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.

The soft crease weight of the SubD edges are set to 0%, 90%, and 50%.

Steps

  1. Select SubD edges to apply soft crease weight.

    The edges can be from multiple SubDs and in multiple chains.

  2. 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.

The SelSubDEdges command selects different types of edges on selected SubDs.

Steps

  1. Select SubD objects, press Enter.

    The command reports the numbers of different edge types.

  2. Sets what types of edges to be selected.

    The command-line only shows the edge types that the selected SubDs have.

Smooth (Yes/No)

Specifies whether smooth edges will be selected.

Weighted (Yes/No)

Specifies whether soft crease edges will be selected.

The SubDCrease command adds soft crease edges to SubDs.

Crease (Yes/No)
