What's WRONG with Collision fix tutorials?
Unlock the secrets to optimizing your game's performance and physics!
In this tutorial, we dive deep into the differences between Simple and Complex collisions in Unreal Engine. Understanding when to use a basic collision shape versus a highly detailed, per-polygon collision mesh is crucial for balancing realistic gameplay with smooth frame rates.
What you will learn:
• Simple Collision: How to use basic primitives (boxes, spheres, capsules, and convex hulls) for lightweight, efficient physics calculations and movement routing.
• Complex as simple Collision: When to rely on your static mesh's actual geometry (per-poly collision) for pinpoint accuracy and why it's computationally expensive and should be avoided.
• Debug issues created by wrong settings: A side-by-side comparison illustrating the problems that may arise from wrong setting.
• Best Practices: How to navigate the Collision Complexity settings (e.g., "Use Complex As Simple" vs. "Default") to get the best of both worlds without tanking your framerate.
