This hands on tutorial will show how PDG can generate multiple particle streams (wedges) utilizing multiple cores in parallel. In part 1 of this video we will discuss a general Houdini centric workflow where the Particle Stream is created with a few Objects and a Dynamics Operator Network. We will then drop down a TOP Network and use PDG to drive the particle simulation we just created.  

PDG topics discussed are:
  • Houdini centric workflow suggestions for PDG
  • Wedge operator - how to drive Surface Operator parameters through PDG
  • ROP Mantra - how to render image files
  • Wedge Index and Wedge Number attributes
  • PDG Input and Output attributes
  • Partition by Frame operator
  • Image Magick - how to install and use this third party app
  • Wait for All operator
  • ffmpeg Encode Video - how to install and use this third party app

    Quick question, I cannot get the view task output to work from the rop mantra down. It says cannot load the file.
    But if I view task info and click the output image it loads correctly. I have the project settings and all correctly.

    Any ideas on a fix for this.

    Hey Ari, Are the hip files available? Thanks

    Don't understand why there isn't a link to a
    1) starting .hip
    2) completed .hip

    More or less essential to properly follow along.

    @23:10 with the three wedges for the color components, did you forgot what you said earlier about the target parameter override?? That would have given you at least _too_much_ variation in color (3 variants for a given red, 3 greens for each red ==9, and 3 blues for each before ==27. And the seed variants included ==27*3 ==81 variants in total)
