Instead, it goes through a series of steps meant to ensure the stability of the physics. While the overall physical model remain the same, the output of these forces is not directly handled by the game engine anymore. Streamlining the physics and engine upgradeĪnother big improvement from Physics 5.0 is the way each force is calculated and applied. PID Tune feature, you may find that your old PID Gains need adjustments to once again provide a good flight experience. PID tune at any point! However, please note that with this flight controller change, if you don't use the A.I. If you are interested in honing your PID tuning skills, you can still de-activate the A.I. PID tune! This new feature, powered by A.I., will make sure your drones always have the best possible PID gains, so that you can focus on your rates and on your flight! On top of that, Liftoff Flight Controller comes with a new feature, A.I. In other words, there wasn't much more we could do, simply because the bulk of performance was lost on a blackbox that we were not at liberty to optimize.Įnter Liftoff Flight Controller, a new, lighter flight controller designed using state-of-the-art Control Theory and Digital Signal Processing techniques to replicate the way your real-life flight controllers work. However, they do all rely on sensor input generated by regular updates of the Unity engine's built-in physics, which are heavy at high frequencies. In the grand scale of things, those operations are actually pretty lightweight. It had a high PID loop frequency and made use of intensive digital signal processing techniques. Liftoff's previous flight controller proved reliable, but also quite performance hungry. With Physics 5.0, we are aiming to have Liftoff run smoothly, and at higher frame rates, even on computers that barely meet Liftoff system requirements. Indeed, Liftoff is a pretty demanding game: a precise simulation comes at a price. Though we are very happy with the state of Liftoff's physics, we suspect that many people do not get to experience them to the fullest extent because of low frame rates. it doesn't add new physics models, but focuses on performances, stability and usability through the rework of some core systems. Physics 4.0 made the aerodynamics simulation better. Physics 3.0 was all about our dynamic thrust model. Through the years, Liftoff's physics have seen several updates. Thank you for your help! Physics 5.0 philosophy Does it fly better? Do you have better performance? Is there anything you'd like to see change? You can get in touch with us on Facebook, Discord and on our Steam forums. We would be very grateful if you could give us your feedback and opinions about it. Help us with your feedback!Ī preview is now available on Liftoff’s experimental branch. To this end, we are proud to announce Physics 5.0, the latest iteration of our physics engine. At LuGus Studios, we are always pushing the boundaries to offer you the definitive, most realistic FPV drone simulation, so you can rely on Liftoff to develop muscle memory and a sense of flow.
