  1. Hello, we built an asset to cache and version our sims/caches I extended it to be able to use the renderfarm to sim things out. To do this I added a ROP in the asset, with the HQueue simulation node. I then use the topmost interface/parameters to 'click' on the 'Submit Job' button on that HQueue Simulation node down below. However, unless I do a 'allow editing of contents' on my HDA, it fails on the farm with the following code: ......................... ImportError: No module named sgtk Traceback (most recent call last): File "/our-hou-path/scripts/hqueue/hq_run_sim_without_slices.py", line 4, in <module> hqlib.callFunctionWithHQParms(hqlib.runSimulationWithoutSlices) File "/our-hou-path/linux/houdini/scripts/hqueue/hqlib.py", line 1862, in callFunctionWithHQParms return function(**kwargs) File "/our-hou-path/linux/houdini/scripts/hqueue/hqlib.py", line 1575, in runSimulationWithoutSlices alf_prog_parm.set(1) File "/hou-shared-path/shared/houdini_distros/hfs.linux-x86_64/houdini/python2.7libs/hou.py", line 34294, in set return _hou.Parm_set(*args) hou.PermissionError: Failed to modify node or parameter because of a permission error. Possible causes include locked assets, takes, product permissions or user specified permissions It seems that unless I don't unlock the asset, the submit job can't be clicked. Here's how i linked the interface button to the submit button Thanks for your input.
  2. Hi Guys Sorry if this post is in the wrong place but I didn't know where else to post it, I currently can not open/use Houdini 16 on my system and have no real way to investigate why, I have tried installing different builds of H16 and always get the same error usually after I open the software after the splash screen. In the rare event I do get passed the splash screen and able to use H16 it eventually crashes with the same error. I should mention: - H15.5 works just fine on my main system. - H16 works fine on an older unused system I have laying around (much reduced spec than the system I would like to run H16 on). Main PC Spec: CPU: 5th gen Intel core i7 hex core GPU: Nvidia GeForce GTX 1080 RAM: 64GB RAM at 2333MHz SSD: 512 GB OS: Win 10 Pro Old Unused PC Spec That H16 does work on: CPU: 2nd gen Intel core i7 Quad core GPU: Nvidia GeForce GTX 660TI RAM 16GB RAM at about 800MHz SSD: 128GB OS: Win 10 pro I have attached a screen shot of the error, I appreciate this could be anything but if any one knows why this could be happening or even where to start investigating why please get in touch, as I really don't know what to do. Many Thanks Nav
  3. When I start Houdini I recently get this error message in the Python console. Python 2.7.6 (default, Oct 26 2016, 20:33:43) [GCC 4.8.4] on linux2 Houdini 16.0.557 hou module imported.

  4. Hey! SOP Solver Cooked in Immediate mode, cached results incorrect--- That is the error I received. I was trying to use particles as a source for pyro and it gave me this error. What exactly does it mean? What is cooked in intermediate mode? Thanks
  5. So I have an odd problem I haven't been able to figure out yet. I have a Synology DS716+II NAS raid and using it as a shared drive so I can use HQueue to render jobs on other machines. That all works fine to render on the farm, however when I write alembic data to the NAS, I get an error everytime I try to read it back into Houdini or into maya. If I write the exact same alembic data to a local drive on my computer, then there are no read errors. And this seems to only happen with alembic and fbx data. I can write hip files and bgeo's all day to the network drive and everything reads fine, just alembic and fbx data that fails when trying to read it back from the Network drive. Does this make sense to anyone.? I would think if this was a firewall problem or permissions type thing, then no data should read or write to the NAS. The exact error I get when trying to read alembic data back into Houdini from the network drive is "Error evaluating alembic file". ANy help would be appreciated. Thanks E
  6. Hi! I have a strange issue. When I write many files at the same time, some of them breaks. It can be 200-300 files simultaneously size of about 10 Mb, or 70-80 files of 100 Mb - I have the same result: files exists, but 5-10% raise read error in Houdini. They have a normal size or less than normal on the storage. I tried this on the old storage and on the newest storage (with perfect access time, speed, caching etc) - the same result. Houdini 16 behaves just like Houdini 15.5. When I starting write this files, we have write errors on the storage from other software like Nuke or just write files from the OS. Another picture is not observed: when we write hundreds exrs from nuke - there is no file breaks on the storage. This occurs for many months, and I think the reason is in the method of writing files from Houdini. Is there a technology to change the method of writing geometry from Houdini (flags, variables)?
  7. With the recent 16.0.6 update, Houdini added games shelf tools. one of these tools is vertex animation. I've been trying to integrate my particle system into Unreal Engine 4 for the past 2 days. When I try to render the vertex animation subnetwork gives this error: Error Error rendering child: /out/vertex_animation_textures/mantra11 Diving into the subnetwork there's two nodes that give errors the first node gives this error: Error Zero resolution for camera '/out/vertex_animation_textures/sprite_obj/cam1' and the second node gives this error: Error Error rendering input: /out/vertex_animation_textures/mantra11 From what I've read from another odforce forum post the problem seems to be that the HDA for vertex animations textures need to be used correctly. Quote from Gramx's post: " Hi Luiz, I have been looking at the hip files and it seems that you have a newer version of the Vertex Animation Textures Asset. I get an error saying incomplete asset definition. Are you able to send over the latest asset or will it be available in the next Daily Houdini build. I am running 16.0.542 Thanks Graham " Gramx's post Shouldn't the tool just work on it's own? Or am I doing something wrong? Any help into the right direction would really be appreciated, maybe even an example of the particle working in Unreal. Cheers, Callan RubberParticles.hipnc
  8. Hi all, I am quite new to Houdini, but ran into a problem connecting image files/textures to the new Arnold 5.0 Standard Surface Shader. I have a standard studio setup with a sphere and area lights on the sides and on top. When I assign a Arnold Standard Shader, go into the network and remove the Standard node and attach a Standard Surface node all renders out fine. But whenever I attach an image/texture to, for example the Base Color, my scene does not render AT ALL. I noticed it is also not generating .tx textures even though everything is set up correct (i think)...
  9. Hello, I'm playing with bullet dynamics in Houdini. But I'm having quite often one problem - strange motion in e.g. small shards on ground plane. They don't stop moving even after few seconds after they fell on the floor. They are not changing position but just slightly rotating. This motion seems to go on and on... According to docs Linear/Angular Treshold parameter in RBD Packed Object should fix it, but it doesn't seem to have any effect. Have you experienced this type of error and if - have you solved it? Thanks
  10. Hi guys, I have a complicated old HIP file from V14 and I want to update it to use it in 15.5 and you see when I open it I face with multiple errors on reading the file and I can't save the list for editing them after pressing ok. So I thought maybe there is a way that I can save the error list for editing or a log file. what do you do for this kind of situation? Thank you
  11. Hi everyone, I'm facing a weird problem with HQueue. I have 3 client machines, firewall disable on all of them, they have all the necessary authorizations and access, the file I want to render can be open on each of them with the exact same path (and I've tried to open it on each of them, it works perfectly) but... when I submit the job to HQueue, it fails on all machines with this message : "......................... return function(**kwargs) File "C:\Program Files\Side Effects Software\Houdini\houdini\scripts\hqueue\hqlib.py", line 1489, in simulateSlice controls_dop = _loadHipFileAndGetNode(hip_file, controls_node) File "C:\Program Files\Side Effects Software\Houdini\houdini\scripts\hqueue\hqlib.py", line 331, in _loadHipFileAndGetNode _loadHipFile(hip_file, error_logger) File "C:\Program Files\Side Effects Software\Houdini\houdini\scripts\hqueue\hqlib.py", line 362, in _loadHipFile hou.hipFile.load(hip_file) File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.16/houdini/python2.7libs\houpythonportion.py", line 518, in decorator return func(*args, **kwargs) File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.16/houdini/python2.7libs\hou.py", line 22697, in load return _hou.hipFile_load(*args, **kwargs) hou.OperationFailed: The attempted operation failed. Unable to open file: X:/3d_Projects/MyProject/Houdini/Beach_4.hip" My file is in an other shared folder than the specific one for HQueue, but I even try to submit it from the HQueue shared folder and it doesn't work either. Does anyone have a clue what is going on ? I am stuck...
  12. Hi! I'm pretty new in Houdini, but I have to improve very quickly in 1 and a half month so i'm watching the basic tutorials in the sideFX site. Following a lesson about digital assets I had to create different rocks and try to put them in a curve. But after uploading one single rock and trying to change the expression in $Hip/geo/rock_`padzero(3, ("../copy1", rockNum, 1))`.bgeo it gives me this two errors Unable to read file ".../.../geo/rock_001.bgeo" Unable to evaluate expression (Bad data type for function or operation (/obj/sphere_object1/file1/file)). why is that? i'm pretty sure this is a simple question but without having any professor I don't know who to ask. thank you!
  13. Hey all! Quick question for everybody. I have not been able to set mulptile RBD objects as triggers for a crowd simulation for some reason. I can't share the scene file but can create another one to exemplify my dilemma if that would help. I have setup a crowd simulation with 4 triggers for 4 separate RBD objects. This is in Houdini 15.0 which is necessary for the Houdini Engine integration with Cinema 4D. The problem is that the 4 RBD objects simulate but only the last linked RBD object (number 4) affects the clones. I suppose it's overwriting the other RBD triggers? Could anybody give me a tip on how to rig this differently so it recognizes all 4 RBD objects in the Ragdoll simulation. Best regards, Sam Welker
  14. Hey guys! I have a really strange problem with Houdini. I just reinstalled my os (windows 10) and installed houdini apprentice but I can't start it. It says that my drivers can't run openGL 3.3 but I installed the latest version of them. I tried to remove all my graphic card's drivers and reinstall them and same error. I have a gtx 560 ti. I never had this problem before and I can't get rid of it. Any idea? Thanks!
  15. Hi guys, don't know if it's normal... it's the first time I noticed it in particle surfacing using FLIP in Houdini 15.5. Well it happens only when I have compressed fluid and I try to surface it with the default particle fluid surface. All default settings and bammm... it gives me an error in frame 1, It simply don't finish the meshing... If I mesh it after frame 1 it works perfectly. Any tips? Actually it's not a huge problem... I can mesh it from frame 2 or sim it from frame 0 but I would like to know why it's not working. Cheers, Myke
  16. Hi, I have this error in the Console when I start rendering Unknown operator type: animatrix::Sop/pathDeform::1.00 But then it renders ok I've tried to create new scene, reset the Houdini.env file... and nothing seems to solve. Do you have any idea? Thanks
  17. Hello everyone, I recently installed H15 on my system and tried to follow zombie hit tutorial from sidefx ( ). Everything went fine except when ball hits the first zombie, it disappears and only first zombie appears to affected and that too in very weird way. I followed the tutorial thoroughly. I have attached the scene file and video. I don't know why it happened. Thanks in advance. EDIT: Problem fixed. Forgot to put collision layer for all. zombiev1.hip zombie_error_video.rar
  18. Hi, Im rendering a turntable of a cloud. I have the strange error that mantra always crashes after the fourth frame. I just get a windows that mantra has stopped working, nothing else. I would be thankful for some tips to delimit the error. Do I have something like a render log for example? kind regards Jon Edit: I switched to the lates Houdini 15 build there the issue is gone.
  19. Hi I have a problem when I am trying to render my cached crowd simulation. If I render the dopimport everything renders fine and I get a bunch of soldiers running around. Though as soon as I write my crowd sim to disk as bgeo or bgeo.gz (either using the ROP or the file node) and read them back in something strange happens. In the viewport everything still seems fine but as you can see in the image it does something strange during the render. If I cache my packed crowd sim to alembic it renders fine but it gets really slow and the file is huge compared to a bgeo sequence. So I would rather fix this problem of rendering the bgeo sequence. If I create any other packed object, it renders fine. It just seems to occur when I try to render a crowd simulation that is cached to disk. I am using H14.0.335 Does anyone know what is causing this and how to fix it? Thanks in advance!
  20. Hi I’m new to Houdini and trying to use exhelp command for educational purpose in Houdini 14. Unfortunately this message show up every time I try. >>> exhelp fit File "<console>", line 1 exhelp fit ^ SyntaxError: invalid syntax Am I typing something wrong or this feature has removed from this Houdini version module? Thanks for reading
  21. I'm exporting some simulated geometry to Maya from Houdini and I keep getting the following error: UVs aren't per-vertex or per-polygon per-vertex, skipping And it won't load any UVs... All of the geometry has UVs in houdini and there are no "null" uvs (one point has 0,0,0 but that is correct). I've deleted all groups except the inside and outside primitive groups of the fracture and all attributes except: point: P vertex: N, uv Alembic format is HDF5. I don't know what else to try!
  22. M getting following error in log after launching render, /houdini/python2.7libs\\hou.py", line 42828, in load\n return _hou.hipFile_load(*args, **kwargs)\n', 'OperationFailed: The attempted operation failed.\nUnable to open file: Z:/filePath/FileName.hip Can any one help me with solving this issue!!! Thanks in advance. note: 1. m using houdini 13. 2. M trying to launch render in farm, local machine its working fine. Only difference between farm machine and local machine is graphics card.
  23. If a node fails to cook I get this nice error message with middle mouse click on the affected node. How can I copy this error message into clipboard, or how can I get those messages into a log file or an email ??
  24. I created a custom SOP. Sometimes I can cook it successfully, other times it segfaults. It seems to always segfault after the "cookMySop()" function completes (i.e., outside of the code that I wrote???). When it segfaults, it either gives me one of two error logs, or no error log at all. Here are the two error logs. Can anyone make sense of them and direct me in a direction that I can start to look to debug this?

  25. Hi! My H12.5.xx keep getting this error esp when working with alembic. The icon and stuff will disappear, I need to restart H. Never happened in H12.0 and H12.1. From my limited knowledge, alembic use something related to GPU, right? Is this H12.5 openGL glitch? Or I need better graphic card? I'm on 12.5.408/ .376 Windows 7 SP1 Quadro 600 Thanks!
