Is the SBD pin contraint broken in 9.0.757? I can't seem to set a point to pin the cloth to, nor do I see the guide sphere. See attached hip, or try it yourself.
create default cloth object
connect to cloth pin constraint
connect to a gravity
connect to a cloth solver
run it and it just falls. fiddle with the constrain to animation switch on the constraint DOP or the Guide Options… still I get nothing.
I'm not having any problem with the Pin Constraint. In your file; - Make sure you have the Constrained Object set to clothobject1 - Constrained Points set to a point number, ie. 70 - Toggle on Constrain To Animation
