SubD smoothed edge: infinitely sharp vs crease value =1

[uwesketch]

An edge marked as "infinitely sharp" will be subdivided as a non-smooth edge.
When removing the "infinitely sharp" flag, the crease value changes to be 1. It would be nice, if the edge would be marked as smooth when subdividing with a value of 1. Otherwise I have to set the crease value to 0.99 to get a sharp smoothed edge.

I'm not sure I quite follow.

Can you post some screenshot and a sample model to illustrate?
Also, are you using Relative Sharpness?

Hi Thom

I hope below screenshots clarify.

Why is the smoothing of a creased edge depending on the number of iterations when the value is a relative value?
For me it would be easier, if a relative value of 1 would as well create a smooth edge. Like this one can easily distinguish between infnite and a relative value of 1.

absolute crease values:

corresponding relative values:

Oh, I see, infinitely sharp edges override the original smooth-property of the edge. Yea - that's a bug. Thanks for reporting! I've logged it to my issue tracker and will be looking into why this happens.

Sorry for the inconvenience.
