Does someone knows ...

Which tab in JFF is related to the movement speed of the node ? Like, my butt is going full retard on me, jiggling at light speed and stuff. I was wondering if I should either raise the linears for it to jiggle other ways and make it less noticeable or look once and for all for the tab that actually tampers with it. Thanks !

Hmm if movement is too 'fast' try lowering timescale in the main tab where inertia tensors are.

 

Also try tightening the inertia tensors a bit (raise the numbers)

 

Not sure if this helps with what you were looking for though.

Too much could be doing it... when you say "light speed" i'm thinking it's a collision issue.

 

try posting your .xml, something might stick out.

Yep, the inertia tensors did the trick, thank you blabba ! 
Thank you too b00m !
