Hi,

I try to change the parent Material of the Material Instances which are in a specific folder of my project. I would like to create a function that archieve this and run it from the editor.
Any Idea ?

Thank you !

The solution:


            UMaterial* BaseMat = LoadMaterialFromPath(MaterialPath);
            UMaterialInstance* MatIns = LoadMaterialInstanceFromPath(InstancePath);
            MatIns->Parent = BaseMat;

With loading functions :


 UFUNCTION(BlueprintCallable, Category = "save")
    static FORCEINLINE ObjClass* LoadObjFromPath(const FString& Path)
    {
        if (Path == "") return NULL;

        return Cast<ObjClass>(StaticLoadObject(ObjClass::StaticClass(), NULL, *Path));
    }

    UFUNCTION(BlueprintCallable, Category = "save")
    static FORCEINLINE UMaterial* LoadMaterialFromPath(const FString& Path)
    {
        if (Path == "") return NULL;

        return LoadObjFromPath<UMaterial>(Path);
    }

    UFUNCTION(BlueprintCallable, Category = "save")
    static FORCEINLINE UMaterialInstance* LoadMaterialInstanceFromPath(const FString& Path)
    {
        if (Path == "") return NULL;

        return LoadObjFromPath<UMaterialInstance>(Path);
    }

Is it possible to do it with blueprint?
