  1. 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.
  2. Hey everyone! I've been digging through the forum but quite haven't found something that will help me get this effect i'm trying to achieve. i'm trying to work on an setup where I have particles stuck on a deforming grid and the particles become unstuck as they inherit velocity in Y(sop solver) and then with gravity they come back down. my current setup might be too complicated because it's proving very difficult to control. i am using a popnet where particles stick to the collider geo and become unstuck with a sopsolver "if (@Cd.r > .1){ @stuck = 0; }" does anyone have ideas on how to simplify the setup? is this something that the grain solver would be better at handling? thanks everyone! waveRipple_v003.hip
  3. I would like to have the same Redshift Light setup from Maya, in Houdini. First I created a simple Maya script that copy's the RSlight attributes like intensity etc and places it in a .txt Now in houdini, I want to create RSlights on the same position, with the same attributes. The text file will look something like this '''[rslight1(x,y,z, 100 # intensity)rslight2(x,y,z, 50 # intensity)]''' How would I approach this in Houdini? My thanks
  4. Hello; Poly-Bridge SOP connects edge-loops automatically, but I want to pair them manually. Is it possible? Thanks for helping. PolyBridge.hip
  5. Hi; In VEX, I want to select boundary edge loops, based on a points group. Here is my point wrangle codes: int Array[]; if(inpointgroup(0,"PointsGroup",@ptnum)==1) { append(Array,@ptnum); foreach(int ix; Array) { int ShEdges = pointhedge(0,ix); if (hedge_isprimary(0,ShEdges)==1) { setedgegroup(0,"SelEdgesGroup",hedge_srcpoint(0,ShEdges), hedge_dstpoint(0,ShEdges),1); } } } The problem is, it selects only some edges like image bellow. Any ideas would be appreciated. Thanks BoundryEdges_01.hip
  6. VORTEX FORCE FOR VELLUM

    Anyone builded a vortex force for vellum? or maybe had a idea how to? thanks Tim
  7. Hi, This is giving me headaches for two hours now.I know it would be much easier in vex,however I dont know how to achieve this effect. If anyone can please point me in the right direction that would be greatly appreciated! There are some arrows shoot into ground in this scene,I want to make some small crushed stones in the first catch point. But the question is how i can get the one primitive source in just one frame? Transfer color is the best way i can think whitin my all power. Let me show you some GIF shot204.hip
  8. Ran into a problem when caching out my high resolution fractured geometry. Each time I try to save to disk it stops every time at a certain piece and crashes each time. I think the problem lies with the SOP Cache memory being too low at 1024 max, however, the option to increase the Max is always greyed out. Any ideas? HouseSim0015.hipnc
  9. COLORED NOISE GROW

    I am new to houdini and wanted to ask how Tim van Helsdingen grow this color from minute 9:50 ? The Youtube link :
  10. I can't take credit for it, but it needed to be shared. This made me cry with laughter.
  11. Hi everyone, H17 was just released and with it finally houdini engine (indie in my case) for 3dsmax. I have tried to take it for a spin using the preset hda it comes with, obvious one to test is the boolean as houdini is amazing at that and 3dsmax far from. it works wonders if I make a simple box and a sphere, but as soon as I try to add a more complex model, 3d scan or anything else that I have used many many times inside houdini before, it crashes max to desktop instantly. just wondering if any of you have this experience too? Cheers,
  12. Hi there everyone, Hope you are well. So I have been getting some advice from Industry Professionals about building a reel and I have been watching a lot of Houdini industry live streams and a they all say the same thing, CG with plates or tracking your shot. Now I am very new to the FX side of things and I am progressing well with Houdini but I am not sure how things work on the Comp side other than the basic channel manipulation in Nuke and separating out your render layers in an exr file but anyways. There are going to be a lot of questions coming up, I just want to really understand how things work. So I know with tracking you place little markers on the ground (I.E a piece of paper with an X on it lets say) and then you can track that with a Software. Now what I want to know is what is the difference between Tracking and 3D tracking or is it the same thing ? With Plates, is it just taking a picture of something, Cleaning it up in comp and comping in your CG element or is there tracking involved as well ? I know there is things like lighting involved which you can match by eye I guess but is there a good way to do lighting ? Another question is what are good softwares for tracking or Plates ? I know there is after effects but I have also heard of Boujou and Syntheys or something. Any advice would be really helpful. Thank you in advance and have a great day. Jody.

  15. Hi, Recently I had to develop a method for Alembic Sequence files export from Houdini and Load Alembic Sequence files in Maya, I couldn’t find any solution for this problem at that time, so I decided to develop some Python script to do these tricks. Below you can find my tutorial and source files for abc sequence files Houdini to Maya. Hope you find this useful in your workflow. If you have any questions or anything feel free to replay here. Thanks, Mahesh MS. HELP_abc_sequence_files_Houdini_to_Maya.pdf abc_seq.zip
  16. vex deform wave

    Hi there, Trying to deform a wave geo with a hand, it works on a sphere (sort of) but doesnt work with any other geo. what I am basically trying to do is to have hand coming out from a wave with one very same piece of geo, that is it. Thanks wave_hand_deform_help_v001.hipnc
  17. Hi Guys! So i'm trying to do this simple flip sim where i have an emitter inside a teacup and i just want to fill up the cup. It's is definitely water tight, the only particles leaving the cup are over the top, but as you can see from my flipbook the particles just start multiplying on their own when they land in the saucer, which is causing them to go everywhere. It is worth mentioning as well that the particles are only set to emit between frames 0 - 24 so i'm not sure why they're multiplying. Any suggestions as to how to stop this would be really appreciated!
  18. Hey, iam using a simple glass material with some tweaked parameters and i rendered out one single frame, it took me 1.5 hours to render it complety and i still got a decent amount of noise? Im using a hdri image for lightning and increased my samples from my lightsources to reduce noise. anyone would know how to reduce my noise? This are my render settings.
  19. hi i am trying to chive independence day resurgence alien rival to moon. i am trying to do in particle driven pyro and custom driven pyro. but not working properly. any one please help guive an idea to achive this effect. i am attaching some screen shot.
  20. Lately I have been trying to wrap my head around transforming point positions with the use of matrices in VOPs. To do that, I tried the following: Lets assume I have 3 points with their position vectors A, B and C which come from an alembic and are constantly changing values. I use a time shift and set it to $F + 1, and extract the same points position vectors, which are now called D, E, F. Then I set A,B and C into a 3x3 matrix, transposing it (to get the vectors in columns instead of rows) and do the same with D, E, F. After all this, I multiplied the inverse of the matrix containing ABC with the one containing DEF (this was not inverted). The resulting matrix was multiplied with new Position inputs, but the resulting transformations didn't match the original ones... What am I doing wrong? Thank you.
  21. Hi Everyone I am trying to replicate the output of this tutorial in houdini which was done in 3ds Max by Allan Mckay i am trying this thing in houdini since weeks but i am no way near to that......... A little help would be appreaciated!!!!
  22. Hi forum. I am trying to export simulated curves from Houdini into Maya using Alembics so they drive the XGen anim curves. I have exported curves from Xgen into Houdini and connected them to the 16.5 Hair System and simulated them. The problem is the Alembics from Houdini are exporting all the curves as shape nodes under one curve, instead of exporting each curve separately. XGen's Anim nodes wont read these. Does anyone know how to export curves from Houdini into Maya with Alembics without them packing?
  23. Laptop for houdini

    Hello guys, I wanted to ask for a suggestion for a good laptop. I won't work on Houdini everyday, so it's mainly for sometimes uses, and also be able to run it/simulate something (not too heavy). I know a workstation would be better, but I am travelling too much right now, would be impossible.. Dell 15.6'' ( this one cost 150 less) Intel® Core™ i7-8750H Processor RAM: 16 GB / Storage: 512 GB SSD Graphics: NVIDIA GeForce GTX 1050 Ti 4 GB Razer Blade 15.6" Intel® Core™ i7-8750H Processor RAM: 16 GB / Storage: 256 GB SSD Graphics: NVIDIA GeForce GTX 1060 6 GB I know the specs in the sidefx website says min GTX 1060, but maybe the 1050 ti will do fine as well. or not? What do you think between those two? Or do you have any suggestions for around the same price? Thanks!
