1. *.Build.cs 引用编辑器模块
? ? ? ? //编辑器模块
? ? ? ? if (Target.bBuildEditor)
? ? ? ? {
? ? ? ? ? ? PublicDependencyModuleNames.AddRange(new string[] {
? ? ? ? ? ? ? ? "UnrealEd",
????????????????"MeshDescription",
????????????????"RawMesh",
? ? ? ? ? ? ? ? //"*****",//其他编辑器模块
? ? ? ? ? ? });
? ? ? ? }
2. *.cpp 实现
????????#if WITH_EDITOR
? ? ? ? ? ? ? ? 编辑器头文件
????????????????或应用的编辑器实现
? ? ? ? #else?
? ? ? ? ? ? ? ? 非编辑器实现
????????#endif
（1）引用编辑器头文件 ，例如
#if WITH_EDITOR
? #include "Factories/MaterialFactoryNew.h"
? #include "Runtime\Engine\Classes\Materials\MaterialExpressionTextureSample.h"
#endif
?（2）实现，例如
FString fName = FPaths::GetBaseFilename(fsTex);
?? ??? ?UTexture2D* ?DiffuseTexture = FCCommonFun::GetLocalTexture(fsTex, TEXT("/***Design/***_Texture/")/*,false,false*/);
?? ??? ?FString MaterialBaseName = "M_";
?? ??? ?MaterialBaseName += fName;
?? ??? ?FString PackageName = "/***Design/***_Material/";
?? ??? ?PackageName += MaterialBaseName;
?? ??? ?UPackage* Package = CreatePackage(NULL, *PackageName);
?? ??? ?FString sMaterialResouce = TEXT("Material'") + PackageName + TEXT(".") + MaterialBaseName + TEXT("'");
?? ??? ?UMaterialInterface * ScreenMaterial0 = Cast<UMaterialInterface>(StaticLoadObject(UMaterialInterface::StaticClass(), nullptr, *sMaterialResouce));
?? ??? ?if (IsValid(ScreenMaterial0))
?? ??? ?{
?? ??? ??? ?m_RMaterialMap.Add(ScreenMaterial0);
?? ??? ?}
?? ??? ?else
?? ??? ?{
#if WITH_EDITOR
?? ??? ??? ?auto MaterialFactory = NewObject<UMaterialFactoryNew>();
?? ??? ??? ?UMaterial* UnrealMaterial00 = (UMaterial*)MaterialFactory->FactoryCreateNew(UMaterial::StaticClass(), Package, *MaterialBaseName, RF_Standalone | RF_Public, NULL, GWarn);
?? ??? ??? ?Package->SetDirtyFlag(true);
?? ??? ??? ?//make texture sampler
?? ??? ??? ?UMaterialExpressionTextureSample* TextureExpression = NewObject<UMaterialExpressionTextureSample>(UnrealMaterial00);
?? ??? ??? ?TextureExpression->Texture = DiffuseTexture;
?? ??? ??? ?TextureExpression->SamplerType = SAMPLERTYPE_Color;
?? ??? ??? ?UnrealMaterial00->Expressions.Add(TextureExpression);
?? ??? ??? ?UnrealMaterial00->BaseColor.Expression = TextureExpression;
?? ??? ??? ?FAssetRegistryModule::AssetCreated(UnrealMaterial00);
?? ??? ??? ?UnrealMaterial00->PreEditChange(NULL);
?? ??? ??? ?UnrealMaterial00->PostEditChange();
?? ??? ??? ?m_RMaterialMap.Add(UnrealMaterial00);
#else
?? ??? ??? ??? ?UMaterialInterface * ScreenMaterial1 = Cast<UMaterialInterface>(StaticLoadObject(UMaterialInterface::StaticClass(), nullptr, TEXT("Material'/Game/GS_Material/NewMaterial.NewMaterial'")));
?? ??? ??? ??? ?UMaterialInstanceDynamic* UnrealMaterialDynamic = UMaterialInstanceDynamic::Create(ScreenMaterial1, NULL);
?? ??? ??? ??? ?UnrealMaterialDynamic->SetTextureParameterValue("BaseTex", DiffuseTexture);//修改材质实例的参数
?? ??? ??? ??? ?m_RMaterialMap.Add(UnrealMaterialDynamic);
?? ??? ??? ??? ?FAssetRegistryModule::AssetCreated(UnrealMaterialDynamic);
#endif //WITH_EDITOR
?? ??? ?}
?? ??? Package->FullyLoad();
