In fact I began with a truck config and made the jeep when my son requested a 4WD ;-) The Truck had a wider wheelbase but suffered the same problems in plib.
The engine is a harrier-like jet engine with 180 degree vectoring nozzle (for reverse). So no torque here. It appears that the ground property handling in plib is somehow erraneous. When you look at the properties of the gears you can see very fast changing in the ground friction factor and the compression length, even with brakes on. Somehow it doesn't get to a stable state and constantly bumps from one wheel to another. This is very exaggerated in areas with changing terrain. In OSG the ground properties are solid and only change when driving from grass to road, etc. I was very surprised to see how well the jeep behaves in OSG (been driving through the ardennes yesterday). Steep slopes and even ramp jumps are not a problem (...but big fun!). > Nice jeep, BTW. > Thanks, next is airlift for the jeep. > Stewart > > Greetings Detlef > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Splunk Inc. > Still grepping through log files to find problems?
