For the final release, developers will be able to improve performance using the new Metal 2 features announced at WWDC and combining them with the use of instancing. This will cut the number of draw calls required in half.

Unity与Apple和Valve紧密合作，优化了Metal 2，使其能够与Unity当前的VR渲染路径，Multi-Pass和Single-Pass的变体兼容。 对于最终版本，开发人员将能够使用WWDC上宣布的新Metal 2功能，并将其与实例化结合使用来提高性能。 这样可以将所需的绘图调用次数减少一半。

Stereo Instancing (PC)

立体声实例化(PC)

Stereo Instancing (also known as single-pass instanced rendering) is an evolution of Unity’s single-pass rendering and is now supported when building with DX11, allowing developers to greatly optimize performance for Vive, Oculus Rift, and Windows Mixed Reality immersive headsets.

立体声实例化(也称为 单遍实例 渲染)是Unity单遍渲染的演进，现在使用DX11进行支持。开发人员可以极大地优化Vive，Oculus Rift和Windows Mixed Reality沉浸式耳机的性能。

The biggest impact of using this technique is that you can dramatically reduce (half, at times) the number of draw calls generated on the API side, saving a good chunk of CPU time.  Additionally, the GPU itself is able to more efficiently process the draws (even though the same amount of work is being generated). Note: Stereo Instancing is only supported with forward rendering.

使用此技术的最大影响是，您可以显着减少(有时是一半)在API端生成的绘制调用的次数，从而节省了大量CPU时间。 此外，GPU本身能够更有效地处理绘图(即使正在生成相同数量的工作)。 注意：仅向前渲染支持立体声实例化。

To enable this feature, open Player Settings (menu: Edit > Project Settings > Player). In Player Settings, navigate to XR Settings, ensure the Virtual Reality Supported checkbox is ticked, then tick the Single-Pass Stereo Rendering checkbox. Note that stereo instancing only works with Windows 10; you can find more information here.

要启用此功能，请打开“播放器设置”(菜单：“编辑”>“项目设置”>“播放器”)。 在“播放器设置”中，导航到“ XR设置”，确保选中“支持虚拟现实”复选框，然后选中“单通道立体声渲染”复选框。 请注意，立体声实例化仅适用于Windows 10。 您可以 在此处 找到更多信息 。

Editor Simulation for Vive HMD

Vive HMD的编辑器仿真

This new feature allows certain aspects of the Vive HMD to be simulated in the Editor, without the need of a physical HMD. This is enabled by adding “Mock HMD‒Vive” to the Virtual Reality SDKs in Player Settings > XR Settings.

这项新功能允许在编辑器中模拟Vive HMD的某些方面，而无需物理HMD。 通过在“播放器设置”>“ XR设置”中的“虚拟现实SDK”中添加“模拟HMD‒Vive”来启用此功能。

The mock HMD will use the same asymmetric projection matrix, hidden occlusion mesh, field of view, aspect ratio, and eye texture size as the Vive. Mock HMD can be used with both multiple and single-pass rendering paths, and it will render as a split screen stereo display in Editor.

模拟HMD将使用与Vive相同的非对称投影矩阵，隐藏的遮挡网格，视场，纵横比和眼睛纹理大小。 模拟HMD可以用于多遍和单遍渲染路径，它将在编辑器中渲染为分屏立体显示。

其他平台改进和更新 (Other Platform Improvements & Updates)

Other improvements include Native Rendering Plugin support for Nintendo Switch, which enables you to implement low-level rendering and work with Unity’s multi-threaded rendering.

其他改进包括对Nintendo Switch的本机渲染插件的支持，它使您能够实现低级渲染并与Unity的多线程渲染一起使用。

macOS player Retina support

macOS Player视网膜支持

We’ve added support for targeting Retina resolutions for macOS on devices that support it.

我们增加了对在支持macOS的MacOS上针对Retina分辨率的支持。

Windows Player Launcher

Windows Player启动器

We’ve moved the majority of the Windows Standalone Player into a separate signed DLL (“UnityPlayer.dll”), leaving the executable to be a thin wrapper that just calls into it.

我们已经将大多数Windows Standalone Player移到了单独的签名DLL(“ UnityPlayer.dll”)中，而该可执行文件只是一个调用它的精简包装。

图形 (Graphics)

GI Profiler

GI探查器

The addition of the GI profiler shows relevant statistics, including how much CPU time is consumed by the Realtime Global Illumination subsystem to help you optimize GI in your scenes.

GI探查器的添加显示了相关的统计信息，包括实时全局照明子系统消耗了多少CPU时间以帮助您优化场景中的GI。

HDR Emission

HDR排放

Global Illumination emission now uses 16-bit floating point format for both realtime and baked GI. The HDR color picker limit increased from 99 to 64k to unlock the full range. This makes it possible to emit much stronger light from emissive surfaces.

现在，全局照明发射针对实时和烘焙GI使用16位浮点格式。 HDR颜色选择器的限制从99k增加到64k，以解锁整个范围。 这使得可以从发射表面发射更强的光。

Lightmap background (push-pull dilation)

光照贴图背景(推拉膨胀)

The feature fills the empty areas in the lightmaps with content from lower MIP levels (push-pull dilation). This will fix the cases where dark pixels around geometry edges are visible when rendering with lightmaps. This is due to dark background texels bleeding in when lower MIPs are accessed.

该功能将MIP级别较低的内容(推拉膨胀)填充在光照图中的空白区域。 这将修复在使用光照贴图进行渲染时可见几何边缘周围的暗像素的情况。 这是由于访问较低的MIP时背景暗纹理会渗色。

Progressive Lightmapper Improvements

渐进式光照贴图程序改进

We now support double-sided materials in the Progressive Lightmapper. We’ve added a new material setting that causes lightning to interact with backfaces. When enabled, both sides of the geometry are accounted for when calculating Global Illumination.

现在，我们在Progressive Lightmapper中支持双面材料。 我们添加了一个新的材质设置，该设置使闪电与背面相互作用。 启用后，在计算全局照明时将考虑几何图形的两侧。

Tree Lightmap Baking

树光照贴图烘焙

Terrain trees can now cast shadows into the baked lightmap for a lightmap static terrain. The trees themselves will be lit using a light probe that is automatically placed above the tree.

地形树现在可以将阴影投射到烘焙的光照图中，以获得光照图静态地形。 树木本身将使用自动放置在树木上方的光探头进行照明。

Lightmap stitching

光照贴图拼接

Lightmap seam stitching makes it easy to get rid of those annoying edge seams in lightmaps.

光照贴图接缝拼接可轻松消除光照贴图中的那些令人讨厌的边缘接缝。

A-Trous filtering

A-Trous过滤

For Unity 2017.2, we have added advanced filtering options with a new A-Trous kernel. The new filter preserves shadow edges and contact shapes much better, while at the same time smoothing out noisy areas.

对于Unity 2017.2，我们使用新的A-Trous内核添加了高级过滤选项。 新的滤镜可以更好地保留阴影边缘和接触形状，同时平滑嘈杂的区域。

Linear Rendering with WebGL 2.0

使用WebGL 2.0进行线性渲染

You can now be sure that linear rendering inputs, outputs, and computation are in the correct color space. The brightness of the final image will be adjusted linearly according to the amount of light in the scene. That means more consistent lighting across your scenes and assets. You can get more details here.

现在，您可以确保线性渲染输入，输出和计算在正确的色彩空间中。 最终图像的亮度将根据场景中的光量线性调整。 这意味着您的场景和资产上的照明更加一致。 您可以 在此处 获得 更多详细信息 。

Linear rendering is now supported on:

现在支持线性渲染：

• Windows, Mac OS X and Linux (Standalone)

  Windows，Mac OS X和Linux(独立)

• Xbox One

Linear rendering is particularly interesting because it allows you to use the Unity Post Processing Stack, including temporal anti-aliasing, and also achieves excellent  results with WebGL.Linear rendering in Unity WebGL player works on any web browser that supports WebGL 2.0.

线性渲染特别有趣，因为它允许您使用 Unity后期处理堆栈 (包括时间抗锯齿)，并通过WebGL获得出色的效果。UnityWebGL Player中的线性渲染可在任何支持WebGL 2.0的Web浏览器上使用。

粒子系统改进 (Particle System improvements)

Editable Custom Data Module Labels

可编辑的自定义数据模块标签

The Custom Data module allows you to specify data that can be used for many different purposes. We’ve made the labels on the curves and gradients editable to allow you to describe what each bit of custom data is used for.

“自定义数据”模块允许您指定可用于许多不同目的的数据。 我们已使曲线和渐变上的标签可编辑，以允许您描述自定义数据的每一位的用途。

Inherit Lifetime for sub-emitter particles

继承子发射器粒子的生命周期

There is a new option in the Inherit dropdown for sub-emitters, allowing them to base their own lifetime on the remaining lifetime of their parent system.

子发射器的“继承”下拉列表中有一个新选项，使子发射器可以将自己的生命周期基于其父系统的剩余生命周期。

This can be useful for creating effects that are guaranteed to only last a specific amount of time, even if they collide and create new particles, for example.

例如，这对于创建保证仅持续特定时间量的效果很有用，即使它们发生碰撞并创建新的粒子也是如此。

Linear Drag

线性阻力

A new option in the Limit Velocity over Lifetime Module allows you to apply linear drag to your particles. Add it to effects with various sized particles in order to have the smaller ones travel further and faster than the larger particles. A great use-case for this is when creating explosion debris effects.

生命周期极限速度模块中的新选项允许您将线性拖动应用于粒子。 将其添加到具有各种尺寸粒子的效果中，以使较小的粒子比较大的粒子更远和更快地传播。 一个很好的用例是在创建爆炸碎片效果时。

Auto-Destruct/Disable

自动销毁/禁用

It’s now possible to destroy or disable a Particle System when it has finished playback. Destroying is great for one-shot effects. Destroying allows you to avoid having to perform your own cleanup code. Disabling, on the other hand, can be useful when you are managing your own pool of Particle System Game Objects.

现在可以在完成播放后销毁或禁用粒子系统。 消灭非常适合单发效果。 通过销毁，您可以避免执行自己的清理代码。 另一方面，在管理自己的“粒子系统游戏对象”池时，禁用很有用。

Burst Emission

突发发射

Bursts counts can now be configured to use the same curve options as many other Particle System properties.

现在可以将爆发计数配置为使用与许多其他“粒子系统”属性相同的曲线选项。

Restart Button

重新启动按钮

We’ve added a Restart Button to the Scene View overlay in order to spare you the trouble of having to press Stop and Play to restart an effect.

我们在“场景视图”叠加图中添加了“重新启动”按钮，以免您不得不按下“停止并播放”来重新启动效果。

实时运营分析 (Live Ops Analytics)

Running a game as a live service means you can adapt your game to your players’ needs, keep your game fresh, and make the experience more enjoyable. In 2017.2,  our Remote Settings feature is officially out of beta.

通过实时服务运行游戏意味着您可以使游戏适应玩家的需求，保持游戏新鲜感，并让游戏体验更加愉悦。 在2017.2中，我们的远程设置功能正式退出测试版。

Remote Settings

远端设定

演示地址

Remote Settings is easy to use. It’s native to the Unity engine and employs an API similar to PlayerPrefs that most Unity developers are familiar with. Recently, we made a significant update to this feature. Remote Settings now supports segments. So you can act directly and immediately on player segments and tailor your game to suit specific groups of players — all without shipping a new binary. The above demo of the upcoming Final Fantasy XV Pocket Edition, a remaster of the original title in the form of an all-new mobile adventure, shows how Remote Settings works in a AAA title.

远程设置 易于使用。 它是Unity引擎的本机，并采用了大多数Unity开发人员都熟悉的类似于PlayerPrefs的API。 最近，我们对该功能进行了重大更新。 远程设置 现在支持细分。 因此，您可以直接对玩家细分采取直接行动，并根据特定的玩家群体定制游戏，而无需交付新的二进制文件。 上面即将发布的最终幻想XV袖珍版的演示，以 全新的移动冒险形式对原始标题进行了重新制作，展示了远程设置在AAA标题中的工作方式。

Remote Settings is now officially live and available on your Analytics dashboard.

远程设置 现已正式启用，并且可以在 Analytics(分析)信息中心上使用 。

全面的其他改进 (Other improvements across the board)

Performance Reporting: Android Native Crash

效果报告：Android本机崩溃

Now, when you use the Performance Reporting service, native crash reports will automatically get sent from your players’ Android devices to the Performance Reporting service.  In the developer dashboard, you’ll be able to see these crash reports alongside your unhandled managed exceptions and native iOS crash reports.  You can enable the Performance Reporting service for your project in the services window in the Editor.

现在，当您使用效果报告服务时，本机崩溃报告将自动从播放器的Android设备发送到性能报告服务。 在开发人员仪表板中，您将能够看到这些崩溃报告以及未处理的托管异常和本机iOS崩溃报告。 您可以在编辑器的“服务”窗口中为项目启用性能报告服务。

Recorder (experimental)

记录仪(实验)

The Recorder captures frames during gameplay and produces image sequences (JPG, PNG, GIF, OpenEXR) and video files (WebM, H.264/Windows only). You can add this feature to the Unity Editor by downloading the Recorder from the asset store.

记录器在游戏过程中捕获帧并生成图像序列(JPG，PNG，GIF，OpenEXR)和视频文件(仅WebM，H.264 / Windows)。 您可以通过 从资产商店 下载 记录 器来将此功能添加到Unity编辑器中 。

您还可以直接从时间轴使用帧记录器轨道触发记录会话：

Package Manager

包装经理

Although Unity user won’t see any change in 2017.2, we wanted to give you a heads up. In 2017.2, we are introducing a Package Manager which will enable a more flexible and modular approach to manage all the components and subsystems that ultimately make up Unity. For this first release, we are exposing an API for enabling internal components to be updated more frequently than the editor (the first pillar of the system). Stay tuned for more details.

尽管Unity用户在2017.2中不会看到任何变化，但我们还是要提请您注意。 在2017.2中，我们将引入一个软件包管理器，该软件包管理器将采用一种更加灵活和模块化的方法来管理最终构成Unity的所有组件和子系统。 对于此第一个版本，我们将公开一个API，该API使内部组件的更新比编辑器(系统的第一Struts)更频繁地更新。 请继续关注以获取更多详细信息。
