hairSystems - Self Collide Width Scale is inconsistent

I have 2 same rigs in the scene - rigA and rigB.
I also have script which will launch a small windows and it has a field - textbox and slider that allows me to edit the “Self Collide Width Scale” for all the hairSystems.

rigA was setup at origin with a couple of hairSytems and when I was using my script, using a value of 0.08 for the “Self Collide Width Scale” it gives me the display of boundary that I want.

Now I move the rigB slightly away from rigA, and attach the hairSystems at the same place as rigA. However, as soon as I attach the hairSystem to rigB, the initial value of 0.08 on rigA has now ‘disappeared’ from view. Instead it becomes way smaller and in order for me to view it, I need to increase the value say to 2++.

And so my questions are:

  • Why does this happens? This inconsistency.. I would expect that the value of 0.08 would remains and allows me to view the boundary for both rigs
  • Is this an expected behavior of the hairSystems/ nucleus?
