The problem here is that you have multiple splines going through that middle CP. It's sure to crease. Good Luck!

 

The main thing is not to run into situations where you need one. Doing that isn't all that easy either it seems...

 

:D

Trust me, I wouldn't do it unless absolutely necessary. The only reason I conjectured on such a thing was a query from another user where 5-pointers were absolutely outlawed.

 

However, the reason for the dangling CP is to try and get the curvature of the "bad" 3rd spline to match up with the other two "good" splines running through the patch.

 

Note the second picture is actually how Hash internally does it's thing - but I think there is a little bit of extra black magic thrown in to keep things smooth nowadays.

 

I remember back in 8.5 - you could always tell a 5-point patch by the telltale triangle that the creasing spline would cause.
