  1. Vellum cloth and frequency

    Hello, You have 3 defferents ways to do this: - adding 3 pops winds, one large freq, one middle and one small. (not a good solution to me, I don't like the pop wind not beautifull enough) - inside a pop vop, adding 3 differents noise (Curlnoise can be nicer), with always the same rules of big, medium and small frequence noise - You can simulate a wind using smoke solver (or pyro), and advecting you cloth with the vel grid. Animation looks more natural, with wind shadows ... You can mix those three possibilities as well. Hope it's help. Mathieu Negrel
  2. Check on the houdini environnements variables list, might have something, not sure https://www.sidefx.com/docs/houdini/ref/env.html
  3. CHOPs + Compile Blocks

    Hello, Assuming you are in H18.5 with the new variant attribut. for me chop is not a good option in your case. It's gonna be a real nightmare to you if you want to add variation in your bend ... What you can do is to bend your geometries right after the copy with a curl deformer much more faster. After that you just need to add chop effect on attributs. It's much more effective to me. Hope it's help. Mathieu Negrel. copy_index.hip copy_index.hip
  4. displacement is not working in hqueue

    Can you attach an outpulog, because is current error in Hqueue, it can't apply the remap variable fron local server letters to unc path for the render nodes. Hope it's help Mathieu
  5. OCTANE_PDG_HQUEUE_WINDOWS

    Hello dear Computer grahics friends, I wish you all the best for this year, full of RBD destructions, magicals effects, cloth sims ... I start this year with a very boring subject as rendering octane render images using with PDG and HQUEUE on windows 10 My jobs are running successly even if at the end I don't have any output images. Log erros: *** OCTANE API MSG: Could not load 'Q:\RESSOURCES\TEXTURES\EnvMap\substance\sequence\substanceHDR.001.exr:rgba'. [Octane] 12:46:00 INFOR: [save image] -------- Saving the EXR "Q:/PROJECT/dev/04_3D/assets/Exterior/render_farm/MDL/work/houdini/scenes/Model/render/render_farm_Model_withOctaneNode_v001.Octane_ROP1.0001.exr" file *** OCTANE API MSG: OpenEXR: Cannot open image file "Q:\PROJECT\dev\04_3D\assets\Exterior\render_farm\MDL\work\houdini\scenes\Model\render\render_farm_Model_withOctaneNode_v001.Octane_ROP1.0001.exr". No such file or directory. Work around: If i switch manually all my paths from the server letter to the UNC path, evrything work fine. View with the sideFX support, I had HOUDINI_PATHMAP = {'Q:/': '//***.***.*.*/folder','Q:\\': '//**.***.*.**/folder'}. This additional variable fixed this issue to my "houdini nodes" but not for "octane render nodes" If somebody have any idea to fix this issue ? Best regards, Mathieu Negrel
  6. Hqueue submit with Rez

    for the houdini support, env var: exemple: HOUDINI_PATHMAP = { "c:/temp": "/tmp", "/mnt/render": "//storage/share/render" } HOUDINI_PATHMAP = { "old": "new" } Looks like it's work. I am currently doing some test.
  7. Hqueue submit with Rez

    Hello Evryone, Context: I am currently building a VFX pipeline based on "Rez" system for dynamic environnement resolution on Windows 10. My question is about the job submition on hqueue. Evrything work fine, except when my job is calculating, houdini can not find my textures or writing any bgeo on server, due to the windows server letter mapping. log error exemple: *** OCTANE API MSG: Could not load 'Q:\RESSOURCES\TEXTURES\EnvMap\substance\sequence\substanceHDR.011.exr:rgba'. if I change the map path to a UNC path, evrything work fine like this: '\\***.***.*.*\tutu\RESSOURCES\TEXTURES\EnvMap\substance\sequence\ where "\\***.***.*.*\tutu\" = "Q:" Work around: To fix this issue it looks like I have 2 solutions : Making a script who switch the windows letter path to a UNC path before sending the job -> brute force and not a very elegant way Using the default hqueue hda's and adding my custom variables -> look more natural way to me but I have no idea how it's work, i try to add a PYTHONPATH env, nothing changes, I try to changes the HQCOMMANDS, nothing changed ... Questions: Does anyone have experencing custom environement in hqueue or custom batch command using the default rop nodes, 'simulation' and 'render'? If somebody have any idea to fix the fact that hqueue can't read a path using letters (the hqserver.ini is configurated well I think) Thanks for you time. I really hope you have a solution, except to switch to linux :-) Best Regards Mathieu Rez: https://github.com/nerdvegas/rez
  8. fbx and CHOPS

    I found Interpolate node. works perfect
  9. fbx and CHOPS

    Hello, I am currently trying to blend 2 fbx in chopnet context using the fbx reader. The general idea is to create automatic preroll blending restPose to Animation. My problem is when I blend the fbx (from rest to animation) whithout same numbers of channels the "simpleblend" node doesn`t work. I would like to kwon if it's possible to compare to clip in order to delete the unused channels. Thanks for your time. Mathieu N. best regards
  10. crowd simulation

    Hi evryone, I start working on a rat crowd sequence. Evrything works well. My only problem is when I build my rat agent I have this difference between my fbx in hello and the baked agent. If somebody have an answer. I try changing the deform skin parameters. cheers. mathieu N
  11. hq sim and otls

    Hello evryone, I started using hq sim and hq render. I am wondering if I can rendering a rop geometrie inside a HDA? I don`t think I can`t because It seems logical that my rop geometrie are lock. The other question is when you use a geometrie node inside a ropnet and you connect it to a hq sim and it s doesn`t seem to work as well. this is the log: The Houdini 15.0.244.16 environment has been initialized. Traceback (most recent call last): File "/prod/prod2/Projets/2000/hqueue/shared/houdini_distros/hfs.linux-x86_64/houdini/scripts/hqueue/hq_run_sim_without_slices.py", line 4, in <module> hqlib.callFunctionWithHQParms(hqlib.runSimulationWithoutSlices) File "/prod/softprod/apps/houdini/15.0.244.16/linux/houdini/scripts/hqueue/hqlib.py", line 1864, in callFunctionWithHQParms return function(**kwargs) File "/prod/softprod/apps/houdini/15.0.244.16/linux/houdini/scripts/hqueue/hqlib.py", line 1575, in runSimulationWithoutSlices alf_prog_parm = rop.parm("alfprogress") AttributeError: 'NoneType' object has no attribute 'parm' looks strage to me. thanks anyway. mathieu N
  12. are you working in python for the dictionary?
  13. Foreach, multiple outputs

    voui voila je gambade
  14. Foreach, multiple outputs

    try the new for each loop. look working fine. You can duplicate the output just a thought
