Hi, Thanks for reading.

using hair constraints, point 0 and point 12 are pinned,
The type is "permanent" and "same as position"



But only one end can be really pinned from rotation.




Why ???
Is that because the rotation-pin only works on one end, not both?
But what if I want to pin a spider web, which has lot of "ends"(pin orientation)?

And if realy works on one end, which end is OK for rotation-pin?
I try to reverse the point number, but still, the right pin happens at the same end.


And, how to pin both ends orientation?
i really need that.

Thank you very much.

even only one point,12

the orientation pin is not working, why? and what should i do

stucked here,

really need your help,

thank you very much
