[edit] Exporting Geometry From Houdini
There are several ways to export geometry from Houdini. Currently Houdini only supports writing of single objects to disk in the geometry FileFormat of your choice but there are no support entire scene exporters, such as Collada or FilmBox currently.
As usual, the export format is governed by the filename extension that you provide.
[edit] Geometry ROP and ROP Output Driver SOP
Most convenient for exporting sequences of geometry, in a ROP context ( '/out' or a ROPnet of your own) there is an operator called the GeometryROP which you can point at an object and if you use $F in your filename (See FilenameSyntax), you can set a range of frames to export. There is an equivalent SOP called the ROPOutputDriverSOP which does very much the same thing. These are especially convenient if you plan to export the geometry repeatedly as the node remembers its settings.
[edit] Opmenu: Save Geometry... =
Each SOP node has a RMB menu in which there is an entry called "Save Geometry..." which will save that node's geometry instantly to the file format of your choice by way of a pop-up file requestor.
[edit] Scripted export
There are several ways to export geometry using the scripting languages Hscript and HOM. You could create ROP nodes and execute them from your script or you could export geometry instantly.
[edit] Hscript
- opsave : this is an hscript command to save geometry. It can handle sequences or, if you wish, use it within a loop of your own construction.
[edit] HOM
- hou.Geometry.saveToFile : this is the HOM function to save a node's geometry to file.
