How do i disable animation optimizations on player blueprint?

It’s an enum on the mesh component of your character. You can set that in the default properties of your actor, through blueprint code, or C++.

In the editor you can go to the default properties of your Character blueprint, and find the following property:

	UPROPERTY(EditAnywhere, AdvancedDisplay, BlueprintReadWrite, Category=SkeletalMesh)
	TEnumAsByte<EMeshComponentUpdateFlag::Type> MeshComponentUpdateFlag;
