Vehicles now sliding sideways on sharp turns since last server deploy of Agni main grid

[dd Temin]

Vehicles  (Dune buggy car) now severly sliding sideways on sharp turns  ... since last server deploy of Agni main grid.

It seems like   the physics value  for friction  has changed ...    thus becomming very slipery.

I am not sure this is the actual cause....but  this is how its  effected.

the cars are  on a prim surface  not land.

We have 2 private island sims...and both exhibit this problem.

Its not effecting airplanes...........so this is why i was guessing   about physics friction.

This could be an effect of the new Physics Engine that was in the Server Update 2 weeks ago.

Sounds to me like they have improved the physics. Try taking a high speed turn in your car. I bet you slide sideways a little.

except the part where that is supposed to be controlled by the vehicle script.... under angular and linear deflection.

UPDATE on details of problem:

Two   vehicle parameters have been effected  ...  since the Havok physics   update .

vehicle_linear_motor_friction_TIMESCALE in Y axis

Vehicle_Linear_Motor_direction in the Y axis

Also it is  sensitive to the  global direction that the vehicle is traveling in when sharp turn is made .

If vehicle is going north or south  and turns to the east or west...all works normal......

BUt  if the vehicle is traveling east or west    and turns north or south      the vehicle fails to turn properly and  slides  severly.

This also is affecting the Ski Jump at Breakaway.
