  1. Hi all - I've got a TOPS network to render 25 different sim variations at low resolution just to evaluate them. I've stitched together a contact sheet with imagemagick and found a few I'd like to try compositing with. Now I want to render three specific ones with a different ROP setup that's higher resolution/quality. I've tried branching off of my wedge and doing all kinds of things with the map nodes and partition nodes but nothing has worked. Anyone out there know how to do this? Thanks for reading!
  2. Hi there I am currently making a HDA that takes a mesh, does an infection solve and spits out resulting textures; I have finally got my top graph cooking fine however I am a bit lost as to how the user will actually trigger it from the HDA interface. Promoting the force cook on the topnet doesn't work and even when normally activated, it seems to use up all houdini's threads as opposed to a cook from within the graph. I have also been scouring the pdg python module docs to see if I can trigger the network to cook from a callback script. The furthest I have got on that front is the cook method on both pdg.GraphContext and pdg.Node objects. pdg.GraphContext.cook() seems to want a CookOptions object which I don't know how to generate or manually create. pdg.Node.cook() wants a block argument and I am also lost as to what that is, I've tried using block=1,1 etc I found a py file called top in /houdini/python2.7libs/pdg/job/ which contains a function called cookTopNode. This looks promising however I don't know how to call it nor which module/object it is a member of. I'll provide a scene file if needed, just needs a bit of decluttering first Any help is greatly appreciated. George
  3. ok so some progress with PDG following Ari's tutorial, https://vimeo.com/323291527 but getting ImageMagick running properly on OSX is a total PITA! After installing, adding proper pathing to houdini.env it runs but no support .exr by default. Get the following error So thinking I need to install OpenExr I do so and get openexr 2.3.0 is already installed and up-to-date Any ImageMagick experts able to suggest a solution? Guessing this will be easier on my Ubuntu box....
  4. Hello folks, i'm reading a .json in TOPs, creating string attributes, and collecting. Now, i would like to read those attributes that i created in TOPs from SOP, i'm tryng with @myattr, and pdginput, but no luck. Basically it's the same situation described here: https://www.sidefx.com/forum/topic/66408/ Any idea ? Thanks in advance
  5. I have a few TOPs that save process and save geometry to disc. It takes some time for that work to finish. Do I have to recook the TOPs everytime the file is reopened? It was saved and geometry is still on disk.
  6. I have a Top net with a ropfetch node pointing at an opengl rop. When i render the opengl by cooking the ropfetch it renders the reference plane/ortho grid into the image. Even though i have turnned off its display in the view port. However if i render the opengl directly the grid doesn't render. Not sure if this is a bug. anyone have a solution? thanks.
