It's funny how slow things fall in engine when they're obeying all the same laws of physics as they would in reality. The falling meat has a number of simple numbers to describe its initial speed at spawn, mass, speed of rotation. It's a simple matter to play around with them until they seem right, but as others have said, sound plays a huge part in conveying their plausible physicality.
Hey Wil, I just had a quick comment regarding reality. Are you guys attempting to replicate the experience of gravity on Oddworld?

On Earth we know that objects accelerate at about 9.8 [m/s^2] (near the surface).

Perhaps someone has done the math already for Oddworld?

We know that Oddworld's surface area is ten times that of Earth: A_odd = 10*A_earth; R_odd = sqrt(10)*R_earth; R_earth = 6378100 [m]

As assumption we can take the density of Oddworld to be the same as Earth's: rho_earth = rho_odd = 5515 [kg/m^3]

Volume of Oddworld: V_odd = (4/3)*pi*(R_odd)^3 = 3.4369E22 [m^3]

Mass of Oddworld: M_odd = rho * V_odd = 1.8954E26 [kg]

G = 6.6738E-11 [m^3]/[kg * s^2] (yes, I'm assuming the Oddverse has a "universal gravitational constant" equivalent to our universe)

Finally, surface gravity of oddworld: g_odd = (G * M_odd)/(R_odd)^2 = 31 [m/s^2]


That's about three times the surface gravity of Earth!


Not expecting you guys to act on this...just food for thought.
