I 'm waiting for more than a year waiting for weighted creases and till now haven’t seen any news about the development
I take it that this is related to SubD’s?
Dale Lear is currently working hard at the foundations that will make “SubD soft creases / variable fillet / darts / fading creases” possible. We have a few items on the YouTrack list that are related but all seem to be locked to internal use only. I’ve added your request to item RH-64740.
Just to manage future expectations - we have several feature requests that have been on the list for over 20 years…
the problem with weighted creases is in many situations the weights do not data translate.
In tsplines, we had to convert the part to nurbs or mesh in order to “bake” the weights.
