FString matPath = “Material’/Game/StarterContent/Materials/M_Metal_Gold.M_Metal_Gold’”;
UMaterialInstanceConstant* material = Cast(StaticLoadObject(UMaterialInstanceConstant::StaticClass(), nullptr, *(matPath)));
if (material == NULL) {
GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor::Red, TEXT(“Material not found”));
}

This code fail to create UMaterialInstanceConstant.
I do not know why.

The code failed because your asset is a UMaterial, not a UMaterialInstanceConstant. If your code doesn’t care about the material’s implementation details, I’d recommend instead casting it to UMaterialInterface which would correctly work with any material, instanced or not.

Now I can change actor’s material dynamically!
