New Modeling tools

  • Path Deform SOP deforms geometry to follow the shape of a curve.

  • Chain SOP repeats one or more pieces of geometry along a curve.

  • Attribute From Pieces SOP creates an attribute controlling what piece will be copied to points, randomly or based various rules.

  • Mask by Feature SOP creates a point attribute “mask” based on visibility/lighting, letting you limit the effect of other nodes to areas that are visible, or facing a certain direction, or in shadow.

  • Scatter and Align SOP scatters points across a surface with randomized scale and orientation attributes for use with Copy to Points.

Improved tools

  • Attribute Paint SOP has improved user interface.

  • Poly Bevel SOP has improved bevels and more convenient interaction in the viewer. You can ⇧ Shift-click edges in the viewer to add them to the bevel, and ⌃ Ctrl-click edges to remove them. You can also easily add loops, change the bevel size and the number of divisions in the viewer.

  • UV Flatten SOP is redesigned and now performs island straightening.

  • Bend SOP can now mirror the bend across the start plane using the Deform in Both Directions parameter. Also fixed some edge cases with Bend handle interactions.

  • The grouping nodes are faster and respond more quickly to interruption by the ⎋ Esc key.

  • The geometry spreadsheet now has an option to display values with full numeric precision.

  • Many more SOP node types are now compile-able.

  • When the Bound SOP creates a transform attribute it now sets the attribute type to Matrix instead of None.

  • The Transform Pieces SOP now supports getting transforms from packed primitives in the second and third inputs.

  • Enumerate SOP now takes a piece attribute to enumerate elements of the pieces separately.

  • SOP geometry now supports dictionary attributes, an attribute type where each element (point, vertex, primitive/face, or the whole geometry/detail) can store a key/value map.
