  1. I am trying to render a simulation done with a flip which is made up of 22 million particles. After having made several attempts the houdini console throws me a: 9576: Fatal error: Segmentation fault Saving application data to .... Here below I leave the image and the project files in case someone is willing to help me. Thank you so much!! Help me please!!! Collider.obj Test.hipnc
  2. Hello all, I am on a MAC and was wanting to play around with heightfields but most of the nodes will not work on Mac. The ones I have found so far are the erode nodes and the Slump node. They immediately error including using a shelf tool that throws them down. Has anyone else encountered this error or have an idea what the issue could be? I have attached a screenshot of the error it is throwing up. The Specs on the Mac are below just in case it's helps. Not my personal box. haha iMac, late 2013, High Sierra OS Processor: 3.4 GHz intel Core i5 Memory: 32Gb 1600 MHz DDR3 Graphics: NVIDIA GeForce GTX 780M 4096 MB
  3. hello, Hope everyone is doing well. i have different situation here whenever i save any file in houdini 18 and try to open that file i got this intrinsic error. i don't know what actually happened. guys can anyone help me how can i figure it out this problem.
  4. RS 3.0.13 and RS 3.0.16 tested and both fail. Houdini 18.0.287 Error: Traceback (most recent call last): File "Redshift", line 1, in <module> File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.287/houdini/python2.7libs\roptoolutils.py", line 10, in createRenderNode rop = hou.node('/out').createNode(rop_type, exact_type_name=True) File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.287/houdini/python2.7libs\houpythonportion\ui.py", line 851, in decorator return func(*args, **kwargs) File "C:/PROGRA~1/SIDEEF~1/HOUDIN~1.287/houdini/python2.7libs\hou.py", line 9251, in createNode return _hou.Node_createNode(*args, **kwargs) OperationFailed: The attempted operation failed. Invalid node type name I have absolutely no idea what is going on and I need to get a scene put together to test for work in the next 24 hours. Any clues?
  5. Hi Guys... How are you? I know there is a lot of information there that try to explain why this issue happens. However, I´ve tried to set up a basic scene to replicate the most common problem out there The scene attached is not the final or nothing at all... It was at the point of testing when I'm writing this post HOUDINI COLLISION FLIP ISSUES The main idea is this: Making the inside of the character-filled with liquid (just a little more than half). The liquid MUST be the same at all time. I had to invert signs of the static object to make it "work" And here the magic dust came along. THE LIQUID DISAPPEAR I´ve tried the following attempts with no luck so far: Reduce the grid size to 1 so the voxels of the flips have the same size of particle separation, Reduce the Particle scale to 1 to avoid conflicts in collision Try to multiply the scale by 3 to make it bigger and up the timescale of the solver to match it. I also try to advect the collision field with a volume source with VDB but it was worst and I discard that option in the minute Thoughts: I think it has to be with the particle collision mixture between volumes and particles. For some reason (i think particle accumulation) the solver reaps particles that are very close together and in the next frames, it does the same thing over and over until you are left with no particles at all... I tried to adjust the reseeding and even not reseeding at all and no luck either... It will be SO COOL to finally leave this point crystal clear to avoid future users to melt their brains out Cheers to all Peace! Wolf.rar
  6. Hey my Render View is working absolutely fine but if I wanna render to Disk I always get a short freeze followed by an Error: Error opening the tile device. I’m using RedShift V. 2.6.41 and Houdini 17.5.173 Hope somebody can help me with that.
  7. Hi there everyone. Hope you are all doing well. So for a white now I have had some issues with Houdini 17 and 17.5 fluids. I am trying to create a river sim, but when I cache out my sim using Hqueue or just a "cache in the backgroud", The sim just stops or fails. This morning I woke up and had a Fatal error: Segmentation fault. I am was on windows but it was not activated as I had a huge hardware update but but it could nto find my Linked Windows key or something. I have now switched to Linux and I am currently on Ubuntu. This is my First time on Linux so I do not know what I am doing lol. I cannot even get Hqueue to Restart so I have to reinstall it every time. I tried this one, but it didnt work. My Hardware CPU - Threadripper 2970wx Motherboard - MSI Pro gaming Carbon AC Ram - 128 GB Corsair Vengence LP SSD - Samsung 2TB Please find the attached output log and Diagnostic Info. job_6_output.txt job_6_output.txt
  8. I'm trying to work on a VDB SOP but I'm having problems compiling. I'm windows with Houdini 16.5 and I'm getting "unresolved externals". Along with the usual inclusions I have: #include <GU/GU_PrimVDB.h> #include <openvdb/openvdb.h> #include <openvdb/Grid.h> I'm compiling with cmake which looks like this cmake_minimum_required( VERSION 3.6 ) project( HDK_VolumeDeform ) list( APPEND CMAKE_PREFIX_PATH "$ENV{HFS}/toolkit/cmake" ) find_package( Houdini REQUIRED ) set( library_name SOP_VolumeDeform ) add_library( ${library_name} SHARED SOP_Volume_Deform.C SOP_Volume_Deform.h ) target_link_libraries( ${library_name} Houdini) SET(COMPILE_FLAGS "-TP -std=c++11 -DOPENVDB_3_ABI_COMPATIBLE") add_definitions(${COMPILE_FLAGS}) SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${COMPILE_FLAGS}") target_include_directories( ${library_name} PRIVATE ${CMAKE_CURRENT_BINARY_DIR} ) houdini_configure_target( ${library_name} ) Strangely enough, the program does compile if I don't try use iterators, though I'm sure there is a lot that would break it. I've also tried with Hcustom, but running with that yields the same problems. Does anyone have any suggestions? Thank you very much!
  9. Hello everyone, I am trying to apply facial autorig on a head geometry, but I can't generate a character mask after fitting the polygonal cage on the face. I get this same error on my Houdini console every time I click on the "generate character mask" button: Traceback (most recent call last): File "C:/PROGRA~1/Side Effects Software/Houdini 17.0.459/houdini/python2.7libs\autorigs\modules\advancedFace\advancedFaceGuideOptions.py", line 292, in onGenerateCharacterClicked self.model.generateCharacter() File "C:/PROGRA~1/Side Effects Software/Houdini 17.0.459/houdini/python2.7libs\autorigs\modules\advancedFace\advancedFaceGuideModel.py", line 120, in generateCharacter fxn() File "C:/PROGRA~1/Side Effects Software/Houdini 17.0.459/houdini/python2.7libs\autorigs\modules\advancedFace\buildAdvancedFaceGuide.py", line 156, in generateCharacter self.characterguides.generateCharacter() File "C:/PROGRA~1/Side Effects Software/Houdini 17.0.459/houdini/python2.7libs\autorigs\modules\advancedFace\character\buildCharacterGuide.py", line 122, in generateCharacter self.bakeCage() File "C:/PROGRA~1/Side Effects Software/Houdini 17.0.459/houdini/python2.7libs\autorigs\modules\advancedFace\character\buildCharacterGuide.py", line 173, in bakeCage idx = bs_idxmap.get(edit.name()) AttributeError: 'NoneType' object has no attribute 'name' By the way, this is what my polycage looks like, just in case there anyone notices something I'm missing:
  10. Hello, please help me. I can't get running Houdini 17.0.352 on my laptop (windows 8.1.) After install it was working properly, but after restart, everytime I'll do an object and turn on smooth shaded it will crash immediately (wireframe works). I've tried everything I could: - googling solutions - update all drivers - reinstall houdini - try to install windows 10 (wasn't possible because of my laptop) crash report: Qt Warn: Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use: QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors. QT_SCREEN_SCALE_FACTORS to set per-screen factors. QT_SCALE_FACTOR to set the application global scale factor. 4008: Fatal error: Segmentation fault Saving application data to CUsers/KUBAN_~1/AppData/Local/Temp/houdini_temp/crash.untitled.kuban_000_4008.hiplc
  11. Houdini Pyro OpenCL Error

    Getting an error when trying to run a pyro sim with openCL: "gasturbulence1: Error: compute_turbulence_cl: Error: smokeobject1 - /obj/geo1/dopnet1/pyrosolver1/gasturbulence1/compute_turbulence_cl: Fields must be matching for OpenCL " Any ideas?
  12. Hey guys, I have a quick question about the polygon soup meshes I'm getting out of Houdini. I'm getting mesh popping when I convert it and send to C4D for render, they look like the attached IMGs. I included my set-up in there as a rough guide but I think there's something I'm really overlooking. I'm kinda new to Houdini still and would really appreciate a kick in the right direction of how to solve this in terms of the way I'm approaching 'skinning' the particles. Thanks
  13. Export Quicktime Error

    Hey guys, I'm having a hard time exporting mov files on H17. I can only export avi files and the files are pretty huge. This is the error. Does anyone knows what it could be? Thx Alvaro
  14. Hi, I have a problem with running Houdini since I have my new computer. I already contacted support but could't figure out the problem yet. I hope somebody met with this problem or have some idea for a solution. So houdini is crashing after a few second, I cannot do anything with it. I made some test, seems like it crashing mostly when I press tab and start writing a node. any node. When I just open it it doesn't die instantly, but as soon as I try to do something it just crashes. Doesnt matter if I open a clean scene or open a scene I already have. Recently I got the following error message: 6440: Fatal error: segmentation fault. But in the past sometimes it was just quiting without any message. I had the smae problem since I have this laptop, with H 16.5, but somewhy one of the daily built was kind of working, crashing less frequently, but since H 17 came out I tried that, and it do the same thing. I tried the following things: Reinstalled Houdini many times, different versions, different drives, tried it all. Checked and updated videocard drivers, windows updates the latest (win 10, NOT developer/insider version), cleared registry. Checked Rams, videocard with stress test. and anyway all of the other software running without problem. Also tried turn off every other sofware while running houdini but its all the same. The laptop: MSI laptop with 6core i8, 32gb ram, geforce 1070. So that shouldnt be the problem. I clueless now, I have this problem since months. I would really appreciate any help. Thanks!
  15. Hey everyone, I just downloaded this scene file and am getting a lot of error messages when I try to open it. I've taken some screen grabs of the errors: https://imgur.com/a/oTwmIkV Most of them say "Skipping unrecognized parameter [parm name]" but I'm also getting "[node name] using incomplete asset definition (full definition not found)." Anyone know what they mean or how to fix them? My apprentice version is 16.5.473 Thanks for your time.
  16. ERROR IN VELLUM

    Anyone know how to solve this? I get this in the console : opencl exception cl create program with source
  17. Hi ! I'm trying to setup grains simulation and have faced strange grains behaviour in my setup i'm using explicit constraint with varying strength on all constraints primitives When i run sim i notice that some clumps are moving in very strange manner ! not physical accurate please take a look at attached movie - i've marked piece with red circle...... i tried to set up more substeps but it did not help may be some one could help me to resolve this situation there is the hip file in attachment as well. grerror.mov a1.hipnc
  18. Hello, sorry for my bad English. I had a problem during RBD simulation. Now Houdini does not start this is about the problem. what can i do for this problem?...
  19. 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
  20. 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
  21. 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.

  22. 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
  23. 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!
  24. 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)
  25. 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.
