SubD Edit Tools > Soft Crease |
The SubDCrease command lets you create and modify the weight of "soft crease" along selected SubD edges. SubD surface tangent and curvature are continuous across soft crease edges.
Steps
-
Select SubD edges to apply soft crease weight.
The edges can be from multiple SubDs and in multiple chains.
-
When the command prompts "Select highlighted vertex":
-
Type a number between 0 and 100 to apply a constant weight to every selected edge.
-
Click on a weight label to edit the weight at that location.
A highlighted dot of "P" appears and you are prompted to enter a weight.
The weight blends from a label to another across the edge points in between.
-
Click on a highlighted edge point to add an additional weight label.
-
Command-line options
CreaseAll
Makes the selected edges hard creases equivalent to the Crease command.
ConstantWeight
Applies the same weight value to every selected edge.
SmallerText/LargerText
Changes the size of the weight labels so they are appropriate for your current viewing state.
Notes
-
Crease weight of 100% makes sharpest soft creases. It does not make hard creases like the Crease command.
A soft crease weight at 100% (left) and a hard crease (right). -
The weight values applied to SubD vertices can be cleared by the RemoveCrease command.
-
The SelSubDEdges command can be used to select all soft crease edges on selected SubDs for editing.
-
The ShowEdges command highlights soft crease edges.

Steps
