  1. Ah, got it. Interesting question, usually it works the opposite way: you define your global variables via environment variables.
  2. What do you mean by "global variables"?
  3. Run Python script after Houdini starts

    subprocess.Popen([HOUDINI, ['C:/temp/script.py'], 'argument_one']) That gives me what I need. The only thing I don't know how to run a function from script.py after import...
  4. I am launching Houdini with subprocess: HOUDINI = 'C:/Houdini 18.0.287/bin/houdinifx.exe' subprocess.Popen(HOUDINI) How can I import a Python and run a necessary function after Houdini is launched (import open_asset; open_asset.open())? In Maya I can send MEL command to be executed after Maya starts (and import script with this command): subprocess.Popen('C:/Maya 2019/bin/maya.exe', '-command', "python('execfile(\"path_to_the_script\"')") How can I do something like this in Houdini? The 123.py is not a solution, because I don`t need to run a script each time, only in certain cases, and the scripts are different each time. I need this to open an asset file from Shotgun, for example.
  5. By the "fields" I meant the half-frame for TV broadcasting. I recall I struggle to get fields out of Maya render when I was working on TV in the past millennium. I did not know they are still alive.
  6. Looks nice! I see the fields... did not expect anybody uses fields these days
  7. Getting Creative with Vex and Python

    I think there is no magic behind this, you just need tons of practice, repetition usually works when you learn new stuff. If you are not able to solve any simple task by yourself, it means that you are not ready yet, repeat more and more tutorials, the are plenty of them now. ABC: always be coding!
  8. Water/whitewater flicker with redshift

    Also, you may render with AOVs (passes) and it can help to understand which part of the shading produce an issue.
  9. I think you can project SOP mesh on terrain and then do the simulation.
  10. Solaris camera

    I was thinking if SESI built a new system to manage shots renderings, I would better utilize this system, instead of trying to replicate an old workflow in the new environment. I mean I don`t need to store materials with an asset, even opposite, I like the idea of material library shared between assets and shots. I just have no idea how this system is meant to be used. I saw a couple of Solari's tutorials, but they did not cover this topic on a high level, what I am actually interested in...
  11. Solaris camera

    Sounds like I can stay in Mantra world for now But I am still curious, do you have any idea what would be material assignment workflow with Karma? I guess with Mantra the common practice was to store materials with assets and in LOP`s there is the ability to use the material library and do the assignment right before the rendering in the LOP context using geometry groups. I think SESI designed a very powerful system which should be a better version of Katana, but I am confused about how it should be used at a high level in complex project with a lot of shots.
  12. Solaris camera

    What are the Horizontal and Vertical Aperture parameters in Solaris camera? It's not the same aperture we use to in photography, more like a film size parameter, which is confusing. The F-stop parameter (which defines the aperture size in real camera if I not mistaken) is also confusing, you need to use crazy numbers like 100 and more to get a more or less sharp image. Do those values meant to be completely far away from real camera values? Also, is there a way to save renderings in Karma viewport, as it was possible with Legacy Render View (Add image to History).
  13. Houdini 18 is Out!

    Does Karma available on 18.0.287?
  14. Hair and fur question

    Lucky for us, we can use whatever we need, the data is the same, it`s just personal preference on how to organize it. Take a look here for more info about using shelves workflow.
  15. Hair and fur question

    I guess the main reasons are: structuring your network and provide some out of the box solutions. If you are more comfortable to do all the grooming in SOP it's totally fine, hairs are just curves. You can dive inside the guide groom and hair generate objects and learn some useful techniques (until SESI rewrite them in C++) for your SOP setups.
