  3. MultiColored Material

    Hi, Would anyone know good tutorial on how to make multicolored materials like this? It tried it with color mixer note and cell noice pattern , but i doesnt give me a good result , also is there a way to expand the color mixer note to use more than 2 colors? Thanks
  4. Hello! I'm trying to render a flip simulation and I'm getting a lot of flickering. They're all caused by my direct lighting, but decreasing the intensity still doesn't fix it. I've tried to change the sample rate and the rendering limits but I can't find a problem to fix the issue (noise is not a problem but the white reflections). I attached an image with the result. Thank you in advance!

  6. Hello guys, Well i am working on an ocean scene having foam particles over it, I need to render the scene but everytime i put the scene on render it starts using 100% CPU Usage and crashes. Plz tell me how to down sample my render i have 200 frames and not one is getting render. All the render settings are on default and rendering via physically based rendering.

  7. Hello guys, I wanna make an ocean with an ice berg floating over it, I already added environment light, And checked all the diffusion values needed for it but still getting such 2D type of look in my render view i donno what to do now Here is screenshot of my file-
  8. electric shader

    Hi guys, Do you know when i make this kind of electric effect what kind of material should i use? just basic principled shader or anything else? Thanks.
  9. 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.

    HI, any suggestion for houdini mantra online render farm ? i have contacted grid Market. any other ?
  11. matte and phantom?

    Hi guys, I have a simple question. I can't understand when i want to get render in mantra forced matte and forced phantom options. i get render separate every time for example if have destruction scene and if i want to get render that rbd, dust, debris, smoke etc. Do i need to put something forced matte and forced phantom in mantra settings? are they so important? thanks...
  12. HI , I was rendering Ocean using Ocean spectrum and surface, nothing advanced , but I'm getting this weird issue. When I render out in 540p, everything is as it should be but when I render it out in 720p, some parts of it is missing and when I render it out in 1080p, even more parts are missing. So i decided to change the camera angle just for testing, and there it is, everything is perfect, no cutting the edge or anything been noticed, even in FUll HD. I have attached all 4. (in the top view render you can notice the shape of my Ocean, Actually Those are only area i want to render, so ignore the shape ). Please Help me out.
  13. Hi everyone! Just a quick question out of interest. Speaking very generally, fluids usually take longer to compute/sim/render than other types of sim(e.g. rdb). Just wondering why from a technical point of view? Is it anything to do with equations used to compute it? or i guess more particles stuff in the scene? I've just seen how vague and ridiculous this question might sound but any info on this would be really interesting! Thanks in advance!
  14. Hi, I'm searching for a way to create a pointcloud from rendered geometry. More or less it was possible with prman where I was able to save point positions with rendered color information during rendering (or in a pre render pass). Same procedure worked in more ore less in mentalray. Can I do it in mantra as well? The result should be a camera independent point clouds with rgb and position data.
  15. Hello! So I'm not sure if I should be posting this in a Maya forum, but I'm having issues with constrained objects in Houdini. The object was rigged in Maya and then exported to be rendered in Houdini, but when brought into Houdini, on certain frames the parent constraints freak out and cause a weird effect ( show in the picture ) I've narrowed it down to the objects that are being parented. I've tried to delete the constraint and just parenting under the geo, still no luck. Has anyone else ever encountered this? If so what did you do to fix it? Thanks
  16. Hello node friends ! I have a problem in hands here. Basically I'm doing a stadium crowd sim. So far so good. I'm then doing the shading over on the material style sheet and rendering with mantra. I also have a cloth sim with the same proprieties over on that style sheet. The problem I have here is the following: I can render the flags over on the farm with the IFD generation, I've included the SHOPs on the mantra ROP. That part is solved. When it comes to rendering the Crowd, it just renders black. I've tried caching out the results, using procedural geometries and the procedural agent SHOP but it still renders black. I can render it just fine on my machine, when it comes to the IFD rendering part, the machines can't render it. Notice that I have all the agent caches and maps over on a shared network drive that it can access, otherwise the cloth wouldn't be able to render it either. Any ideas?
  17. How to get smoothed UVs at seams in new Subdivide SOP? It was possible in Houdini 16.0...
  18. How can I render animated trail like these from my simulation? Be able to add material to these and do other stuff too if possible. Thank you so much for your help. I succeeded to see these trails in my Dop Import but it shows nothing in renderer (example pic from internet) http://www.sidefx.com/docs/houdini/images/visualizers/volume_trails.png Thank you so so much
  19. Flipbook every other Frame??

    Hello, I was wondering if anyone knew how to flipbook every other frame or every three/four/five frames etc? And if this isn't possible which I'm not sure if it is, how would you go about doing this with a render too? [ without manually flipbooking or rendering every other frame etc. ]
  20. I'm trying to provide an option to render to background so my artists can continue working on their shots Houdini. Currently in my OTL I am calling hou.hipFile.save() then proceed to trigger the render in background option in my mantra rop. hou.node(node.path()+'/render/render').parm('executebackground').pressButton() Despite saving the file, when the render executes, I receive an error telling me to save the file. Is there a better way to approach this?
  21. Hello, I have encountered strange difference in render outputs from different computers and I have hard time figuring out what might cause this to happen. I have created scene on my laptop and then tried to render it on workstation. Both computers have the same Houdini version installed (16.0.736) but they produce different results when rendering. I am attaching both renders - first one rendered on laptop and second on workstation. On second picture, there is strange noise and highlight around area in the middle (exactly where the point light is located inside cloud). I was rendering the same scene and I expected the result to be the same as on my laptop. The main difference is that my laptop is running on Linux while workstation is running on Windows. Also there are different CPUs in these two computers (laptop - xeon; workstation - i7), but I guess that should not make any difference. Please, does anyone know what might cause this difference in renders? Thank you very much. Best regards Trandzik cloud_test_01.mantra1.0001.exr cloud_test_01.mantra2.0001.exr cloud_test_01.hiplc
  22. Hey, When you use the render button in the toolbox, then click view:Mantra, what render node is it using? It definitely isn't using my render node. It renders from the perspective view as expected but its at some weird resolution and not my render node's settings. It renders at 640 x 465, lol. What node is it using and how do i edit it?

  24. Render depth layer but force matte object in the depth layer.
  25. Render ROPs in background

    Hello! I have a question concerning ROPs, because I can't seem to figure out how to render them "in the background" as you can do with other write-to-disk SOP-nodes or Mantra-render-nodes. I really like this options as it gives me the ability to still work in the same scene without having to open another window. My particular case is that I have a flip sim and want to render two caches out at the same time (one fluid cache, one surface), frame-by-frame dependent on each other. If, as I expect, you say that there is no way to do this, because of the dependencies, then I'm fine with that. I just wanted to ask if I missed some usual Houdini-black-magic. Thanks!
