Refining nav mesh generation

It should come as no surprise that the complexity of an environment directly affects the time it takes for the system to generate a nav mesh. Conversely, if the generation time is shorter, the resulting nav mesh may be less precise. In most cases, your final system will involve a trade-off between computation speed and precision. This means it is mandatory, as a game developer, to understand how to properly set up your nav mesh generation.

In this section, I will provide you with some advice on how to optimize the way a nav mesh is generated.

Influencing nav mesh resolution

The next test we will perform involves modifying the resolution of a nav mesh. Start by following these steps:

1. Open the Gym_NavMesh_02 level.
2. If it is not already enabled, select the Top view.
3. In the Outliner panel, select the Recast Nav Mesh actor.
4. In the Details panel, check the following properties:
   • Draw Tile Bounds
   • Draw Tile Bounds Times
   • Draw Tile Build...
