  1. Hi, In H18 when a node ( which type is a digital asset ) is duplicated this happens: Any Ideas? Thanks in Advance !

  2. The constraints seem to be broken in Houdini 18.0.532. I followed the regular workflow for building constraints for a regular rdb simulation. But they don't seem to make it to the DOP network. There are no errors, but the constraints don't work (They don't appear in the dopnet). Can someone please confirm this? Thank you.
  3. I just downloaded Houdini's free version for the 1st time, and it does not look like as in the youtube videos or other places where I saw it. So it looks like that: and i don't know why. I deleted Houdini and install again and again and it is looks like this again and again. Please help me.
  4. Problemn using Point Deform

    Hello everyone ! I would like to deform a geometry by a fluid simulation using a point deformer. To do so, i plug my geometry and my simulation into my point deform and i use a Timeshift set up on the starting frame as the Rest PointLatice. But instead of following the simulation, it looks like the geometry tries to reach the world center, creating what looks like an unholy abomination. Any help or tip would be deeply appreciated Thanks in advance
  5. Hi, I was following this tutorial but at around 5:20 he started using green guides to select and move individual guides, which I dont get. Im using 17.5.425. Does anyone know what's the issue or if it is a bug? Thank you
  6. Hi guys. I can not understand what the problem is. When I try to render the geometry on the point Houdini falls. I tried Houdini 17.5.173 and 17.5.229 and 17.0.459 (but this version cannot read the attribute “s@instancefile” and simply hides the object and does not fall). I also tried Redshift 2.6.39 and 2.6.40 I also checked on 2 different PCs wits RTX2080 and GTX980m In this case, the mantra makes the render right and does not fall. https://monosnap.com/file/ALqgtmx3qCPtmEu1cq4XKcKH3S1a8D Box.bgeo.sc *UP* *FIXED* the problem was in its node instance it was necessary to switch to display only mode.

  7. How would you auto-magically remove the trailing "1" after an instance of a custom OTL? It seems like there should be some on-creation script location, somewhere...
  8. Tried to export a heightfield of a terrain in greyscale using cop2net and sop import but I get individual elements (height, water, debris, sediment...). 1. How do I get the full terrain out of it? 2. How do I even get these individual elements out? You've guessed it, I'm new to Houdini.
  9. Anyone here had troubles before with importing a heightfield HDA into UE4 that only shows when selected? It seems random, sometimes it doesn't behave like that, I don't understand where the bug is coming from. I can solve it temporarily by going to the manage tab for landscape and the change component size option and not change anything and click apply. Except it will move the landscape out of my HDA, and this breaks my pipeline. I got it to work perfectly sometimes, but I don't know how, it just seems this problem is random.
  10. Hi, I have a strange behavior with the auto Rig Tool in Houdini 16.5 If want to create a Asset it just creates 3 helpers and a merge node and I´m not able to add a Head / Arm etc. In Houdini 16.0 it works fine....Anyone else noticed this behavior? I attached a screen capture to demonstrate. AutoRig_Bug.flv
  11. Hello, i am currently working on my final student projet where i make a plane crash with Houdini. I base the workflow of this project around the RIGIDS III tutorial by Steven Knipping. Everything is working fine until i bring in a simple glue constraint, and when the simulation gets activated at a said frame the simulation simply does not happen. It works when i disconnect/disable the constraint. I already tried to unpack the alembics upon importation with the alembic node but that didnt change anything. What is weird is that everything was working fine when i used the model given with the course. I haven't really found anything that helped me online, so hopefully one of you can help me with this issue, i would appreciate it A LOT. I will attach the files down below. Thank you ! plane_sim.rar
  12. Houdini FEM stops at frame 800

    I am trying to sim a 1000 frames of a FEM coral with branches swaying in water currents. For some reason it freezes at frame 800. I checked all the DOP nodes, and couldn't find anything obvious. What am I missing? softCoral.FEM.paintWidth.h16p5p378.v27.hipnc
  13. I don't usually meddle with functions in VEX, but today decided to give it a go since I wanted to have some functions being used by other functions. I'm having issues calling functions inside functions. The code below for example will trigger errors. float foo(float a, b) { a = clamp(a, 0, 1) ; return a + b ; } float bar(float a, b) { return foo(a+.1, b+.1) ; } And it can be "solved" in multiple ways: If for example I comment out the clamp part it passes: If instead I remove the +.1 from foo it works as well. I have other examples where such simple corrections and the multiple corrections don't work or are not straightforward so what I'm after is understanding what's the main cause of this. Either I'm missing some method here ( I did try C++ style declaration / definition) or maybe there's some issue with calling a functions from a function. Cheers PRB_RFE_VEXFunctionCallBug.hiplc
  14. Hi everyone, I'm a bit confused right now because I have a weird issue on my Houdini when I work on Alembic. I have some huge (not that huge, but still) models in Alembic format and I want to do VFX stuff on it. But I can't have a proper feedback on my viewport when I do some operations on it. As you can see on the gif capture, the color does not appear in the viewport, but if I save the scene, and open it again, the color appears. I checked my graphic cards driver (I have a GTX 970), and everything's on date, and I'm on Houdini 16.0.621. Is there a solution ? Thanks in advance, Gael. EDIT : Even if I launch Houdini as Administrator, the bug still appears. I need help :<
  15. I'm trying to set up a structure that allows me to import 2D images, PNG/Jpegs into Houdini. Side FX has documentation for this: http://www.sidefx.com/docs/houdini11.0/io/ai Researching this i came across a couple of tutorials, saying that if you want use images you should go for .eps files This is the tutorial i tried to follow, since it covers the Adobe softwares: I'm not sure what's going wrong, whenever i upload my images there doesn't seem to be an error, but I just can't find my imported asset. Any ideas? Cheers, Callan de Keijzer Desktop.zip
  16. Hi, can anybody confirm or invalidate my suspicion that op: expression in shaders context (mat or shop) cuurently doesn't work? I know syntax has been a bit inconsistent between different Houdini versions but right now in 16.5 it doesn't seem to work at all for me. i tried: op: /obj/copnet/OUT op: "/obj/copnet/OUT" "op: /obj/copnet/OUT" op:`opfullpath('/obj/copnet/OUT')` and many other mutations of the same thing. anybody? thanks, D. file attached just for case copReferencing.hiplc
  17. POPsolver not working

    I'm trying to source particle emitters from geometry that i created in a scene. Unfortunately, there seems to be an issue with the popsolver node, it's saying that: 'Connection 2 input is the wrong type' I'm trying to create a whisp effect, following some tutorials but already stuck and not able to continue. Please help! WhispIssue.hipnc
  18. Hello everyone,I encounter a problem, I load an object in my scene. I noticed that my shift in the viewer did focus my object, so I searched on the sidefx helpers (I link the url) "http://www.sidefx.com/docs/houdini/basics/view [www.sidefx.com] “The solution I could find was the ”space + G".He walked once.Arrived at a certain level of my work, I had to use the procedure previously done.I come to my big problem.My object disappeared, leaving room for red stripes on my node geometry. I can not find where the error came from … it is not for want of having tried yet. Do you have solutions? I link you my project and the picture of the problem.Thank you in advance Pyro Smoke_v03.hip
  19. Hello!I am having a few bugs with the houdini toon shader.In some scenes it appears as though there are two objs on top of each other and intersecting, when there is not. Also, some parts of the model are just black under lighting while others are not.Has anyone come across this? If so does anyone know any ways to fix this? Thanks
  20. Hi, I have some issues with the FUSE before SUBDIVIDE sop and I think it might be a bug. Its realy simple... -> Platonic Soccerball -> create Unique Points -> assemble name attr. -> (foreachSubnet.-..Extrude) -> Fuse -> subdivide. After that it just doesnt seems to work probably. see example: soccerball tst.hip
  21. Houdini hair problem

    Hi everyone I just recently started playing around with Houdini hair after finishing a very difficult job done with Yeti. I am trying to assess houdini hair as a possible new solution for hair and fur. But I have one small issue that I cant find any solutions for it: Basically after setting up the fur for the model (I am using the Add Fur tool from the shelf) everything is fine and I can use the different attributes like length and bend to adjust the overall look, But as soon as I groom the fur using one of the shelf tools like "length adjust" or "cut hair" I cant tweak the overall attributes like length or bend etc anymore and it seems like after grooming the hair using any of these tools I lose the ability to adjust the overall attributes. I was wondering if this is probably a bug in hair tool? I have attached my test scene as well. I would appreciate any helps. Thanks in advance! Sina fur_pipe_test_01_v01_t05.hip
  22. Anyone have this strange problem exporting particles from Houdini to Maya?It doesn't happens on all frames,its just sort of random,some frames render fime if you turn off snapping in timeline and scrub,weird. The render engine its Arnold,i know there is a way to carry the v information in vertex to Maya But this its the only way to avoid this issue? The particles are geo after a copy operator,nothing fancy
  23. So before I submit this as a bug I just wanted to see if anyone else on here might have experienced the same issue. Houdini Version: 14.0.444 Step 1: Read in an animated cache (from wherever, doesn't matter) Step 2: use a split node to break something apart Step 3: plug the output of the righthand side of the split into a timeshift Step 4: Does the timeshift do anything? I have recreated this several times already. Every time I read in a cache (I've tried with many different types of caches), split something and try and use a timeshift on the right hand stream of the split, it does not work. Maybe this is a version specific thing, I haven't tested the latest release of 15 with this, I'm just curious if anyone else has come across this. Thanks -N
  24. I have an artefacts after rendering on the tea and under tray @@ help me please
  25. Hi all -It seems that none of the Fuse points options in the Extrude SOP has any effect- I recall the fuse points option, when set to "clamp all points", would clamp the edge that's extruding away from the source (green in top view) when that leading edge(red) encountered another expanding edge. When functioning & the extrusion continued, the setting would result in a poly similar to the blue line in bottom view. Am I missing something? D
