问题现象

假如用以下方式加载动画蓝图：

FString AnimBPStringTest = "AnimBlueprint'/Game/ThirdPerson/Animations/ThirdPerson_AnimBP.ThirdPerson_AnimBP'";
UAnimBlueprint* AnimationBP = LoadObject<UAnimBlueprint>(nullptr, *AnimBPStringTest);

在PIE和Standalone模式下都可加载成功，但是一旦打包运行（打包配置中添加了该资源cook）就会加载失败，并提示如下错误：

LogUObjectGlobals:Warning: Failed to find object 'AnimBlueprint /Game/ThirdPerson/Animations/ThirdPerson_AnimBP.ThirdPerson_AnimBP'
解决办法

方式一：

FString AnimClassPath = "Class'/Game/mixamo/Heidi/IcloneAnimBP.IcloneAnimBP_C'";
UClass* AnimationClass = LoadObject<UClass>(nullptr, *AnimClassPath);
SKMesh->SetAnimInstanceClass(AnimationClass);

方式二：

UClass* AnimClass = LoadClass<UAnimInstance>(nullptr,
                    TEXT("AnimBlueprint'/Game/ABP_Test.ABP_Test_C'"));
SKMesh->SetAnimInstanceClass(AnimClass);
