Unity Navmesh FAQ

What it's good for:

• Static levels (you can carve though)
• Very fast path finding of many many agents (500+)
• Fast baking
• Very simple navigation needs such as open/close door, static areas to avoid or be attracted to

What it's bad for:

• Dynamic level
• influence map a.k.a AI-on-a-grid

Troubleshooting:

• agent wobbles near the target - turn off Auto Braking
• Pathfinding is slow - turn down the navmesh fidelity by increasing Navigation>Bake>Advanced>Manual Voxel Size
• Agents take a while before they move - usually happens with 100+ agents or very complex path, increase pathfindingIterationsPerFrame
• profiler shows high cpu cost for navmesh avoidance - lower avoidanceCollidionTime
• need cover? Check out the shooter sample of Panda BT
