# In the Project window search type “VoxelHullToAStarNavmesh”
# Open the “VoxelHullToAStarNavmesh.cs” script in any code editor
# Change any line of the script, i.e. add a line “int repro;” anywhere and save the file
# Go back to Unity Editor and for the assets reload to finish
# When the reload is finished stop the recording in the Profiler window
# In the Profiler window look for a usage spike
