UE5 Quick Tip: Adding Collision to Nanite Meshes

If you've imported one of the nanite meshes from Quixel Bridge into your UE5 project, you probably noticed there's no collision enabled by default.

This is a pretty and easy quick fix.

The first and easiest method is to open the static mesh in question, and set the Collision Complexity value to Use Complex Collision As Simple. However, complex collision can be quite expensive, especially meshes with more complex geometry. However, you will get the most accurate collisions with this method.

Another option that will yield better performance is to generate a simple collision object. You can do this by selecting the "Collision" drop-down in the top toolbar and selecting Add Box Simplified Collision. You also have the option to add a sphere or capsule collision if that suits the mesh better.
