  1. When trying to put a guide simulation on my fur, houdini starts cookingOP and after 1 min 30 sec it gives me the error : "memory allocation error occured, probably duo to insufficient memory" and crashed. Anyone knows how to solve this ? Kind regards Specs: CPU: Intel core i7 16 GB ram GPU: Nvidea quadro m2000m houdini 16.5.323
  2. When I do some simulations like pics at bottom, Scene view become crazy like those .. I imported alembic files and set their position. but If I do simulations with dopnet, They are gone to randomly strange position like secone pic, and going to be black like first pic. When I delete scene view and make it new, It looks like when I set up. But I have to see that simulations preview and these problems make me crazy :S Help me with this plz !! Sorry for my poor English and thanks for read Have a good day
  3. Hi!! I'm a VFX student new to Houdini and i'm having some problems to render a "stone" shader because some of the stones in my displacement show some kind of glitch / flicker. I'm rendering in mantra in a 3-5 samples setup, I've tried to put normal node and it make the same error. My shading setup for the displacement is "Zbrush displacement map + 2 stone textures with some fits + uv noise + uvxform, all of this connected to color mix that goes to displacement" my zbrush displacement is 8k resolution in tiff.

  4. Hey, Anyone else notice that turning on open cl in pyro solver creates an error after updating to houdini 16.5? All you have to do is use one of pyro's presets on the shelf then turn on open cl. Is this a bug or is there actually something wrong? thanks
  5. Voronoi inaccuracy (R16?)

    Hello all, I'm using the pre-fracture transform method (following this Lester Banks video, specifically) to roughen up voronoi cuts. I feel like I've done this before without a problem, but now I'm discovering some little quirks in the form of misaligned points after cutting (see attached). Increasing the mesh resolution helps; it's even good enough, but in some cases it never goes away--some points that should share the same position are a little offset from each other. This is present even on my test setup with only a sphere, Attribute Vop to apply noise, and the Voronoi Fracture. Has anyone seen this before? Surely it's come up, but I couldn't find previous posts. Thanks! PS. The place I'm currently working at has Houdini 16--that's not it, is it? (I only ask that because it's the first time I've used 16 and I feel like I would have seen this behavior before.) Increasing the mesh's resolution and changing the Scatter seed until the problems aren't very visible has made it good enough, but I'd still like to know what I'm doing wrong/if there's a way to prevent this in the future. Thanks again!
  6. Hey everyone, I'm working on a Houdini 14 scene that I've opened in Houdini 16. I'm slowly converting the node network over to the latest versions and I'm getting "bad parameter reference" errors on a lot of the nodes. It's popping up on both the old and the new nodes. Does anyone have experience with this type of error and how to resolve it? I've tried googling and looking around for similar issues online and I havn't had a lot of luck. Thanks! Chris (AUS)
  7. 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
  8. "Exception happened" - Python error on start up

    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.

  9. 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
  10. 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
  11. 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)?
  12. Vertex Animation Tool giving mantra error

    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
  13. 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)...
  14. 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
  15. HQueue unable to open file

    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 15.0.244.16\houdini\scripts\hqueue\hqlib.py", line 1489, in simulateSlice controls_dop = _loadHipFileAndGetNode(hip_file, controls_node) File "C:\Program Files\Side Effects Software\Houdini 15.0.244.16\houdini\scripts\hqueue\hqlib.py", line 331, in _loadHipFileAndGetNode _loadHipFile(hip_file, error_logger) File "C:\Program Files\Side Effects Software\Houdini 15.0.244.16\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...
  16. 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!
  17. 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
  18. 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!
  19. 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
  20. 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
  21. [SOLVED] H15 crowd simulation error

    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
  22. 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.
  23. crowd render error

    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!
  24. 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
  25. 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.
