Hi Houdini users, I am working on a new system build and wanted your thoughts about using a gaming card(4090) vs a workstation card (RTX a5500)? Main motivator behind this is wattage and thermals. Power consumption is not the concern, but raising the temp in the room by using a gaming card. Plus its very hard to get a 4090 that isn't drastically marked up to where I might as well get a workstation card for the same price. I am eyeing a AMD 7950x(CPU), but am waiting to see the reviews of the new 7000x3D chips coming in the next few weeks. Main reasons for the machine: Motion graphics and future 3D/Houdini work(hopefully). 3D side will be Houdini/redshift Any advice/input is welcome. Thank you for your input

Hello, I have multiple planes in the scene and I want whem to have same material, but different textures. There will be like 20 of them (named l1.png, l2.png, ...), so I would like to assign texture somehow using dynamic texture name. I tried using iteration number in material network, but it doesn't work - it uses only the last number. Added project file with textures. Thank You! example.zip

I want to receive same output as input of my texture image. I tried several options saving different formats, or changing texture color space. But as you can see in attatched 'results.png' file, colors doesn't match. A scene has a camera facing a box. Material has only a texture set to emission channel, diffuse and reflection weights are set to 0. The closest result would be AdobeRGB PNG16bit, but still greens and reds doesnt look the same. Why is that and how to achieve same output image as input? rgb_test.hiplc

houdini Ocean displacement with Redshift in Houdini
e1mirmammedov posted a topic in Lighting & Rendering
Hi! I used displacement mask for redshift in Houdini.But there was such a problem.I don't want displacement where I mask and blend into the ocean smoothly. You can see the problem on the edges of the mesh in the first photo.How can i fix this? I shared the displacement mask and material setups below.I will be glad if you help.Thanks in advance.

Redshift Essential Materials is set of Houdini presets which have been built as an introduction to the most useful Redshift parameters, features and nodes. Redshift Essential Materials for Houdini A collection of 70 pre-build setups for Houdini which demonstrate Redshift’s most important and useful nodes. Each material includes remarks in the network to explain the nodes. This library is a great way to learn how particular nodes work in combination with objects in your scene, as many of these examples require the use of the Redshift options available on your geo nodes. Product Summary 70 Redshift materials with notes Houdini project files for each setup Dispersion, Absorption and SSS effects Wear & tear, dust & surface techniques UV projection, normals, camera, object & world space Using attributes in materials Render points, splines, particles & hair Create wireframes and sprites Render Volumes & OpenVDB files Example scenes for Utility AOVs Recommended requirements Houdini 19.5 Redshift 3.5.06 and above

Title is a bit misleading.. I realise Pyro volume simulations don't really have a birth and death point, but what I'm hoping to achieve is to be able to colour or alter the transparency of my fire closer to the base or emission point of the fire. Currently my fire is looking really nice, apart from the base of the fire where it first emits from. I'd like to make this area more transparent. I'm using the Redshift volume shader, but unfortunately cannot post a .hip file due to work non disclosure stuff. I can create a simplified version of the scene if need be. -

hey, we're working on a project where I cache a proxy of geo, do my pops sims, and call the proxy from disk at rendering time using the "instance file" attribute per point. works great. However, the whole scene needs to be Archived to a redshift "Scene Proxy" and sent over to another artist who has different named drives. it works great when rendering from my end, but when the other artist using Maya imports the "Scene proxy" which calls the "Geo proxy" from Drive and it fails to load because it isn't the same path. in the Docs, it mentions using the REDSHIFT_PATHOVERRIDE_FILE can be used. I was hoping it would be like in obj level the override user data tick box to override that proxy path, like the "Material Override list". But it isn't the case. the Doc states So, for example, if the environment variable is set to REDSHIFT_PATHOVERRIDE_FILE = C:\mypathoverrides.txt ... the file mypathoverrides.txt could contain the following, which helps to map from a local folder to some shared network location "C:\MyTextures" "\MYSERVER01\Textures" "C:\MyVDBs" "\MYSERVER01\VDBs" How do I Implement it in Houdini and in Maya? thanks -
Hi guys, I would like to use the color channel of the Redshift's material volume node. 1) I created a vector point attribute called "absorption". 2) I added this attribute's name to the "Volume Rasterize Attribute", attributes list, to create a volume called "absorption" 3) In the "volume source" node of my pyro DOP, I added "absorption" as the source and target field (as vector type). 4) I add a "VDB vector merge" node before my pyro material node. 5) In the RS Volume material, I add "absorption name into the color channel. But it doesn't work..! How can I fix it? Thanks for helping. Absorption_01.hip

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.

When rendering in Redshift, in the rop under the AOV section you can select cryptomatte as a custom output. There are four ID Type options you can choose from: Node Name Material Name Object ID Custom Name ID Does anybody know how to make option #4 work? It seems like there's a very powerful component to the cryptomatte functionality that nobody is using, unless i'm mistaken. There's no better program than Houdini at making carefully placed and named attributes, but what do you do? I tried making a primitive attribute called "Name" but that did nothing. Is this even implemented in Houdini?

Hey there, after years I finally decide to study Houdini more seriously. I'm starting again with the Particles course from Applied Houdini, I just finish my first run with the 2nd vol. and I'm really interested in GPU rendering because of rendering time. It's not that I don't like Mantra (actually sounds super interesting to have a native renderer so robust), but for example the last scene I worked, with like 50M particles, took me more than 10 hours to render like 4 seconds at 1280x720. So I would like to take some advices from you: since I'm just a beginner, is it interesting to already try to work with a GPU renderer, like Redshift, so my rendering time will be faster and I'll be able to explore and study more things quickly as well? Or should be better to keep with Mantra and get more knowledge about it? Thank you!

Hey guys, I created a simulation in Houdini and wanted to export it to cinema 4D with alembic. It worked completely fine but the Material (Redshift) doesn't stick with the Simulation. As you see in the pictures the half of the simulation gets white and this keeps going until its completely white. I just used the default glass Material and didn't change the geometry. Does anyone know how to fix that?

Hi everyone, I'm newbie to Houdini and Redshift... I need your help! I failed to render Cryptomatte with correct object ID, and want to re-render only Cryptomatte without rendering main images to save time. Is it possible or is there any way to skip rendering main images? I just don't want to waste time to render the same images again..... I appreciate your help! JK -
Hey everyone! I am facing a problem while rendering and I don’t understand how to fix it. I have 50 layers of primitives with same texture, but on rendrs shown only 6 layers?, other disapers. All 50 layers visible only on borders of my primitives. I will be grateful for your help, thanks in advance!

Hi all, I'm very new into Houdini, but I'm loving it. There are certain things that they must be quite simple to do but I'm not finding the way. This is importing a png sequence to use into the diffuse channel of a Redshift material. If anybody can help it'd be amazing. Cheers, Sebastian

Hi, I am in the process of setting up a sky full of clouds - using VDBs. I have set up an early proof-of-concept test, can render it, and it all works out of the box. What I'm struggling with is how to maximally optimize it. I have seen an Arnold setup in Houdini, similar to mine, with 3000 cloud objects - using ass files and rendering an HD1080 frame in around 5 minutes, and using less than 100Mb of memory. Pretty efficient! My Redshift test, has a similar number of VDBs exported out as a single rs proxy which is then instanced across scattered points on a grid. I expected this to speed up the rendering process significantly. Sadly, it actually takes over 4 hours at the same resolution and uses more than 5Gb of memory! What I want to do is leverage the power of proxies and instancing to render this setup and at least match what can be done in Arnold - Redshift is after all a definitively faster render engine. Does anyone know an efficient and effective workflow for this type of solution please? I feel like I've missed something here; as usually Redshift is very fast. Many Thanks, Scott

With the help of both the Redshift community and resources here, I finally figured out the proper workflow for dealing with Redshift proxies in Houdini. Quick summary: Out of the box, Mantra does a fantastic job automagically dealing with instanced packed primitives, carrying all the wonderful Houdini efficiencies right into the render. If you use the same workflow with Redshift, though, RS unpacks all of the primitives, consumes all your VRAM, blows out of core, devours your CPU RAM, and causes a star in nearby galaxy to supernova, annihilating several inhabited planets in the process. Okay, maybe not that last one, but you can't prove me wrong so it stays. The trick is to use RS proxies instead of Houdini instances that are in turn driven by the Houdini instances. A lot of this was based on Michael Buckley's post. I wanted to share an annotated file with some additional tweaks to make it easier for others to get up to speed quickly with RS proxies. Trust me; it's absolutely worth it. The speed compared to Mantra is just crazy. A few notes: Keep the workflow procedural by flagging Compute Number of Points in the Points Generate SOP instead of hard-coding a number Use paths that reference the Houdini $HIP and/or $JOB variables. For some reason the RS proxy calls fail if absolute paths are used Do not use the SOP Instance node in Houdini; instead use the instancefile attribute in a wrangle. This was confusing as it doesn’t match the typical Houdini workflow for instancing. There are a lot of posts on RS proxies that mention you always need to set the proxy geo at the world origin before caching them. That was not the case here, but I left the bypassed transform nodes in the network in case your mileage varies The newest version of Redshift for Houdini has a Instance SOP Level Packed Primitives flag on the OBJ node under the Instancing tab. This is designed to basically automatically do the same thing that Mantra does. It works for some scenarios but not all; it didn't work for this simple wall fracturing example. You might want to take that option for a spin before trying this workflow. If anyone just needs the Attribute Wrangle VEX code to copy, here it is: v@pivot = primintrinsic(1, “pivot”, @ptnum); 3@transform = primintrinsic(1, “transform”, @ptnum); s@name = point(1, “name_orig”, @ptnum); v@pos = point(1, “P”, @ptnum); v@v = point(1, “v”, @ptnum); Hope someone finds this useful. -- mC Proxy_Example_Final.hiplc

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.
