  1. I am new to Redshift. For a very basic scene with three objects, at a resolution of 1280x720, it took 13 minutes to render. I have intel core-i7-8750H, Nvidia GTX1050ti -4GB and 16GB of RAM. This is the output. I have rendered more complex scenes in Keyshot at a resolution of 1350x1350 and it takes 6 minutes max for them on my machine. Please suggest a solution. Here's the houdini file.

  2. Hey magicians, Anybody used TOPs + Redshift + Deadline? is there any magic to do on the process, or should work like a regular houdini task on deadline? Haven't set up deadline in a while, but the client is rendering a TOPs + Redshift scene I made with 10.000 outputs, is there any specific thing to keep in mind? Thanks!
  3. Hi, So this is probably a very simple question, but as someone who's new to Houdini and usually uses Octane, I can't figure out which setting in Redshift controls this white border around my Alpha EXR renders. Can anyone help?
  4. Hi Guys, Looking for a bit of Win10 / Houdini Help with a couple of annoying crashes I seem to be having while doing a multi-frame rendertodisk out of Redshift ROP Houdini doesn't create a log file for these particular crashes in <user>\Appdata\Local\Temp\Houdini_temp so I've attached the only info I can find from Event Manager and Reliability History. EDIT: Another render crash did produce a log which I've attached Running Win10 64 / Ryzen 5900x / 64gb RAM / 3060Ti / Houdini 18.5.696 / Redshift 3.0.57 Any help from someone who can see anything obvious pop out would be great. Obviously it's a VM issue, but a clear idea of how to resolve it would be great. Sorry for the noob question guys and thanks in advance. crash.charl_29960_log.txt
  5. Hello guys I buit a process to build airship from a sphere, all procedural. For the decal I didn't used the labs tools as there was too many missing things indeed. How could I render the decal properly in Arnold and Redshift? Does anyone know please please please? ________________________________________________________________ Vincent Thomas (VFX and Art since 1998) Senior Env and Lighting artist & Houdini generalist & Creative Concepts http://fr.linkedin.com/in/vincentthomas
  6. What I want to achieve on my render: I know that I need very low particle seperation so the turbulent spots are crispy and visible. My test rendering with redshift: https://www.youtube.com/watch?v=CL8iC5EQaoY My Questions: - I don't use any ocean tools for this; just an emitter that hits the wavebreaker collision: Should I better use ocean tools instead plain FLIP and an emitter? - I used a 50m x 40m x 20m scale FLIP tank to somewhat get realistic scale with 0.04 particle sep. It took me about 4 hours to sim and mesh 150 frames. Is this overkill and should I go much lower on the scale? - Entagma made a tutorial about adding the turbulent areas of FLIP as an attribute to the material. I did the same but the white parts are flickering very hard for me when rendered. https://www.youtube.com/watch?v=DhqC13Z_hYc&t=774s Basically how can I reproduce the same look from the reference image with houdini and redshift? Many thanks in advance
  7. Is it possible to bind a string attribute in the redshift material context? This way didn't work.
  8. I have a problem when rendering over 10 million instances, the instance is just a simple beveled cube, the instancing points have varying Cd and pscale attributes, while the pscale can be inherited directly, I have to use a material sop with overrides use local variables turned on and parameter set to basecolor with value @Cd.r, @Cd.g, @Cd.b, in order to use the point color as instance color. My 64G memory gets eaten up after a long preparation time, and houdini stops working. What is the problem?
  9. I am new to redshift. I am using version 2.6.41. If I render the scene with just a sphere and donut, it renders out fine. Despite using a number of samples, I am getting noise on the ground when I have the organic blue volume. Here is the .obj file which is used in the scene. https://www101.zippyshare.com/v/THie8eoD/file.html Here's the hip file. RS_RENDER QUERY.hip What should I do to reduce noise? The render time is quite high too at 8 minutes. I rendered similar geometry (the blue organic geometry is same, only the sphere and torus are different) in Keyshot but the render time is very less. I tried with 100 samples, 200 samples and 500 samples.
  10. I am trying to render out a simple wireframe with depth i.e. the wireframe object fades into the background. Ideally, I want to control the fading threshold in compositing software but I don't have Nuke which is what most tutorials out there are using. Relatively new to render passes, wrote Z depth output into EXR but it is recorded in world units I believe so I find it hard controlling it. I tried using a COP network but can't seem to make it work/don't know how to remap Z depth mask. Any advice on that? Attached file. On a higher level, what is a good option to use for editing multilayer EXR sequences? I typically use Premiere for simple editing but there aren't many EXR tutorials for it? After Effects seems convoluted. Is Nuke my only good option? z-depth-test.hipnc
  11. Houdinified Acrylic Paintings

    Hey peoples! I recently started a personal project with the main purpose to explore setups that I either couldn't do during real production, curiosity or pure fun. As a base and also source of inspiration I'm taking real acrylic artworks of a good friend of mine. The photographs of the real artworks are prepped in Photoshop to be able to extract certain textures which I then use in Houdini to create my setups with. The concrete room was built out of a couple of individual decals and assets from Quixel. The whole thing is then being rendered with Redshift, comped with Natron and finalized in Davinci Resolve. From time to time it's seriously fun to play around with setups without having somebody behind me telling me what to do creatively like in a professional environment. No pressure, just fun Here's the first couple of clips I created in this series. Hopefully it's as fun to watch for you as it was creating it for me! You can also check it out on Instagram, Behance or Vimeo. Feedback, questions or whatever appreciated! Volume 1: Volume 2: Volume 3: Cheers!

  13. Hello everybody, I’m trying to create a transparency gradient on a plane to obtain a sort of “infinite” surface witout any visible limits. But I always have a black area into my render ! (see the screenshots) How can I make that ?? Thanks a lot in advance !
  14. Hi, I have a weird problem with Redshift in Houdini. I looked for solutions searching on Google but couldn't find it. I read Redshift documentation with Houdini plug-in and couldn't find it. If there is anyone who'd know what this problem is and know a solution for it, please help me out. So I created this simple scene with a text and a simple glass texture. I lit it and everything looked fine on Redshift RenderView (See attachment "Capture 1") I even enabled PostFX using Bloom. Color management is set to display "ACES" and Red.709 as "View" However, once I hit "Render To Disk", the MPlay window shows something way different even though it's set as "ACES" and "Red.709" (See attachment "Capture 2") It seems to have a different hue with higher vibrancy. The bloom is affecting the scene a lot more. Once I brought in the rendered exr sequence in After Effects, it looks a lot different than what I saw on MPlay -- which is supposed to be the same file. (See attachment "Capture 3") Not to mention, added "Bloom" effect is nowhere to be seen. Any Redshift experts out there who can help me out? Thank you.
  15. Export spectra map to maya

    Hi, I want to export spectra value from Ocean evaluate - Export to Texture from Houdini and I want to apply same texture to maya and render in maya>arnold or redshift. If there is any help would be highly appreciated . Basically I need to render Ocean Simulation in maya instead of Houdini . Please Help!
  16. I used Redshift to set the Zdepth in AOV and output the exr. When I load the exr output to Nuke, the Zdepth is bright red as shown in the image. The object is not being displayed correctly. Do I need to set a custom depth in this case? I have attached the hip file, so if anyone can provide a sample of how to do this, please let me know. Thanks in advance. Thank you very much. Zdepth.Redshift_ROP1.0001.exr Zdepth.hip
  17. Hello hello, Trivial issue I am sure. I have added a bump map to my geo (fluid sim). I am using the triplanar node and I set it up to Reference. The bump map stays static and doesn't move with the geometry. I am not sure where is the problem. Is it a rest attribute thing? I do have a rest attribute, but perhaps I didnt set it up correctly. I tried Object instead of Reference, but it is exactly the same thing Any clues? Cheers I
  18. Building Explosion

    had to finish building explosion in just few days. this is my first try with pyro, had been learning Houdini for 1 and a half year. mostly working on smokes, particles, and cloth. this is my first preview to them 2 days ago. Explosion.mp4 I felt good about that explosion, want to try higher resolution simulation with more trails coming out of it. New_HD.mp4 here's how it looks now. lol what a dumbass. shouldnt have did that. realized that the trails are moving out too fast, too much, and too big. it all in 1 simulation. so I'll try a new simulation, hopefully this one is better. I'll seperate the simulation, explosion only. and the other one is the trails simulated seperately, gotta slow the trails, and reduce the ammount. wish me luck!
  19. Guys, how come I don't see through the bubbly fluid on top? The bottom orange fluid is in a separate object, rendered normally and the one on top is within a separate object as well, rendered as particles. The bubbly material has transparency 100%, how come I don't see what is behind? Thank you !!
  20. Redshift IOR Glass issue

    I was hoping somebody could help me with a render of a glass bottle filled with fluid. I am using the RS_Material node with the stock glass preset. I'm attempting to get the refraction of the fluid to function as it would in real life where the liquid appears to go right to the edge of the glass. None of the IOR settings get me there, unfortunately. My model is double sided and the normals are correctly pointing outward on the outside and inward on the inside. The fluid is slightly backed off of the interior surface so we're not penetrating. No matter what I do I can't get the refraction to bend "out", but it will bend "in" no problem. I have a few images attached that show what the different settings are. As you can see, an IOR below 1 ( IOR_0.85.jpg ) correctly pulls the liquid inward as you would expect. An IOR of 1.0 causes the glass to disappear altogether. Nothing I do above 1.51 gets the opposite effect, so you're always seeing the glass thickness represented as a big transparent border. Any advice would be appreciated. Thank you.
  21. Hi all, Can anyone recommend a good pipeline or an asset library management tool to use with Houdini + Redshift? Looking at alternatives, Mantra supports relatively simple FBX import and material conversion that (almost) works out of the box with material groups and such. C4D has an asset library to streamline asset management. I tried creating the shelf tool described here but wondering if there's a better method since 2018: I seem to struggle/spend way too long every time I need to import FBX. What's your solution to asset management working with Redshift in Houdini?
  22. Hi everybody ! I’m working on a massive destruction scene (collapsing of 4 buildings with lots of windows) which have finally more than 200k packed fragments… You can see a preview here (the 3td test) : https://www.linkedin.com/posts/lionelalvergnas_bonjour-tous-le-monde-tout-dabord-merci-activity-6789944472420585473-s7mI I’m in trouble with “Object loading” time of Redshift (v3.0.44), with a render time of 7m30 almost 90% of this time is used to load the objects ! How can I speed up this (so long…) time? I’ve already tested the RS proxy, but finally I’ve the same render time with a 2Gb file for just one frame, and I’ve 450 frames… For now, I’ll use Mantra which take “only” 4min per frame, but I would prefer use Redshift because of my RTX3090 ! If you’ve any suggestion, I’ll be happy to read that! Thanks in advance Bye
  23. I'm trying to apply this tiger's UV'd texture to fur/hair. I'm going round in circles and sure i'm being stupid, grooming is new to me. Any pointers appreciated:) Rendering w redshift.
  24. Hi all, First of all, please let me know if somebody else asked this question and got an answer, I looked for an answer here and didn't find any, someone has asked on SideFX forum but nobody answered. anyway, I have a scene with hundreds of thousands of points in it that I wanna render as instances. It works fine when I render with Mantra, the @instancepath attrib works just fine, and it does work with Redshift too but it's very slow and it just freezes when the number of points goes up, even 1000 points would take forever to render with RS. So I was wondering if I'm missing something. Thank you, E
  25. Hello all, I’m a relative noob and while this seems like it would be do-able, I have no idea which nodes I would need to invoke. I would like to map a repeating (but not tiled) texture on an object that already has an underlying material / texture. (So for example, knots on a tree trunk, or pimples on a human face.) The way I imagine this might work is that once I’ve used Scatter SOP to scatter some points on my base object, I would somehow translate those point coordinates to UV coordinates (Not sure how to do this). Those UV point coordinates could then be used along with a texture’s 2D matrix to map its pixel data per point (Don’t know how to do this). I would also imagine I could use a pscale value with some randomization to vary the sizing of this repeated texture (again, not sure at all how to approach this). I'd also imagine I'd want to use some kind of multi-layered shader with alphas in order to preserve the base layer material properties. I should note that I’m using Redshift here, as I imagine this might make a difference as it might have a few more limitations compared to native Houdini texture/materials workflows (though maybe not?). Preemptive thanks to any responders! NpF
