Root Cause

A NavMeshObstacle component has Carve mode enabled on a static object, causing unnecessary navmesh carving updates that degrade performance.

中文

NavMeshObstacle 组件在静态对象上启用了雕刻模式，导致不必要的导航网格雕刻更新，从而降低性能。

Workarounds

  1. 95% success Disable Carve mode on static obstacles: Select the GameObject, in the NavMeshObstacle component, uncheck 'Carve'. Use this code snippet to automate: GetComponent<NavMeshObstacle>().carving = false; 
    Disable Carve mode on static obstacles: Select the GameObject, in the NavMeshObstacle component, uncheck 'Carve'. Use this code snippet to automate: GetComponent<NavMeshObstacle>().carving = false;
  2. 85% success If the obstacle is intended to move, attach a script that toggles carving on movement: void Update() { if (transform.hasChanged) { GetComponent<NavMeshObstacle>().carving = true; } else { GetComponent<NavMeshObstacle>().carving = false; } }

中文步骤

  1. Disable Carve mode on static obstacles: Select the GameObject, in the NavMeshObstacle component, uncheck 'Carve'. Use this code snippet to automate: GetComponent<NavMeshObstacle>().carving = false;
  2. If the obstacle is intended to move, attach a script that toggles carving on movement: void Update() { if (transform.hasChanged) { GetComponent<NavMeshObstacle>().carving = true; } else { GetComponent<NavMeshObstacle>().carving = false; } }

Dead Ends

Common approaches that don't work:

  1. Disable and re-enable the NavMeshObstacle component at runtime 90% fail

    This does not change the Carve mode setting and the static obstacle still triggers carving warnings.

  2. Increase the carving update interval in NavMesh settings 85% fail

    The warning is about the mode being inappropriate for static objects, not about update frequency.
