How to fix your vehicles after the update!

Fixing vehicles

A lot of physics changes have occurred in the latest update. If your vehicle doesn’t behave as desired don’t freak out, in most cases some minor adjustments will be needed to get you going. If you still experience issues after trying the suggestions below don’t hesitate to contact us on steam or DISCORD (faster response time).

What if my boat/submarine, … sinks?

In the past pontoon buoyancy increased when the pontoon was pressed deeper into the water (more submerged), since this isn’t realistic we’ve made changes to the calculations. You can easily get your vehicle to work by either adding additional pontoons or losing weight.

What if my underwater propeller is too slow?

Prior to the patch propellers didn’t work properly while underwater; this means that boats that are using regular propellers will turn a lot slower than they did in the past. This is because water is approximately 1000 times denser than air and can be fixed by either making your propeller slower or considering the use of a water propeller. Another thing that might help is using a lower gear ratio since the propeller needs less RPM but more torque while submerged.

My boat is too fast, what now?

In the past pontoons generated too much drag, since we’ve fixed this issue you’ll notice that most boats will fly through water like crazy. To fix this we advise you to tweak your thrusters so that they provide less thrust.

My car bounces/jitters, help!

Suspension physics has changed and damping force has a lot more effect than it used to. Thankfully in 99% of the cases this can easily be fixed by lowering the damping force to a value that is lower than the spring force.

My car is too slow

Due to a variety of reasons cars used to be way too overpowered, since most parts have improved by a lot it’s best if you base your designs on realistic engines and re-tweak the gear ratios depending on your craft.

Transmissions have been improved by a lot and should be ready for use out of the box 99% of the time. Depending on the engine, wheel size and vehicle weight you might want to tweak the “global gear ratio” property based on your needs, this of course doesn’t mean that you won’t be able to change the individual gears as well.

My electrical powered vehicle doesn’t have enough power

Electrical vehicles will probably be underpowered after this update. This is because the electric motor was too overpowered and we had to rebalance it entirely. Yet again this can easily be fixed by using a lower gear ratio (less RPM, but more torque).

There’s also no need in trying to hook up an insane amount of batteries like you could do in the past since the electric motors are capped to approximately 5HP. If needed we advise you to hook up more electric motors or use a more powerful combustion engine.

What if my clutch doesn’t work?

We’ve reversed how the clutch works; now a value equal to 0 means that it has traction and a value of 1 means that it doesn’t.

What if my car suddenly feels like it’s on ice?

In this update we took a major step towards more realistic behavior and to do this we’ve changed the system that defines how wheels make traction. As a result wheels are subject to slip curves both for side to side and front to back traction.

  • If the vehicle keeps skidding left and right: increase sideways friction.
  • If the vehicle has issues with forward and backward: increase forward grip.
  • If the vehicle has understeering issues: try increasing grip on front tires.
  • In case of oversteering: increase sideways traction of the rear tires.

  • Why are my tires burning out so much?

    In the real world a spinning tire has dramatically lower friction than a tire with speed that is lower relative to the ground. As a result if your tires start spinning (usually due to excess torque being applied) holding throttle down will just make the situation worse. In this case you can either:

  • Increase weight.
  • Increase forward traction in the property panel of the wheel.
  • Use less torque (can be achieved via gear rations/different engines).
  • Spread the torque out by hooking up more wheels from the same gearbox or engine. You might also consider to add smoothing.
