No, the animation speed doesnt change when the speed increases in the blendspace. Im having this exact problem. I have a project where the character increases velocity as a skill, and i need to change the speed of the whole blendspace to achieve that. Also, you cant change an specific animation play rate through blueprints, you need a montage to do that.
The problem is that im not using a direction/speed based blendspace, but a input axis based one. So my axis are WalkForward and WalkRight. I am looking for a way to change the whole blendspace play rate within the anim blueprint (or other blueprint for the matter).
Any ideas?
