Collision Meshes

Overview

Collision meshes are used to improve in-game physics performance. They can also be used to stop players or vehicles catching on small protrusions from meshes, and generally smoothing out player movement over complex shapes.

Tips

• Unlike shadow hulls, collision meshes do not have to be "watertight", open edges are allowed. However, bear in mind that things in the game will only collide with front-facing polys, so a single flat plane would only have collision on one side of it.
• Collision meshes are automatically optimised by the game to use polygons rather than triangles. Therefore, co-planar triangles will be optimised down into a single n-sided polygon, for efficiency and performance.
