  1. PDG changing work item

    Is there a simple way to change work item name in TopNetwork? I'm sending a bunch of tasks to deadline, and they are named like ropPyro_ropfetch1500_500 , I want to include @wedgeindex in task names, so I could easily find specific tasks that are rendering too long. Thanks.
  2. Hello ! I'm trying to learn a bit of PDG since it might be useful for some of my projects. But I'm having a few issues For one, I wasn't able to find how to remove a work item. What I'm trying to do is search for a string in a bunch of files, and based on that I'll do some other things. Right now I'm simply trying to get to find the string in the files, but first I need the relevant files. So I use the filepattern node for that, but there is a few files for which I don't want. I use a pattern for the extension (*.txt), but there is some files with a specific string (in this case "proxy") in the filename that I would like to ignore. I tried something like "thePath\*.txt ^*proxy*" to get all the txt files without the ones with "proxy" in the name. Didn't work, maybe the syntax is wrong, but moving on. So I have a bunch of files (aka work item) that I want to get rid of. I tried using the split node, but I don't know how to work with PDG attributes. It always either error out, or gives me this I tried "@filename="file.txt" | @pdg_filename="file.txt" | I tried without the quotes, I tried with backticks around the filename part, without any success. What's the correct syntax for this ? I tried reading this, but without much results. I would need an example to understand it. So using expressions didn't work. I then moved on trying it out with Python. There is the "work_item.dirty(True, True)" command, which works as I want, I see the work item being removed in the node UI, but then Houdini freezes, then crashes. So I'm seemingly out of options. There is multiple questions, which are as follows : 1 - Is there a syntax for the file pattern that allows to get all .txt files, without the ones with a specific pattern in the name ? (mockup - "*.txt ^*proxy*") 2 - How to use PDG attributes in a node, as part of an expression ? Kinda like something simple like "@Frame=2", but in this fashion '@filename="file.txt" ' 3 - Why does the work_item.dirty() python command crashes Houdini ? Am I doing something wrong ? Test file attached. The zip contains some random .txt files with names to test out what I want, along with the hip file. pdg_test.zip
  3. Hey guys, I want know how to read or import tractor status to houdini top network. I would want to running some event in topnet when finished tractor job. I have searching and found many site from googling but I don't know how can do this.. please someone tell me any method !
  4. Hello folks, so, i have a bunch of houdini file with a top node at OBJ level, all file have the same structure and are in the same folder I would like to cook the TOP node from external, Python or another TOP graph. I tried in a background script to access with hou.node('/obj/topnet').parm('cookbutton').pressButton(), but it seems that doesn't cook anything Any idea ? Thanks in advance
  5. PDG Question

    Hi! I have small PDG graph that grabbing models by one from disk, doing some basic stuff with it (UV's, materials etc.) Then I load geometry to /geo, in same hip file, where I have camera, lighting setup and render node. So when I clicking on work items in topnet I see models in scene through the camera. Here is my question. Basically I have only one angle for camera that is suitable for bunch of models but not for all, so I need to incorporate some manual camera controls and somehow save camera settings for current work item. Is there a way to change camera settings only for certain work items? How can I setup such thing? Thanks in advance
  6. I have 3 entries in a wedge (each 48 frames) that I would like to render out in 3 different videos, instead of render all iterations out in one video. How can I do that?
  7. 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
  8. I have a heightfield as part of an HDA that is remapped. If I manually press "Compute Range" in the Heightfield Remap sop it works.... but I need to do it from an HDA processor inside Tops. I promoted the "Compute Range" parameter (button) on the HDA. It works. Then I get it inside Tops HDA Processor via the Update HDA Parameter button... BUT in there it comes as a checkbox. If I check the checkbox it does nothing. How does one enable Compute Range from inside an HDA Processor node in tops? If not, is there a way in vex to the the min and max for the voxels of the heightfield? Thanks
  9. Hey! I'm trying to setup a top network which is pretty simple. I have a dop network where I simulate points, and I have a top network to wedge the seed of the pop source. Now I would like to cache out those wedges, and ideally gather them all together to render. I found examples on how to render the points straight away, but nothing that tells me how to cache them. I tried the rop geometry output in top with no luck. anyone that can help me with that? thanks!
  10. Render after SIM TOP

    Hello good people, I keep learning TOPs and integrating those into my workflow. Ran into a RAM shortage when running TOP on 45 wedges 2-6mil pyro, with opengl rendering, montage, and video output. Noticed that TOP rendering/resizing frames as soon as those ready out of the pyro sim. Is there a way to force TOP to Sim all 45 wedges and render after all simulations were done? if I ran everything steps by step I have more then enough RAM. Please see the basic example in attachment. pyro_sim_wedge_renderodf001.hipnc
  11. Pyro source Wedges TOP

    Hello all, TOPs are amazing and definitely boost the amount if iterations I can create overnight. Hope you will help me to fill some blanks. I would like to Wedge pyro source with different noises and amounts of Fuel and temperature (9 different `@wedgeindex` 1-50 frame range) and feed those sources into the wedged pyro sim. Please see the basic setup example is in the attachment. PyroTopTEST005forOF.hiplc
