Introducing Aerodynamic Forces [Studio Beta]

[FGmm_r2]

@Widgex

Could you allow us developers to tune the air density vs height in a number sequence + also the wind system (both relative or altitude based).

We are considering ways to expose the wind profiles (i.e. Air Density at different heights). What exactly do you mean by “in a number sequence”? It would be good to hear what you (and others) think a good way of exposing Air Density at different heights could be.

@Widgex

Also I would appreciate a readout of the current air density percent at a part location, this would be useful for simulating the power loss of piston engines at higher altitudes.

@Widgex

Providing the aerodynamic force as a vector 3 acting on a part would be useful for calculating things like re-entry heating. Separating them between lift and drag may be useful. (If you all go about this could you please add the total force acting on a part as a vector 3?

Hmmm… we have considered exposing specific Aero forces through something similar to the Sensor approach we have used in the past. See: SensorBase | Documentation - Roblox Creator Hub
Would something like that work for your use case?

@MCWither_Storm

Does this affect how your character moves around though?

Yes it does! Take a look at Example 3 in the initial post for an example of this

@kni0002

I’m not too sure if the water creates drag on the sail boats hull or if it is still effected by the wind?

We are hoping to take a closer look at Hydrodynamics (Drag forces in water). It turns out that the Aerodynamic force model approach we used for this release can be mostly applied to water as well. Stay tuned for this.

@cartler

Will air pressure or temperature ever be simulated?

This is certainly on the long term vision. No promises here but it is very aligned with where we would like to go. Note: If you get a chance, take a look at the recent “Engine Innovations” RDC talk where we talk a bit more about the Aerodynamics / Fluid Dynamics roadmap. (The session videos might not be public yet but hopefully will be soon)
