Is BP_Omar a controller or a character? if its a character controlled by Player Controller you can either Get Controlled Pawn from player controller or Get Player Pawn and then cast to BP_Omar.
Hey there @Zocabulapo! Welcome to the community! So you’re casting to the player controller and not the pawn it’s controlling. You could use the Get controlled Pawn node to get the pawn it’s in control of, and from there you can actually cast it!
