Animations with c++ NOT BLUEPRINTS

Ok, going to make some corrections and going over basics:

You need an animation blueprint to be present.
In the animation blueprint you need a slot node going into the final pose. The default one is fine (DefaultGroup.DefaultSlot).

If you want your character to default to ‘Idle’ if nothing is happening, you can connect “Play Idle” to the default slot but it’s not necessary.
In code you can play a montage into that default slot:

a) You need a UPROPERTY where you can specify the Montage:

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Anim)
UAnimMontage *MyMontage;

b) In the Montage make sure it plays into the slot you specified (DefaultGroup.DefaultSlot is the default which should be fine)

c) Play the Montage:

if (MyMontage->IsValidLowLevel())
{
	USkeletalMeshComponent *Mesh = GetMesh();
	if (Mesh)
	{
		UAnimInstance *AnimInst = Mesh->GetAnimInstance();
		if (AnimInst)
		{
			AnimInst->Montage_Play(MyMontage);
		}
	}
}

OR

a) Declare your montage variable in your header file:

UPROPERTY() // not absolutely necessary but highly recommended
UAnimMontage *MyCMontage;

b) In the constructor, load the montage:

static ConstructorHelpers::FObjectFinder<UAnimMontage> MyCMontageObj(TEXT("/Game/ThirdPerson/Animations/ThirdPersonWalk_Montage"));
MyCMontage = MyCMontageObj.Object;

c) Play the montage as before
