Custom Animations
To use your own animations, all you must do is create an AnimMontage out of your animation by Right-Click → Create Anim Montage.
Next, go into your new Montage and scroll to the part where you want the Cast to happen.
Right click the Notifies row and Add Notify → Skeleton Notifies → SkillNotify.
This will ensure that this Notify gets called (through the AnimBP) and triggers “Event OnSkillNotify” inside PDA_SkillBase which handles the notify’s behaviour.
You’re all set. This montage now can be used for any type of Skill you’d like!
