编辑器快捷键

按住鼠标右键 + WASD 按住鼠标右键 + 数字键盘8246 按住鼠标右键 + 方向键	在场景中前左后右移动主摄像机注：此时还可通过滚轮来加快和减慢摄像机的速度
按住鼠标右键 + EQ 按住鼠标右键 + 数字键盘97 按住鼠标右键 + PageUp, PageDown	在场景中上下移动主摄像机
按住鼠标右键 + C（Z）按住鼠标右键 + 数字键盘3（1）	不断按C，不断缩写FOV（Filed Of View）不断按Z，不断放大FOV（Filed Of View）松开右键，恢复到原来的FOV 想调整主摄像机的FOV，可修改红框中的数值：
`	调用命令输入框 / 控制台输入框

Alt + 拖曳左键	主摄像机围绕着选中物体来观察
拖曳中键	切换到Top、Bottom、Left、Right、Front、Back视图，拖曳中键，来测量模型的长度
End	让选中物体的Bound落在其下面最近的碰撞上
Shift + End	让选中物体底部中心落在其下面最近的碰撞上（比End更贴合）
Alt + End	让选中物体的轴心点落在其下面最近的碰撞上
W	对选中的物体切换到移动模式注：在工具栏的Settings菜单中有一个Show Transform Widget（显示变换控件）开关。勾选才会显示变换控件
E	对选中的物体切换到旋转模式注：在工具栏的Settings菜单中有一个Show Transform Widget（显示变换控件）开关。勾选才会显示变换控件
R	对选中的物体切换到缩放模式注：在工具栏的Settings菜单中有一个Show Transform Widget（显示变换控件）开关。勾选才会显示变换控件
空格	切换选中物体的操作模式（移动、旋转、缩放）
Ctrl + 拖曳左键	对选中物体的操作模式（移动、旋转、缩放）进行X轴变换
Ctrl + 拖曳右键	对选中物体的操作模式（移动、旋转、缩放）进行Y轴变换
Ctrl + 拖曳中键	按着Ctrl键，朝不同方向拖曳中键，会弹出不同的快捷菜单（如下）：
Alt + 拖曳中键	临时改变锚点的位置注：临时改变锚点的位置后，再次点击后，锚点会重新回来原来位置。
按住V + 鼠标放到三个坐标轴的圆球处（会显示为黄色）并左键拖曳	显示出场景中各个物件的顶点（蓝色），移动物体靠近这些顶点时，会将三个坐标轴的圆球的对齐到顶点上
Alt	移动、旋转、缩放时，复制选中物体
Alt+Shift	移动、旋转、缩放时，让场景运动而保持物体不动地进行物体复制
Shift	①移动、旋转、缩放时，让场景运动而保持物体不动 ②LandScape -- Sculpt（塑造）左键点击来降低地形
Ctrl + G	编组注1：编组的对象必须属于同一个关卡编组后，会在当前关卡中，创建一个AGroupActor对象注2：点击时进行组选，需提前开启组选开关（Ctrl + Shift + G）
Shift + G	取消编组
Alt + A	选中一个对象Obj1后，按Alt + A，进入pick模式点击同关卡其他对象Obj2，即可将Obj2设置为Obj1的父对象注1：这样就可以通过移动Obj2，来一起移动2个对象了注2：设为父子关系的对象必须要在同一个关卡中注3：通过在World Outliner中拖曳对象节点，也可以将不同对象设为父子关系
T	开关半透明选择
G	开关游戏模式
Ctrl + R	开关RealTime模式
H	隐藏选中物体
Ctrl + H	全部显示物体

PC平台开启Shader Model 5预览（缺省）

相关配置信息保存在Saved\Config\Windows\EditorPerProjectUserSettings.ini

[/Script/UnrealEd.EditorPerProjectUserSettings]
PreviewFeatureLevel=3
PreviewPlatformName=None
PreviewShaderFormatName=None
bPreviewFeatureLevelActive=False

PC平台开启Android ES3.1预览

EShaderPlatform对应SP_PCD3D_ES3_1

相关配置信息保存在Saved\Config\Windows\EditorPerProjectUserSettings.ini

[/Script/UnrealEd.EditorPerProjectUserSettings]
PreviewFeatureLevel=1
PreviewPlatformName=Android
PreviewShaderFormatName=GLSL_ES3_1_ANDROID
bPreviewFeatureLevelActive=True

对于Standalone需要带上-FeatureLevelES31或-FeatureLevelES3_1参数才能开启

也可以从编辑器里面启动ES3.1的standalone，如下：

PC平台开启Android ES3.1预览，会使用D3D11的API和hlsl代码来模拟ES3.1逻辑

PC平台缺省开启D3D12

开启后，Editor、Standalone、cook版本都会缺省使用D3D12

设置后，会在DefaultEngine.ini中保存

[/Script/WindowsTargetPlatform.WindowsTargetSettings]
DefaultGraphicsRHI=DefaultGraphicsRHI_DX12

关闭工具条、面板

① 左键点击红圈左上角三角处

② 会显示出Tab标签，点击关闭按钮即可关闭

③ 在Tab标签上右键菜单，可重新隐藏Tab标签

将StaticMesh转换为SkeletalMesh

① 将StaticMesh导出到fbx文件

② 再将fbx文件导回编辑器

将SkeletalMesh转换为StaticMesh

使用MeshEdge查看模型表面三角形

使用Show>Advanced>MeshEdge 来取代线框模式（Wireframe）

使用Quad Overdraw查看模型表面三角形

保持物理模拟后的位置

然后点击Simulate运行场景（SIE，Simulate In Editor）。注：不要选择Selected Viewport来Play，这种方式镜头会动。

Simulate运行之后，物理模拟会将箱子重力跌落。

选中这些箱子，然后右键菜单执行Keep Simulation Changes，执行后即使结束运行时，这些箱子仍然会留在地上。详见：保留模拟修改

保存视角并快速转到视角

使用Ctrl+[0-9]保存视角，使用[0-9]跳跃到那个视角

调整相机速度

缩略图编辑

首先，勾选Thumbnail Edit Mode，开启缩略图编辑模式

然后在目标图标上，通过拖曳左键来旋转图标，拖曳右键来缩放图标

最后，点击Done Editing来结束编辑模式。

场景中的物件均为Actor类型

未运行的场景：

运行起来的场景：

注：黄色字眼的物体为运行时动态创建的Actor
