Determines when a ledge in the source geometry can be traversed, rather than acting as an obstruction. Allows the mesh to flow over low lying obstructions such as curbs and up/down stairways.
This parameter is normally based on how far up/down the agent can step, though often it needs to be set higher because of the way the source geometry is designed. Start with ceil(maxAgentStep / YCellSize) and adjust from there.
