Yes, i already knew how to change specific animations play rate. Thats not what im asking. But how do you communicate with the play rate of the entire blendspace??? for one or two animations it isnt a problem. With dozens, it is… still looking for a solution 
i just dont want to spent one hour filling my screen with nodes…
I even thought on just doing 3 different blendspaces with the same animations but different speeds… but thats cheap as hell. I cant believe there isnt a way to change an entire blendspace rate within blueprints…
