Hi all!
I’m having a hard time making the limits get applied when a lot of force is put (using a Newton Field to push the character backwards). See video below how I have limits set up, but when the newton force is applied everything rotates a ton forward and seems to ignore my limits.
Thankful for any advice or help.
Hi @Widunder, welcome to the forums! 
This can be a combination of 3 things.
In this case, the first step should be overlapping each connected shape. Gaps between shapes are bad news, because it cannot happen in the real-world. Connected shapes are special in that they can overlap and won’t collide, only grand-children and grand-parents do.
Secondly there is a Limit Stiffness attribute which works like Pose Stiffness does. It’s a strength of how much to try and keep a limb inside of the limit. Try increasing this to 10 or 100.
Have a look here for some visuals.
Hi Marcus and thank you!
Connecting/overlapping the shapes fixed the issue and it’s now working as I expected it too. Thank you so much for the swift and clear response! I learned a lot, cheers!
