  1. Hi I am absolutely new to houdini, so sorry for my ignorance. I'd like to give a mist-like shader to my particle animation which made me struggle whole day..... I dropped billowy smoke shader to spheres, and suddenly my particle object wasn't seen in the render view. How can I make it looks more realistic? I have attached my scene file. Help me.........(༎ຶ⌑༎ຶ) +) I think my particle effect is far from the perfect aerosol spray effect, so please feel free to give me some advice to make it better. I'm trying to make it as a volume with a VDB node, but not sure that it is the significant try. Thanks for reading. aerosol spray.hipnc
  2. Hello, I have a render issue. In the renderview the fire looks as it should look but in the final render it appears only on the geometry. Do you have an idea why? Thank you.
  3. Hi, Im trying to create different overrides for diferent arnold render_out nodes, like takes, or like the render setup in Maya, I know I can use the option of use phantom object or matte in the arnold_out node, but is more powerfull to use overrides, it give us the possibility to override more properties like cast shadows, recieve shadows...etc (I dont know this names exactly right now). The thing is I go to out, and I create a node Set_parameter (arnold node) and I conect this to an Arnold_OUT, in the Set_Parameter I create the path for the section I want to override, in this case is an geometry node (selection: obj/geo1/*) inside for example I put a box for testing, and next I write the attribute I want to override, in this case I want to override the arnold parameter from geometry, in this case I write...for example... subdiv_type = "catclarck" subdiv_iterations = 3 ok, this two parameter are working for me, when I activate that arnold rendere node to render, that parameter change and I can watch it in the render, even also work for me this parameter override: matte = True but, and here is my problem, I really want to override the visibility tab arnold parameter, like visibility rays to camera, self shadows an so on...but I cant it work, in this case I write... visibility_camera = False and this last one no work for me, how can I do for this work??? (visibility_camera for example), I only go to the parameter in geometry, arnold, visibility tab and I let the mouse over the parameter, and in the floating window I can watch the parameter, in this case is ar_visibility_camera but I thing for use this attribute we have to remove the ar_ , but event with this I cant get the override for visibility. I let here the official Arnold web site with Set parameter info... https://docs.arnoldrenderer.com/display/A5AFHUG/Set+Parameter Thanks.

  5. Hello Peoples, its my first Time typing in a forum, but i am looking forward to meet the right people here, because in my social area nobody wants to speak with me about Houdini. Haha. As the title says, i want to know how i transfer the pressure/stretch/bend attribute to the final Render Geo and make the Stiffness or the Stress visible in my Rendering. Has anyone a clue? And sorry if there is a topic already. Thanks very much
  6. Hi, I want to use a Mixamo character for a scene. I'm using v18 and when rendering, the render uv cuts/uv seams are visible! I tried in 17.5 and they don't! I want use v18 because the render result is much better. Is there any way to hide UV cuts on v18 render? Sorry for my english and I hope you can help me, thanks in advance. demon.fbx character.hipnc
  7. I left a TOPs network rendering some camera angles, but it's stopped with missing frames in one of the sequences (1-112 where it should be 1-144) Dirty and cook returns done. The caveat is I have 'Cook frames as single work item' on for post-processing nodes (ffmpeg and then some python in this case), when I deselect this I get all the frames and it picks up. How can I get it to check the frames, discover which are missing and pick up where it left off? OR would it be better to let it cook individual frames and then group the output by filename and push that into ffmeg?
  8. Crazy ocean displacement

    Hi everyone, I got a Pretty annoying Problem here regarding an attempt to render a displaced Ocean. So I'm playing with a ship thats comming out of the Ocean (think of pirates of the carebean) and the Memory comsumption Always runs out of Control and causes a crash. Doesnt really matter how low I put the Ocean spectra. I'm testing with a res of 10 and also tried downsampling by a value of 5 in the shader (what should Pretty much turn the displacement into a blobby mess) but nothing helps. Actually only happens when there are a lot of droplets in the air. Running on 80 gigs of ram here. Ist almost as if it goes crazy with displacing each and every drop although its masked out. Also doesnt make sense considering I can downsample as much as I want and it still does this. Furthermore added a mask volume on top of the whole splathing stuff to be sure ist really masked out and doesnt receivve any displacement. Any idea About this?
  9. switch takes and render

    Hello. Im trying to run inside houdini a python script to switch takes and render after every take. It works but it only render the last take: takes_list = hou.takes.takes() for take in takes_list: # if "Main" in take.name(): continue else: print("setting to take: {}".format(take)) hou.takes.setCurrentTake(take) print(hou.takes.currentTake()) rnode = hou.node("/out/Redshift_ROP_CHAR") rnode.render() what`s the problem here? thank you.
  10. Hello people! I'm currently trying to render pyro exoplosion with the motion blur in Redshift and I didn't succeed with any of my aproaches. I tried Convert to VDB , and then Merge Volume in Velocity mode with the motion blur ON but nothing works yet. I found few HIP examples but they neather don't work. Is there anybody who ever did this? Too bad there's nothing about it in the Redshift official documentation too. Please help
  11. How could we achieve something like that? I am genuinly interested on this technique. masking the effect, proyecting the texture, displacing the volume thanks
  12. Hello Houdini folks! For first let me wish You happy new year! And for second, let me have a tiny question . How can I render in Redshift transparent background png. with hdri lighting (RSLightDome)? Is it possible somehow? Thank You very much for any advices. And finally, can I kindly ask U, to post a hip. file, or print-scr with this "transparent-background" preset in your attachment? Many thanks Michal.
  13. Have a bit of a challenging (for me at least) lighting and rendering challenge. My glass is in the shape of an inverted pyramid that is partially filled with liquid. The glass will be rotating back and forth to move the liquid inside. Would appreciate feedback! I know that my meshed liquid should slightly overlap the glass "walls'. Also I am assuming my fluid meshing is wrong in that the sides should be perfectly smooth, not rough as they appear in the attached. I am using a single HDR dome light. What are some other rendering and lighting tips when doing liquid in glass?
  14. How to remove points from render

    I was following a tutorial from @librarian (a nice dude) but i stepped on the following problem: the points render and at sop level appear. I have everything exactly the same on my proyect as the tutorial and still they appear on sop so they end up rendering It should look like this: My proyect grilla3.hip Model solu2od.hipnc Thanks a lot
  15. Next to each other, a comparison between a detailed terrain in the viewport and terrain in the render that lacks so much detail it's almost another terrain. In the screenprint I show the geometry tab in the render section of the terrain. The terrain has been converted to polygons. Why do I loose detail I already have in the viewport?
  16. Hello; In Mantra, is it possible to render a region, in sequence? Thanks.
  17. Hey everyone, Whenever I go to the render viewport in Houdini 17.0.352 I get the following message "Error : failed to save output to file "traceback (most recent call last):" I joined here both the error message I get when I start Houdini and the Message I get when trying to render using mantra. BUG report.pdf Trying to render a frame manually (save to jpeg) also leads to an error. I tried reinstalling Houdini or even deleting preferences but none of this worked. I believe this is a bug linked to Python, but can't figure out what exactly. -- Could you guys please help me with this situation ?
  18. Hi all, I'm rendering some jellies, in water, in a glass tank. Any pointers as to how to optimise this? My render times are huge. Using mantra.
  19. Hey guys, I have a question about rendering and baking AOVs with Mantra. From the extra image planes I managed to render out LPE planes such as beauty, direct diffuse, indirect diffuse, direct glossy reflections, and glossy transmission for a hair groom. They turn out great. The problem is when I try to bake those same image planes from the hair groom onto cards. The LPE image planes come out black. If I try render any of the other image planes like root to tip color, hairID, transparency, diffuse unlit color or any other custom passes, those come out great, but all the LPE passes don't render. I suspect this has to do with the absence of a single camera point, so specular reflections, transmission, and other camera dependent BSDF functions don't produce anything. Is there a way around this? Is there a way I can feed a fake camera/eye point in space to the hair shader and then bake that lighting on a card? In a way to create a static fake incidence angle that references a camera I am not actually rendering through? I am also experiencing problems setting up ambient occlusion to be baked from the hair onto cards, a tip on that would be most wellcome. I am using the bake texture ROP. any feedback would be most appreciated, cheers
  20. Render Smoke Question

    This might be a strange question. I have been learning about rendering the smoke. I went through some basic tutorials to get a final render in mantra. The main one I followed was about transferring the attributes from the viewport shader settings to a mantra shader. I managed to get a good result in one file as far as a good opacity and subtlety. The problem is that if I try to recreate the look in another file I can't find the key attribute or setting I tweaked. Here is the file I had luck with. Maybe someone with a little more experience might be able to help? Thanks, renderBase.hip
  21. Normal Map

    Hey, ist quite some time ago I used Mantra to do some Rendering but for a Project I'm working on atm I like the more realistic look it gives me compared to redshift. So with redshift I'm just plugging in a normal map and it renders just fine. Trying to do the same with a classic shader but I just get a corrupted Image. Cant see any place to manually plug in Utan and vtan. Something I'm missing?
  22. I am trying to use the color visualizer to colorize a topographic map, it is all working perfectly in the scene view, however, the render in Mantra is not picking up those colors and the render is only a single base color. Anyone could help how this can be done? Appreciated Khal
  23. I have 3 entries in a wedge (each 48 frames) that I would like to render out in 3 different videos, instead of render all iterations out in one video. How can I do that?
  24. Hbatch "killed"

    Hi guys, I've recently (finally) started to use hbatch for rendering/saving out my files and it's a blessing. So far everything has been running smoothly but last night one of my renders died on me. I tried a slightly higher sim resolution and started it before leaving work, when I returned this morning I could see that slightly less than half had been simulated and real fast, only about 3-4 minutes each. But then I simply got the "killed" feedback in my terminal with no further information, even though the render command was set to verbose. Is there someway I can access why it was killed? Since they were running so quickly I don't believe the system ran out of resources but then again it is fully possible. / -> render -V obj/PYRO/explosionVdb Rendering 54 frames ( from 1 to 54 by 1) 19:55:47 explosionVdb frame 1 (1 of 54) 19:55:47 explosionVdb frame 2 (2 of 54) 19:55:47 explosionVdb frame 3 (3 of 54) 19:57:18 explosionVdb frame 4 (4 of 54) 19:58:15 explosionVdb frame 5 (5 of 54) 19:59:34 explosionVdb frame 6 (6 of 54) 20:01:37 explosionVdb frame 7 (7 of 54) 20:04:52 explosionVdb frame 8 (8 of 54) 20:08:23 explosionVdb frame 9 (9 of 54) 20:11:32 explosionVdb frame 10 (10 of 54) 20:14:48 explosionVdb frame 11 (11 of 54) 20:18:12 explosionVdb frame 12 (12 of 54) 20:21:46 explosionVdb frame 13 (13 of 54) 20:25:28 explosionVdb frame 14 (14 of 54) 20:29:17 explosionVdb frame 15 (15 of 54) 20:33:19 explosionVdb frame 16 (16 of 54) 20:37:32 explosionVdb frame 17 (17 of 54) 20:42:00 explosionVdb frame 18 (18 of 54) 20:46:43 explosionVdb frame 19 (19 of 54) Killed I'm running Houdini Indie 17.5.258 on Linux Mint 19.1 Cinnamon.

  25. Hello guys! Can I ask U question, Im very new in houdini. Can u help me please? Im trying to render short video of volume (smoke) in matra, but I really do not know how to set the mantra settings, because one frame is mantra creating for 43 minutes, which is rediculously long time for 250 frames. can U help me, with settings? I already increased the Volume step size, but thats all what I did, (I read somewhere its helpfull) is there any other way, how to make render time (per frame) shorter? Thanks a lot for any advices! Im looking forward to your re´s! By! advice.hip
