spawn_entity/5waystospeedupgazebo_16.txt | These meshes imported have a very high face count and are not optimised for
launch in Gazebo. The more complex mesh you spawn in Gazebo, the greater the
computational time needed to determine potential collisions and rendering.
Therefore, it is always good practice to downscale any mesh you import into
the simulator. | |

idea not to reduce the Collapse ratio significantly. | |
