1.第一次记录：2020.2.05 版本：4.24.2
UnrealEngine initial setup
1. After downloading UnrealEngine4 in the Epic
1-1 First: Start - Options
1-2 then checked :() enter debug symbol - Application
New problems emerged after the collapse for easy viewing detailed reasons
2. UE4 related configuration files
2-1. Delete the C disk cache buffer address and modify UE4 asked the project address
Referring to the content of the article comes from CSDN blog: https://blog.csdn.net/cc13813194235/article/details/53424866
while valid to pro-test version UE4_4.24.2
1. First create a casual game project, choose your project directory
2. Create a complete closed UE4
找到UE4的项目缓存目录
C:\Users\用户名\AppData\Local\UnrealEngine\Common\DerivedDataCache
删除DerivedDataCache
3. Locate the installation directory UE4
4. BaseEngine.ini found file UE_4.24 / Engine / Config in directly with Notepad
5. Edit - Find - Find input box [InstalledDerivedDataBackendGraph]
6. [InstalledDerivedDataBackendGraph] below to modify the content
1 Local=(Type=FileSystem, ReadOnly=false,Clean=false, Flush=false, PurgeTransient=true, DeleteUnused=true,UnusedFileAge=34, FoldersToClean=-1, Path="%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache")
修改为：
1 Local=(Type=FileSystem, ReadOnly=false,Clean=false, Flush=false, PurgeTransient=true, DeleteUnused=true,UnusedFileAge=34, FoldersToClean=-1,Path="%GAMEDIR%DerivedDataCache")
7. After the modifications made to verify the successful modification
1. In BaseEngine.ini file, enter the Find box [DerivedDataBackendGraph]
2. FIG found in the selected text, that is successfully modified and changed cache path project to the project folder
2-2. Delete the online program to build the cache SwarmAgent
Cache directory: C: \ Users \ username \ AppData \ Local \ UnrealEngine \ 4.24 \ Saved \ \ SwarmCache Swarm
delete SwarmCache
3. UE4 related settings
3-1. Setting the blueprint does not compile when UE4 start

1.找到配置文件路径：C:\Users\用户名\AppData\Local\UnrealEngine\4.24\Saved\Config\Windows\Engine.ini
2.打开Engine.ini文件
3.文本内容中添加
[/Script/Engine.Blueprint]
bRecompileOnLoad=False
[/Script/Engine.LevelScriptBlueprint]
bRecompileOnLoad=False
[/Script/Engine.AnimBlueprint]
bRecompileOnLoad=False
4.保存，重启
3-2. 设置仅编译成功时保存
1.在随便打开一个蓝图，在编译的旁边有个倒三角，如图
3-3. 显示编辑器实时信息
1.编辑-编辑器偏好设置-通用-性能-勾选显示帧率和实时信息
崩溃日志
UE4崩溃日志（1）
参照内容来源于虚幻4官方文档：https://docs.unrealengine.com/zh-CN/GettingStarted/RecommendedSpecifications/index.html
里面有虚幻4的硬件配置要求，配套软件版本的需求，以及显卡驱动的需求
因显卡驱动程序原因导致崩溃
关键字：D3D11RHI、Rendering、Building
D3D11 为Direct3D11（渲染管线），RHI 为Render hardware interface 渲染硬件层接口，d3d11.dll 为动态链接库Dynamic Link Library
如图所示：
解决方法：
1.首先进入 NVIDIA GeForce Experience
2.检查更新文件（旁边的三个点）-选择首选项-Studio驱动程序-检查更新文件（如图）
3.检查到更新文件后，下载最新的驱动，自定义安装，勾选恢复默认设置
4.重启电脑（最好重启一下）
UE4崩溃日志（2）
参考内容来源于知乎文章：https://zhuanlan.zhihu.com/p/45508890
该知乎作者写了很多UE4的Bug以及部分崩溃解决方案
Unreal 4 Official Document Content Reference: https://docs.unrealengine.com/zh-CN/Engine/Rendering/Nvidia/NVIDIAAftermath/index.html
Because NVIDIA Aftermath crash
关键字：Aftermath、D3D11Query.cpp] [Line: 111] 、GPU has crashed
Aftermath 是一个轻量化的实用工具，可减轻部分调试工具对性能历史记录的要求。实际上，它相当轻量化，甚至可以包含在发布的游戏中，提供开发者需要的用户电脑数据。程序员可利用 Aftermath 在代码中插入标记，帮助追踪崩溃发生的根源。
Solution:
1. Locate ConsoleVariables.ini, path: the installation disk: UE_4.24 \ Engine \ Config \ ConsoleVariables.ini
2. Found [the Startup]
3. Add the content in the text region
r.DX11NVAfterMathEnabled = 0
r.GPUCrashDebugging = 0
in FIG:
4. save restart UE4
