SYRIA MAP: Friction error causing motion output on some Tarmac Park surface textures.

[BrassEm]

G'day,

 

There appears to be a problem with particular tarmac park surface textures that interact with the player model sitting on top of it.

 

The texture shakes the model intemittently to the point that the model starts to roll.

 

I have verified the texture in the example supplied. The texture also appears on 03 park for Kiryat Shimone where it behaves the same. Other park locations not using that texture appear stable. I am sure if I test other parks with that texture the problem will occur.

 

As per the supplied example;

A clean F-18 hot on the tarmac with no wind or turbulence set, will rock both graphically and in motion. (See graph.) Eventually the F-18 will start rolling where the SWAY drops off until the aircraft is stopped, and the SWAY starts rocking again. Ensured throttle is Idle but brakes were not set.

 

Parks in Haifa, Rosh Pina are okay but testing for that texture has not been exhaustive. As a side note, other maps Caucasus, Nevada, Gulf test okay.

Found probable cause.

UPDATE: NOISE ALSO FOR OTHER MOTION AXIS OUTPUTS.

 

Oscillations intermittently breaks out simultaneously for the motion outputs as per the graph above and seen in the export.log file;

 

LoGetAngularVelocity() Pitch, Roll, Yaw.

LoGetAccelerationUnits() Surge, Heave, Sway.

 

The whole aircraft literally shakes which you can see on the screen and also feel in the motion.

 

This is on the Syria map. Will try other maps in the same configuration.

 

Further Findings:

 

F-18 Light loadout - Rock and Rolls.

F-18 Heavy loadout - Rock and Rolls dampen out after a couple of minutes.

F-16 Light loadout - Rock and Rolls to take-off (almost.)

F-16 Heavy loadout - Solid.

New Clouds or Old makes no difference.

The severe jolt on the deck of the carrier just sitting there also needs to be fixed...

Isn't that fixed by not saluting???

I get jolts taxiing around the deck as though I'm hitting an imaginary curb.

Sorry to trouble you mods, I have modified my original post as I have narrowed the cause down to a Syria Map texture. Is it possible to move this thread over there to the bugs sections. If not let us know and I will start a new thread there.
