Developer Fabiano Dias created a smooth obstacle avoidance system in Unreal Engine 5 using Blueprints. The system fires sphere traces every frame on both sides of the character, and when a trace hits a wall, it drives an additive blendspace to adjust the character's orientation. The capsule radius also dynamically adjusts for tight spaces, producing fluid sidestep movement similar to Assassin's Creed crowd mechanics. Full project files including documentation, variable explanations, wall detection logic, and reset behavior are available on Patreon.
