Character Animation does not working

I have a character mesh with two animations (just Idle and Walk).
I watched all the UE4 Persona Tutorials on Youtube and this one that some people recomended: Unreal Engine 4 Tutorial: Custom Character (english) - YouTube

I did exactly what those tutorials are showing, but the animation to my character does not work yet.

When I hit play, the character still in the “T position”.

But inside the MainCharacter Blueprint, the Idle animation works properly.

As long I don’t want my character jumping, I took off the “Is in Air?” part of the Blueprint:

I can not figure out where’s my mistake. Since everything is according the tutorials: 1D Blend Space, setting the right animation blueprint on the mesh, setting the right mesh in MyCharacterBlueprint, etc.

Well, I figured it out.
I forgot to set the animation blueprint here:
