Point physics control how particles, particle systems, weather, flags, contrails, and antenna interact with the environment. This includes wind, water, density, and collisions with the BSP. Essentially anything that can be suspended in the atmosphere or water is simulated this way.

They are primarily controlled by density and friction parameters.

The following are related functions that you can use in your scenario scripts and/or debug globals that you can enter into the developer console for troubleshooting.



(debug_point_physics [boolean])

Renders green or red markers wherever point_physics are being simulated, except for the weather_particle_system. This includes flags, antenna, contrails, particles, and particle_systems. It can help to enable framerate_throttle for these markers to render consistently.
