Hi,
 
I'm trying to use suspension in a hinge2 from spring constants that
configure ERP and CFM. I'm using the documentation formula:
 
ERP = h kp / (h kp + kd)
CFM = 1 / (h kp + kd)
 
and my bodys jump .....
 
if i modify with :
 
ERP = h kp / (h  (  kp + kd  )  )
 
it feel really better. Is it a documentation error ? or does i have another
problem ?
 
if i do the same modification with CFM =  1 / (h ( kp + kd ) ) my bodys
jumps again ...
 
 
Laurent
