[ODE] Hinge2 lo-hi limits

Thank you for your help.
But in my case, stops are set one time at the start of the simulation and
values are statics: lo is negative (-178°) and hi is pausitive (+178).
Then i don't understant why limits are disabled automaticaly with those
values whereas it works fine with lower values like lo=-177°, hi=+177° .....
or -90°, +90°
How is it possible that limits can be automaticaly disabled ?
i didn't look at the joint code ... then if some one know the response ...
it should be great :)

Set the both limits twice and you got the result. It is because the limits
have to be consistent all the time, so a higher limit mustn't be lower than
the lower limit and vice versa. You can solve this problem also by checking
the direction of change of the limits and choose the corresponding order of
limit function calls.
Descending limits: 1. set lower, 2. then set upper
Ascending limits: 1. set upper, 2. then set lower stop param.
I've a problem with the hinge 2 vertical axis limits. It seems that when
lo=-177° , hi=177° it works fine but when lo=-178°, hi=178, limits are
First i saw that because lo=-180, hi=180 disabled limits. (of courses angles
are in radians!!)
Does someone know that or i miss something ?
Thank you for your help
