Motion Operators

Basics

1. Random scatter

Copy to Points

Scatter: generate points

VEX

@density>0.0: create a group for all points with density > 0.0

$FF * 0.02: take our current frame number

VOP

basically visual version of VEX, exposing all the global variables

Point VOP: manipulate points using VOP

MMB > Promote to Parameter for upper level control

• useful for $FF expressions that won’t evaluate in lower levels

Exporting

Any node used for export in Houdini has a ROP in its name

• ROP Geometry Output
  • default output: $HIP/geo/$HIPNAME.$OS.$F.bgeo.sc
  • .bgeo stands for file format, .sc is the compressed lightweight version (removable)
    • use any 3d file extension .obj .fbx
  • $OS = Operator Name
  • $HIP = Project Name
