  1. Hi guys, I'm pretty new using Redshift as an render engine and I have a problem that I know how to solve. I've created a large column of red smoke, but when I render it always appears an annoying shiny noise. I've tried to increasing samples of all the lights to 8192, the gi sample have the same value and I've also override the volume samples to 16384. The uniform samples are: min samples 16 and max samples 128. What can I do to clean up the render? I've tried to increasing the uniform samples but doesn't seem to show any change and increase the render time a lot. I've attached and image to show you this shiny noise on the volume. Thank u in advance!
  2. Hey guys, I try to export particles to maya with a redshift proxy but when I try to export it, the proxy appears empty. I tried using both the Output Proxy Sop and the Redshift Rop and both give the same result. Is there anyone who know why this would happen ? Cheers,
  3. Hey guys. Any idea how I could get render time displacement, based on values of points that I scattered on the surface? This is a simple scene of what I`m trying to achieve. Basically I have sourceprimnum and uv values on points and I just need to transfer those values to UV maps I think so I could use them in redshift to drive displacement. I tried using geomerty to bake displacement maps in COPs and it works, but original geometry is would have to be subdivided too many times and would get way too heavy for what I`m after. Any ideas how I can do that in render time? I`m gonna use Redshift, but that doesn`t really matter. Cheers Janis displacement2.hip
  4. Hey Guys, after adding a RS camera tag to my camera in Houdini. My ocio fails, it worked absolutely fine before I added it. Plugin Version is 3.0.13 Houdini Version 18.0.0287 Hope somebody can help me, cheers, Lucas
  5. Hi, How to Render infinite ocean using Redshift In mantra Shader Directly read spectra node, but what about Redshift how to spectra in Redshift
  6. 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.

  7. 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
  8. Replicating Coins

    A little experiment I like to nickname: 'Life as a VFX Artist'
  9. 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
  10. Boat Wakes displacement map

    I have boat wakes from Ocean flat tank .Fluid compress and the Surface cache. Exporting to texture at the oceanevaluate node give me the ocean wakes and the boat in black. What I want is only the the wakes from the boat as a displacement information so I can apply it on a grid that already have ocean deformation in Maya ( for Redshift ). Is anther another way to do it? Thank you! This is what I have now
  11. command line problem

    Hello. I`m trying to help a friend to setup a command line with redshift and houdini but I havent be able to do it. If I try using mantra, it works like a charm. But if I try with redshift, it dosnt. Looks like the command line is not loading redshift because I receive this errors: "Skipping unrecognized parameter "Redshift_SHOP_parmSwitcher"." " Bad parent found (parent is not a network): shop/rsMat_env_dirt/redshift_material1.init." and more like that. As extra information, if I run the command hconfig in the command line, I receive this: HFS := 'C:/PROGRA~1/SIDEEF~1/HOUDIN~1.425' HOME := 'C:/Users/machine' HOUDINI_DESKTOP_DIR := 'C:/Users/machine/Desktop' HOUDINI_OS := 'Windows' HOUDINI_TEMP_DIR := 'C:/Users/machine/AppData/Local/Temp/houdini_temp' HOUDINI_USER_PREF_DIR := 'C:/Users/machine/houdini17.5' HSITE := 'C:/PROGRA~1/SIDEEF~1/HOUDIN~1.425/site' USER := 'machine' # but if I run hconfig in the shell from houdini, I get this: HFS := 'C:/PROGRA~1/SIDEEF~1/HOUDIN~1.425' HOME := 'C:/Users/machine/Documents;' HOUDINI_DESKTOP_DIR := 'C:/Users/machine/Desktop' HOUDINI_OCL_DEVICENUMBER := 0 HOUDINI_OS := 'Windows' HOUDINI_PATH := 'C:/ProgramData/Redshift/Plugins/Houdini/17.5.425;C:/ProgramData/Redshift/Plugins/Houdini/17.5.425;&;C:/ProgramData/Redshift/Plugins/Houdini/17.5.425;&' HOUDINI_TEMP_DIR := 'C:/Users/machine/AppData/Local/Temp/houdini_temp' HOUDINI_USER_PREF_DIR := 'C:/Users/machine/Documents/houdini17.5' HSITE := 'C:/PROGRA~1/SIDEEF~1/HOUDIN~1.425/site' JOB := 'C:/Users/machine' USER := 'machine' # I suspect that hrender cant load redshift because is not loading the enviromen variables. We tried with royal render, and it works with mantra. But it fails with redshift. Rendering with redshift from houdini works perfectly. any help would be appreciate. Thanks
  12. Learning Houdini on Twitch.tv

    Hello! I'm starting a twitch dot television channel and will be streaming Houdini training content. I've worked at several large VFX and advertising studios as well as taught Houdini classes at Academy of Art university. I'm hoping I can reach a larger audience through Twitch as well as the idea that people viewing the stream can participate by asking questions and providing feedback in real time. This is my channel: https://www.twitch.tv/johnkunz My first stream will be starting on Sunday (Jan 26th) @ 1pm PST. If you follow my channel (it's free ), you'll get an email notification whenever I start a stream. I'll be going over this project I recently finished https://www.behance.net/gallery/90705071/Geometric-Landscapes showing how I built things (VOPs, packed prims, Redshift render) and why I set things up the way I did. Some of the images I made are shown below. Please come by this Sunday with any questions or ideas you might have!
  13. Hi all! There's 1 week left to register for my Mastering Destruction 8-week class on CGMA! In supplemental videos and live sessions we'll be focusing on some of the awesome new features in Houdini 18, and exploring anything else you might be interested in, such as vehicle destruction. For those that haven't seen me post before, I'm an FX Lead at DNEG, and previously worked at ILM / Blue Sky / Tippett. Destruction is my specialty, with some highlights including Pacific Rim 2, Transformers, Jurassic World, and Marvel projects. I've also done presentations for SideFX at FMX/SIGGRAPH/etc, which are available on their Vimeo page. If you have any questions, feel free to ask or drop me a message! https://www.cgmasteracademy.com/courses/25-mastering-destruction-in-houdini https://vimeo.com/keithkamholz/cgma-destruction
  14. Hey guys, I rendered this with Redshift and I'm having a weird flicker on the right : I don't know from where it's coming, since I don't have it when I render without the foam. I start to think that it comes from the whitewater coming at a high speed from underwater and popping to the surface, but I'm not sure I can't share the file for now, but if anyone has been through this and have a solution I'll be glad to hear it !
  15. I can't rander sparsepyro emission volume correctly,even rename it to density.And I can do nothing for volume. But Old pyro volume rander is correct. Is redshift can't rander sparsepyro volume?
  16. Hey guys, help me out. I, for the life of me, can't figure out what's wrong with my render options. I set up my fire the way i want it to. Viewport looks nice. Then I try to render it as PNG and get this ugly result. What should I check? My Volume option for lights is on. Global Illumination is Brute Force.
  17. Hi ! i'm trying to render particles in redshift. I need to use noise in shader, but the problem is that particles are moving on SOP level and noise also sliding along surface as well In the case of mesh object i just use rest attribute and all is ok. Noise is foxed....but in the case of particles RedShift does not take into account rest attribute on particle.... so it causes noise to move (((( and it seems that we do not have an option to set custom data for noise seed ... it uses only obj position or some vertex data, that particle does not have.... is there any way to get what i need ? to apply bump noise on moving particle and fix it on this particle .... here on picture i have only one particle and it's moving....and bump ((((
  18. Hi. I'm rendering a clouds scene. Redshift log tells me I have 19 unique volumes, How can I instance those? I only have one volume in a geometry node and I copy pasted it another 18 times with different rotations. How can I make those an instance for houdini(redshift) Thank you.
  19. 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.
  20. Rocket launch pyro test

    First post here for feedback and direction, this mostly a test render for my first big pyro simulation. It's being driven by a pop system that's firing particles downwards and using that to drive a pyro simulation. The collisions for the simulation are pretty broken, please ignore those. One thing that I'm having trouble with is getting the outside plumes of smokes to rise higher, anyone got suggestions? Sequence_1_v01_-_converted_with_Clipchamp.mp4
  21. Hi! I'm trying to project a spherical map, an HDRI, onto geometry like so: Can't for the life of me figure out how... I'm using H17.5 and Redshift Any tips or pointers would be greatly appreicated. Kind regards!

  23. Anyone expereinced with lighting and rendering volumes able to offer some pointers? Have a single area light overhead lighting a smoke volume with a simple RSVolume material. Not getting any definition in my smoke. Compare my SceneView on the right below to the render on the left. Is the problem with my lighting or the material or my actual volume? The smoke volume is a narrow box defined by the Smoke object size> .04 wide X 1.5 high by 4 units long. Just trying to get the same detail I see in Scene View.
  24. Hi, While i am rendering with redshift some white dots are appearing. Please help me out to solve this issue. i am new to forum.
  25. So unclear whether this is a Houdini specific error or there is possibly something wrong with my Redshift materials. But when I simply try and cook a ROP Geometry Output node in TOPs I get lots of the following errors Similar to this error but I am not using HQUEUE or submitting to a farm https://www.sidefx.com/forum/topic/69162/
