  1. 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!
  2. 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
  3. 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 !
  4. 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?
  5. 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.
  6. 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 ((((
  7. 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.
  8. 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.
  9. 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
  10. 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!

  12. 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.
  13. 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.
  14. 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/
  15. Hello, i want to control the emission of new born primitive using pscale attribute in redshift like this im able to do it on mantra using bind node but how to do it on redshift..? torus_Odforce.hip ODforce.mp4
  16. Hi, I'd like to get some help from you, because I ran out of ideas. It's about Redshift proxy and instances. I'd like to make forest with different colors with the "RSUserDataInteger" in the Redshift Material in shop network. I tried with the simple box example, and it worked. However, when I use the material override in different ways for the proxy trees and it uses only one color, so I cannot randomize colors. I attached the hip file and proxy tree for you to examine. Thank you in advance! switchShaderTest_02_v003.hiplc tree_01_v01.rs
  17. Hi ! I've got hqueue farm set up on linux machines. i use it only for simulations Sometimes i get hip files for simulation that contain various number of operators which are not needed for sim (i.e. some custom ROPs, materials etc.) BUT ! when a client loads this hip file it warns that it can not load specific OTL and refuses to load hip. Let's say i have a scene with geo node that has reference to some Redshift material in its 'material' parameter. but i don't want to render this. i just want to simulate and write geometry to disk. But hqueue refuses to do that because it can not find redshift otls .... Is there a way to force houdini to ignore things like this....????? So you can not find otl!!!!....nevermind. just simulate...you do not need redshift to simulate dop network.... upd: when i connect to client via ssh and start hbatch in terminal - it works.....it loads file, claims that can not recognize node types...but simulation works when i start it with the command manually (render -V rop_node).. why hqueue can not do that and just fail the job ???
  18. Hey, Anyone else having an issue with 17.5.258, where redshift 17.5.229 rendering works fine... but my flipbooks (Mplay) crash? I can render with Mplay but when I go to flipbook anything it leaks mem and them flipbook crashes saying it can't display images. If I remove the env variable pointing to the taskbar, flipbooks work? if I use an earlier redshift plugin version (i.e. 17.0.506), the self and flipbooks work fine... but there isn't the same functionality. There doesn't seem to have the RS proxy output. Please let me know if you have run into this or an issue similar. Thanks
  19. Houdini - Redshift - Deadline

    Hey guys! I'm trying to setup deadline for a couple of machines for rendering in houdini with redshift. Deadline setup is ok. Caching and mantra rendering jobs finished successfully. When it comes to redshift job, deadline also receives it and distributes. But the rendering process happens very fast and there are no render output files in the output directory. Also while deadline saying that the job is rendering the video card doesn't seems involved. Did anyone have a chance to encounter such kind of problem. Any help appreciated.
  20. Abstract Visuals - Houdini and Redshift Link: http://bit.ly/2ZFfdti This course is about the creation of visual abstract effects in Houdini. At the same time, this course is also about Redshift for Houdini. Things we create together: abstract lines, geometric shapes, crystals out of this world and an ornametal structure. At the end of this course we are going through a pdg pipeline for redshift. I'm looking forward to the course! See you in the course! Tim
  21. Hi. Need help ! I am instancing redshift proxy object (Human character with primitive groups like shirt, pant, skin.. etc ) using "instancefile" attribute and using stylesheet to render it. I am not able to access subtargets and randomise any material parameter (like randomising basecolor of subtarget shirt or pant). I am able to do this using mantra and stylesheet but similar approach (targets and subtarget) is not working for redshift. In the stylesheet, the Target is set to point instances; I tried accessing primitive groups on the instanced object by adding subtargets to the target but it does not work. Can someone please help me with this. Thanks
  22. Redshift issue with pyrofx

    I'm trying to render an explosion and here is the result ? any idea ? thanks hdni_untitled.hip
  23. I'm trying to instance simple sharp rectangular geo onto scattered points to create a frost effect. I've tried 3 methods: - The copy to points sop (w/ pack and instance) - Adding the s@instance attrib with a path to the geo - Using the instance node at obj level When rendering with around 1000 points I get a decent preview quickly in the IPR but a full render at 256 samples still takes far too long. If I try to up the point count to something like 50k, I struggle to get any feedback from the IPR. If I go to 100k I get no feedback in the IPR, it just freezes. When I try to render to disk, the render doesn't even begin. What am I doing wrong? From what I've seen I should be able to achieve 100k instances fairly easily if I'm not mistaken. I appreciate any help! Specs: i7-6700k, GTX 1080, 16GB RAM
  24. gradient r&d

    Hi all, I'm approaching something in H/Redshift which I've not really attempted before - So was interested to see if there were any thoughts surrounding it. Basically I'm trying to recreate the soft/feathered gradient seen in the attached ref image. The inner hard edge I'm planning to achieve with some transformed geo floating above the grid below, however the super subtle feathering is challenging me a little. At first I though of using a simple attribVOP on a grid > point Cd. However I'm nut sure how to achieve the outer feather using that technique... Similarly with an attrib transfer from geo > grid it seems not very feasible to get the extreme feather unless the mesh is crazy high res? I'm continuing to experiment & look through forum threads, but if anyone has some suggestions/tut links/examples etc. would be very much appreciated! (Worth noting system = H17.5.258 & RS 2.6.43) Thanks in advance!
  25. Hey, i am fairly new to houdini and especially to redshift. I have a setup with particles and want some particles to be emitted by a specific distance. I use the particle color as base color and want my attribute to drive the emission strength. If i use mantra everything works fine. Couldnt find any solution. Cheers and thanks, dom
