    controling rbd objects

    Thanks guys!! I´ll have a look Cheers Erik
  2. Hi good people. I was wondering if there is a clever way to control rbd-object into a specific end-position. Say I have 8-10 objects that I want to be placed in an exact position in the end of my simulation. Cheers Erik
  3. Very very nice showreel. Keep it comming. Erik
  4. Hi good folks I am having troubles understanding why my setup does not work. What I want is a twistcontrol on my tube-geometry. I have done some reseach on the subject and found some examples that I does not fully understand. Hope to get some enlightment :-) Cheers Erik

    Image per primitive

    Hi. Here is a file with two ways of fetching files via Python. My next goal is to put several imagesequences in the same folder and have different sequences pr primitive. I miss a smart Python-trick to isolate the different filenames in a list. Let say I have 300 frames in one list called [ fileA.0000.jpg -> fileA.0099.jpg, fileB.0000.jpg -> fileB.0099.jpg, fileC.0000.jpg -> fileC.0099.jpg ] How can I make a new list containing only containing [ fileA, fileB, fileC ] ?? Cheers Erik fileOnPrim_v002.hipnc

    Image per primitive

    Hi Thomas Thank you for guiding me in the right direction. Here is the expression so far: import os thepath = os.listdir("U:/martin/awesome 3d stuff/") mod = len(thepath) primnum = int(lvar("PR")) myimagenumber = primnum % mod tex = ("U:/martin/awesome 3d stuff/" + thepath[myimagenumber]) return tex Next step is to make a variable from a nulls file-parameter, so that I dont have to write the images path in the expression. Just to make it easier to point at the files. Thanks again :-) Erik
  8. Hi good folks!! I am playing with Python(expression) i Houdini and I am allready stuck with some syntax-problems. What I want is to assign a primitiveattribute(string) called "map" with this Hscript-expression like this: $HIP\pic\butterfly`$PR % 7+1`.pic but i Python. My goal is to point at a folder, on my harddrive, with random jpg`s(or like) and let the expression figure the rest out. What I have so fare is: import os file = os.filepath("U:erik/pictures") texturepath = file[primitivenumber] - Here I am stucked!! return texturepath Is there a method to this like the above descriped Hscript?? Thank you very much!! Erik
  9. Here is the scene. Its nearly all done in the shader. Erik oceanFX_test_v001.hipnc.hip
  10. Hi all. This how far I have come so far. I would like to continue with some whitewater splash and maybe some mist. I wonder if its possible to use the Mist-tool and Whitewater-tool without the FLIP-tank approach. Thanks for helping me so far :-) Cheers Erik https://vimeo.com/67623946
  11. Hi Martin. Great - Thank you very much!! Its exactly what I was trying to figure out. Cheers Erik
  12. Hi again. So now I had a chance to have a look on the examples from the other thread. I still have problems on how to ude the SDF Volume. What I understand the UniformVolume-shader fills a manifold geometry with a, yes, volume - and it looks cool and exactly what I am trying to acchive. But I have troubles due to my lack of knowledge about volumes and how to convert them into something usefull in the context of oceanFX. What I have found is that I can convert the SDF-volume into a polygon-mesh and the use the extrudeVolume-SOP to get the manifold geometry the UniformVolume-shader needs But it seems to be a cumbersome and heavy workflow. Cheers Erik
  13. Cool. Thanks Martin. I´ll check it out :-) Erik
  14. Hi all. I`ve spent some hours trying to figure out how to shade and render the new ocean FX-tool in H12.5. Especially the volumeoption gives med some trouble to figure out. There is not a lot in the documentation about the workflow. Does any one of you tried it with succes, maybe shed some light on the subject? Thanks a lot. Erik
  15. Hi folks. Is there any chance one of you could explain how to set up the HOcean_Ocean_Eval in displacement. I cant make it work. Thanks a lot Cheers Erik
