  1. Hi all, I want to import a particle simulation from houdini to Maya without using the Houdini engine and render in Redshift. I made a way around it stamping spheres into particles and exporting them as Alembic, but the file is too damn heavy. Do you have any suggestion? Thanks in advance.
  2. I understand the relationship between Unified max samples and so called 'local' samples. And the importance of keeping Unified samples less than Local samples. But what I find confusing is the relationship between BF, material and light 'Local' samples. Which takes priority and is there a recommended sequence of steps when reducing noise?
  3. I can't figure out how to get the output created by the "Sky Rig" shelf tool from the Cloud FX shelf to render with Redshift. I have no similar issue with the volume created by the "Cloud Rig" tool, although both seem to me like they create a VDB volume with a channel called "density" (which is what I've tried to render in Redshift with an "RS Volume" shader, which again works just fine with the kind of volume that "Cloud Rig" creates). What am I missing?
  4. Hi, Can someone help, and explain why after translating a cube up in sops, on the geometry node to postion a box on top of another box. then making it a RBD object. then simply add a deactivate object from the shelf tools, why my pivot and object change position when I jump into dops. Perhaps Im missing something silly here, anyone help please? thanks in advance.
  5. Seven Dancing Swirling Blobs

    This is an enhanced version of an earlier animation. This time it was rendered with a dual 1080GTX G1 and 960GTX in Redshift. So instead of taking 3 hours, it took about 1hr30 - I guess there are ways of making it quicker but I'm still in the learning process
  6. [REDSHFT] Materials

    Hi, I am looking for redshift shaders/materials to buy. I am also intrested in importing/converting fbx materaials to Redshift. Anyone have any suggestions? It seems to me that a nice set of materails would make Redshift or houdini a lot more powerful...
  7. I made this video to try out Houdini's Texture Bump mapping, Popnets and Transparency with Redshift... I also wanted to break things!
  8. What are the benefits/applications to creating an .rs proxy of a light? I only ask because I did not realize I was creating an .rs proxy of my object and the light in my scene when I created my archive. I realize now that I just have to check on the "export only selected objects" and it will exclude the light. It would have saved me a few hours of digging if that was checked on by default. Thoughts?
  9. In order to support Stylesheets, RS has to first support Material Override, which has been completed. Next step is Stylesheet support.
  10. Ok, so not a whole lot of Houdini Love over on the Redshift forums. Mostly Maya, 3dmax, C4D (in that order) https://www.redshift3d.com/forums/viewthread/10860/ Hence the reason for my posting here. Anyone care to share any Redshift tips, tricks and tutorials specific to Houdini users? Here is one great tip that Adrian from Redshift was kind enough to share for customizing RS Spot lights https://www.redshift3d.com/forums/viewthread/12283/#79060
  11. Terrain Building in Houdini

    Hello Everyone, This training is will cover the new height field tools introduced in Houdini 16. The training comprises of 5 projects that will cover techniques to create a variety of terrains. Over the course of the projects the videos will cover a majority of the heightfield tools such as noise, pattern, mask by feature, heightfield layer, erode, heightfield wrangle etc. The training is available for Redshift, Arnold, Octane and Mantra. For more information kindly click on the link given below http://www.rohandalvi.net/terrains
  12. Im just getting into redshift and I have been googling around try to figure out if using the instancefile att is possible. I would like to instance files off disk so that I can have control over the frame of the cache that I'm instancing. I set up this simple test scene so feel free to take a look and point out what I have missed. Thanks, Stephen rs_instance.hip
  13. Hi My understanding is that any light names you enter into the Light Mask field will influence that geometry. So a wildcard ‘*’ means ALL lights will influence and by preceding the light name with a ^ symbol, you can subtract that particular light. But it is not working for me. Is there some setting in the RedshiftOBJ parameters that I am missing?
  14. Not so much a specific question but rather I am looking for a working example of a custom Redshift material using Subsurface Scattering I've tried implementing SSS in a custom RS material but so far no luck. Any chance someone knows of one?
  15. Gyrosphere rev 1

    Playing with sound driven animation. Rendered in Redshift.
  16. Hi Discovered if I use a RS Sprite Stencil operation in a custom shader to define the outline of a material I can reduce my poly count in half or more. But will collision recognize this sprite alpha outline as though it was a mesh boundary?
  17. Hello all. This is the latest project I have been working on for my demo reel. Houdini / Redshift. I used growth to effect redshift displacement, some flaking using simple voronoi and spring sop that was activated by the same growth as the displacement. I plan on growing the infection across the beam sections and having them break apart. I was told it needs to be more saturated too. what do you think? All feedback is welcomed.
  18. I am coming up to my final term at Gnomon school of vfx and have the option to do an internship/externship as part of my credits. I feel working in production is where my studies fall short but other that I am rearing to go and become part of a team. I have been working mostly in houdini and rendering in Mantra, Redshift or Vray. Focusing on fx with a side interest in lighting and compositing(nuke). Please take a look at my reel, all of my contact details on in my reel, any feedback is welcome. Thank you.
  19. ok so the whole point of GPU rendering is to speed up your render pipeline. On a current project however if I cannot improve my 5 -10 minutes per frame render times I have no choice but to revert to Mantra (houdini) I'm running a Titan X Pascal card on a Ubuntu linux system with 64gb ram My scene is not too complex and fairly simple to describe. Animated smoke inside a glass sphere surrounded by some animating geometry(think gyroscope) Using 3 point lights inside the smoke, 3 area lights outside the glass sphere and 1 environment light. Outputting to 1080p half float .exr files. Here are my relevant render settings. Which of these should I focus on to reduce my render times(ie would have the least impact on quality and most impact on reducing render time)? Unified Sampling Min Samples 16 Max Samples 128 Adaptive Error Threshold 0.01 Filter Type Gaussian Filter Size 2 Max Subsample Intensity 2 Max Secondary Ray Intensity 2 Global Illumination settings Primary GI Engine Brute Force Secondary GI Engine Irradiance point cloud Num GI Bounces 2 Conserve Reflections Energy checked Brute Force GI Rays 1024 Irradiance Point Cloud settings Frames to Blend 0 Show Calculation checked Screen radius 16 Samples per Pixel 32 Filter Size 2 Retrace Threshold 3 Volumetric Scattering enabled Scattering 0.01 Attenuation 0 Phase 0 Fog Emission Apply Camera Exposure Compensation checked Fog Height .35 For Horizontal Blur 0.08 Environmental Scale 0.537 Camera Scale 0.087 Reflection Scale 0.027 GU Scale 0.595 Environment Alpha Replace checked Sampling Overrides Reflection Samples 512 Refraction Samples 512 Volume Samples 512 (all Samples Scale 1)
  20. Can any Redshift users (or Mantra for that matter) suggest some good starting points for realistic motion blur? You could easilly say "well whatever looks good" but there must be suggested settings assuming you are trying to match the look of a traditional film camera at 24fps. Attached is the Parameters window. Way too many options...wish there was a 'default' button:)
  21. I have a fairly straight forward Voronoi fracture exploding effect in Houdini. Right now I have my RS material applied to a material node after loading my cached fracture .bgeo file but before it enters my autodop network Nothing renders. Can any Houdini Redshift experts possibly have a look at my .hip and tell me what I am doing wrong? voronoi_redshift2.hiplc
  22. Hi I want to use a standard chop expression ie “chop(obj/chop_network/OUT/myValue)” inside a RS vopnet to animate a shader value. Is this possible? What RS node should I be using?
  23. Hey guys, Does anyone knows how can I add motion blur to deforming geometry on Redshift? Here in this example I managed to put motion blur on one sphere, which is animated by the transform tab. The noisy sphere just have a noise animation + trail sop to compute vel. but got no blur. The right object is a flip fluid. No blur as well Scene file is attached in case anyone want to have a look. Thx, Alvaro redshift.deform.geo.blur.hiplc
  24. Making Dessert in Houdini - Training

    Hello Everyone, This training is an update to the Tea and Cookies training. The training covers fairly similar topics such as modeling, shading, lighting and rendering. The primary difference is that instead of Mantra the training focuses on using the third party render engines namely, Redshift, Octane and Arnold. The modeling part of the training covers a variety of techniques ranging from basic poly modeling, VDB, fluid simulations and even POP grains to build the scene. This shading and lighting part primarily focuses is on building all the various shaders required for the scene using a variety of procedural textures and bitmaps. The training will also cover SSS, displacement and building fluid shaders using absorption. We will also build relatively detailed metal and plastic shaders.

  25. Mantra vs Redshift

    Still a Houdini novice, but curious what all the fuss is with 3rd party renderers. Especially hearing a lot about Redshift. Can any experienced Houdniks summarize the key advantages of Redshift over Mantra? RS apparently used to create this impressive still http://jm-b.cgsociety.org/art/sculpture-maya-woman-houdini-nude-redshift-flower-figure-pose-dry-ballisticpublishing-cfe-expose12-figures-adult-3d-1345912
