Try the things your game uses

  • Walk behind and in front of the grass. Check sorting in both dense and sparse areas.
  • Move and zoom the camera, leave the area, then return. Confirm the plants are still in the right places.
  • Try wind, shadows and the interaction shapes used by your characters.
  • Add, move and remove plants through your gameplay controls. Check the visible result, not only the returned count.

Check saving separately

  • In the Editor, try temporary Play Mode edits, Save on Stop and a manual save. Stop Play Mode and check the result.
  • Save a backup, change a few plants, then load it. Confirm that Delete Backup leaves the plants alone.
  • In a Player build, test your own save system. Writing back to Editor assets is not available there.

Test a build on the target hardware

Use Unity's Profiler to measure your scene. Check camera movement, dense patches and large runtime edits. Editor windows add their own cost, so also compare a Player build.
