Character can't go above max walkable slope

Sorry I’m not following. If you set the max walkable slope angle to 90 degrees, and set the step height high enough, you’ll be able to walk up a cliff. Granted it’s instantaneous, but it would bypass your issue. I think maybe you’re assuming it’s the max slope angle that’s stopping you when it might not be. It’s likely got something to do with how the movement component is set up and the capsule collision. There’s a node called Launch Player that can help fix some of these types of issues by placing the player into an “in air” mode before the dash. But the engine is going to be waiting for that moment you contact the ground again and then it’ll set you back into a “walking” mode automatically. That’s likely the source of your problem. I might actually look into creating a separate pawn that isn’t a character with a sphere collision and switch to that during your dash, and then back to your regular player pawn when not but there’s likely a more elegant solution. Like I said, this isn’t something as simple as a physics simulation and just getting a ball to roll up a slope. There’s a free plugin on the marketplace for allowing players to walk up walls. Might be worth looking for that. I think it’s called Ninja Character Plugin. There’s also another called Directional & Planet Gravity.
