As you see, I have made some "BIG" tanks which have a right OBBOX and set large number to their geometries. However, the tanks will still overlap when they get close.
Code:
Type="BOX"
MajorRadius="90.0"
MinorRadius="44.0"
Height="30.0"
ContactPointGeneration="VEHICLE"
How to fix this problem? Please help.

BTW, please comment on the tanks, thank you.
