# 大致步骤
|
||||
使用UnrealEditor-Cmd执行资源导入、处理、输出功能。
|
||||
|
||||
1. 导入资产 (这段可以参考FBX)
|
||||
1. 角色
|
||||
2. 动画 FBX
|
||||
2. 处理资产
|
||||
1. IKRig
|
||||
2. RetargetRig
|
||||
3. ControlRig?
|
||||
3. 输出资产
|
||||
1. FBX？
|
||||
2. 使用MovieRenderQueue 渲染 MP4？
|
||||
|
||||
## 短期需求
|
||||
1. AI 动捕、或者GPT生成 BVH、FBX。
|
||||
2. 特定骨骼结构。
|
||||
3. UE骨骼确定。
|
||||
4. 可能需要高并发(后面再考虑)
|
||||
5. 输出视频。
|
||||
6. 工期1~2周。
|
||||
|
||||
## 需要解决的问题是
|
||||
- [ ] 支持多种格式的文件
|
||||
- [ ] `CustomCommandFunction`编写以及生成**IKRig**、**IKRetarget**资产
|
||||
- [ ] 输出FBX或者MP4
|
||||
|
||||
## 输出文件
|
||||
- *.BVH
|
||||
-
|
||||
|
||||
## 生产环境
|
||||
使用Docker或者其他容器工具制作处理用的镜像，之后使用群集系统控制运行？
|
||||
|
||||
## CustomCommandFunction
|
||||
关检测 UCommandlet
|
||||
|
||||
# 测试方法
|
||||
```bash
|
||||
D:\UnrealEngine\UE_5.1\Engine\Binaries\Win64\UnrealEditor-Cmd.exe D:\UnrealEngine\Project\AIAutomationTools\AIAutomationTools.uproject -run=AIAnimationAutomationCommandlet
|
||||
```
|
||||
|
||||
如果带有配置文件
|
||||
```bash
|
||||
D:\UnrealEngine\UE_5.1\Engine\Binaries\Win64\UnrealEditor-Cmd.exe D:\UnrealEngine\Project\AIAutomationTools\AIAutomationTools.uproject -run=AIAnimationAutomationCommandlet -importsettings=C:\\Users\\BlueRose\\Desktop\\ImportJson.json
|
||||
```
|
||||
|
||||
```json
|
||||
{
|
||||
"ImportGroups": [
|
||||
{
|
||||
"GroupName": "Group11",
|
||||
//导入文件名
|
||||
"Filenames": [
|
||||
"C:\\Users\\BlueRose\\Desktop\\untitled2_Anim.FBX"
|
||||
],
|
||||
//生成资产的文件夹
|
||||
"DestinationPath": "Animation",
|
||||
//使用的Factory类名
|
||||
"FactoryName": "FbxFactory",
|
||||
"bReplaceExisting": 1,
|
||||
"bSkipReadOnly": 0,
|
||||
//导入动画资产的设置
|
||||
"ImportSettings": {
|
||||
"OriginalImportType": 2,
|
||||
"MeshTypeToImport": 2,
|
||||
"Skeleton": "/Game/1/untitled2_Skeleton.untitled2_Skeleton"
|
||||
}
|
||||
}
|
||||
]
|
||||
}
|
||||
```

# 其他资料
|
||||
## IKRig & IKRetarget=
|
||||
`Engine\Plugins\Animation\IKRig`
|
||||
- FAssetTypeActions_AnimationAssetRetarget
|
||||
- FAssetTypeActions_IKRigDefinition:UIKRigDefinition
|
||||
- FAssetTypeActions_IKRetargeter:UIKRetargeter
|
||||
|
||||
## Retarger
|
||||
```c++
|
||||
/** The runtime processor that converts an input pose from a source skeleton into an output pose on a target skeleton.
|
||||
* To use:
|
||||
* 1. Initialize a processor with a Source/Target skeletal mesh and a UIKRetargeter asset.
|
||||
* 2. Call RunRetargeter and pass in a source pose as an array of global-space transforms
|
||||
* 3. RunRetargeter returns an array of global space transforms for the target skeleton.
|
||||

## UEditorUtilityLibrary
|
||||
|
||||
|
||||
##
|
||||
Python参考：
|
||||
`Plugins\MovieScene\MovieRenderPipeline\Content\Python`
|
||||
|
||||
|
||||
## 渲染影片（旧版）
|
||||
MovieRenderPipelineCommandLine
|
||||
```bash
|
||||
"D:\Program Files\UE_4.24\Engine\Binaries\Win64\UE4Editor.exe"
|
||||
D:\Projects\UnrealProjects\renderMovieTest\renderMovieTest.uproject
|
||||
/Game/maps/shot0010
|
||||
-MovieSceneCaptureType="/Script/MovieSceneCapture.AutomatedLevelSequenceCapture"
|
||||
-LevelSequence="/Game/Sequences/Shot0010"
|
||||
-MovieFolder="D:\Projects\UnrealProjects\renderMovieTest\outputs"
|
||||
-NoLoadingScreen -game
|
||||
```
|
||||
|
||||
void FMovieRenderPipelineCoreModule::StartupModule() 处理CommandLine变量
|
||||
```c++
|
||||
// Look to see if they supplied arguments on the command line indicating they wish to render a movie.
|
||||
if (IsTryingToRenderMovieFromCommandLine(SequenceAssetValue, SettingsAssetValue, MoviePipelineLocalExecutorClassType, MoviePipelineClassType))
|
||||
{
|
||||
UE_LOG(LogMovieRenderPipeline, Log, TEXT("Detected that the user intends to render a movie. Waiting until engine loop init is complete to ensure "));
|
||||
// Register a hook to wait until the engine has finished loading to increase the likelihood that the desired classes are loaded.
|
||||
FCoreUObjectDelegates::PostLoadMapWithWorld.AddRaw(this, &FMovieRenderPipelineCoreModule::OnMapLoadFinished);
|
||||
}
|
||||
```
|
||||
通过委托调用渲染，最终到void FMovieRenderPipelineCoreModule::InitializeCommandLineMovieRender()
|
||||
|
||||
```c++
|
||||
void FMovieRenderPipelineCoreModule::InitializeCommandLineMovieRender()
|
||||
{

#if WITH_EDITOR
|
||||
//const bool bIsGameMode = !GEditor;
|
||||
//if (!bIsGameMode)
|
||||
//{
|
||||
// UE_LOG(LogMovieRenderPipeline, Fatal, TEXT("Command Line Renders must be performed in -game mode, otherwise use the editor ui/python and PIE. Add -game to your command line arguments."));
|
||||
// FPlatformMisc::RequestExitWithStatus(false, MoviePipelineErrorCodes::Critical);
|
||||
// return;
|
||||
//}
|
||||
#endif
|
||||
|
||||
// Attempt to convert their command line arguments into the required objects.
|
||||
UMoviePipelineExecutorBase* ExecutorBase = nullptr;
|

UMoviePipelineQueue* Queue = nullptr;
|

uint8 ReturnCode = ParseMovieRenderData(SequenceAssetValue, SettingsAssetValue, MoviePipelineLocalExecutorClassType, MoviePipelineClassType,
|

/*Out*/ Queue, /*Out*/ ExecutorBase);
|
||||
if (!ensureMsgf(ExecutorBase, TEXT("There was a failure parsing the command line and a movie render cannot be started. Check the log for more details.")))
|
||||
{
|
||||
// Take the failure return code from the detection of our command line arguments.
|
||||
FPlatformMisc::RequestExitWithStatus(/*Force*/ false, /*ReturnCode*/ ReturnCode);
|
||||
return;
|
||||
}
|
||||
else
|

UE_LOG(LogMovieRenderPipeline, Log, TEXT("Successfully detected and loaded required movie arguments. Rendering will begin once the map is loaded."));
|

if (Queue)
|

{
|
||||
UE_LOG(LogMovieRenderPipeline, Log, TEXT("NumJobs: %d ExecutorClass: %s"), Queue->GetJobs().Num(), *ExecutorBase->GetClass()->GetName());
|
||||
}
|
||||
else
|
||||
{
|
||||
UE_LOG(LogMovieRenderPipeline, Log, TEXT("ExecutorClass: %s"), *ExecutorBase->GetClass()->GetName());
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
// We add the Executor to the root set. It will own all of the configuration data so this keeps it nicely in memory until finished,
|
||||
// and means we only have to add/remove one thing from the root set, everything else uses normal outer ownership.
|
||||
ExecutorBase->AddToRoot();
|
||||
ExecutorBase->OnExecutorFinished().AddRaw(this, &FMovieRenderPipelineCoreModule::OnCommandLineMovieRenderCompleted);
|
||||
ExecutorBase->OnExecutorErrored().AddRaw(this, &FMovieRenderPipelineCoreModule::OnCommandLineMovieRenderErrored);
|
||||
|
||||
ExecutorBase->Execute(Queue);
|
||||
}

|

在 TaskGraph 中，无论是 Event->Wait() 还是 FTaskGraphInterface::Get().WaitUntilTaskCompletes() ，最终都是调用到 FTaskGraphImplementation::WaitUntilTasksComplete 中的。

|

- [x] 导播台除了文字、音频还有哪些数据会传递到AI端？

- 目前只有文字
|
