Whether you are a feature film VFX artist, a game developer or a commercial studio, Houdini 17.5 brings you new and enhanced tools to meet your most demanding production requirements.

Houdini 17.5 is a important release that includes a number of key features including the introduction of PDG | Procedural Dependency Graph. This new technology  is available in the upcoming release of Houdini 17.5 as a new Houdini operating context called TOPs (Task Operators) and as a standalone application called PilotPDG™.

PDG is designed to:

  • Describe complex dependencies visually with nodes
  • Transform that dependency description into a set of actionable, schedulable tasks
  • Distribute those tasks with the help of a scheduler and compute them in parallel
In addition there are a wide variety of feature enhancements in Houdini 17.5 which you can learn about on the 17.5 What's New page.

    sidefx 太伟大了。每个版本都有非常大的变化

  • ThomasHelzle 1 year ago  | 

    Since I started using Houdini as my main 3D application some years ago, each update was bliss.
    This one is no exception and is showing a vision and perspective that I find really fantastic - and it's a frigging dot-update...

    Next stop: replace the current VEX editor with an integrated version of MS Code... :-)

    Thank YOU!

    Next step: Multiselection of points in the Curve Sop :D :D :D

  • OneBigTree 1 year ago  | 

    Truly amazing! Now SideFX can probably start tackling the really, really difficult features, like creating text, numerical input for point positions, extrude along curve (not deform extrusion by spine), resizable panes in the quadview and single-key viewport switching and render layers. I know they can do it.
