Hi, I have recently created a set of 70+ HDAs called the IPOPs that aim at creating AOVs, Mattes & features for rendering. IPOPs are operator workflows designed to streamline shaders and AOV development in Houdini. With our toolset, artists can easily standardise their networks and access specially developed nodes for various renderers and presets, increasing efficiency and creativity. Get the IPOPs here! Renders in Karma & Mantra. 1. The Standard Library: Set of HDAs that help artists create quick shaders and AOVs and contain useful Utility Nodes such as Fresnel for Karma (CPU & XPU), Mask Falloffs in Shaders etc. The HDA library is constantly updated with new nodes to assist artists in speeding up their workflow and creating a streamlined system thereby increasing efficiency and creativity. 2. The Geometry AOVs: A set of remade common geometry AOVs for artists to quickly generate AOVs, Mattes & Utility Passes for Compositing. 3. The Particles AOVs: A set of remade useful particle AOVs for artists to quickly generate AOVs, Mattes & Utility Passes for Compositing. 4. The Volumes AOVs: A set of remade volume AOVs for artists to enhance their FX using AOVs, Mattes & Utility Passes for Compositing. We have a wide range of Bundles available for various workflows & we support both Houdini Apprentice & Houdini Indie! For any enquiries please email support@chakshuvfx.com I will be posting constant updates and developments here. IPOPs Master bundle: 1. Houdini Apprentice 2.

Hello everyone！ Due to some factors, I only have two choices, AMD R5 4500 and AMD R7-2700, mainly need to be able to run Houdini software smoothly and do some small calculations. Please give me some advice. If it were you, which CPU would you choose? Thank you

Hi all, If my processor is simming and all cores are used but they are not utilized 100% does that mean the processor is waiting for the RAM to be available? Might the ram be too slow to catch up or is that the wrong way of thinking about it? (There's enough free RAM left in this sim). I saw when I lowered separation I can get the CPU usage up to 100%, but at some loads it's not using it fully. Trying to understand if my RAM is too slow, or if it's something normal. Thanks! -Johan

Hey : ) I have (as you can see in my signature) a old 4790k cpu, but a much newer rtx 2060. I just ran a pyro sim with openCL of 90 frames and it finished very quickly at 4 mins 30 seconds. When I use my cpu only (openCL off) it takes over 30 minutes to finish. Before I had my 2060, I was running a 970. OpenCL sims were faster than the cpu on that card too, but not that much faster. Is this just sign my I need to replace my cpu? The only reason I am hesitant is that I would also have to buy a new mother board and ram to go along with it. Thanks-------

Hi guys! I need some advice from hardware magicians. Since our studio is expanding a lot, we are looking to build some new powerful machines to renew our old workstations. Our main software is Houdini, 3dsmax and Modo, and renders are Redshift and Vray. We also want to use them as a farm, when no one is working on them or for night sims/renders. But for this one, it will be only for Houdini+Redshift, so im going to write down the list of hardware that i have in mind, and let's see if you can give me any help to have better specs. We can get up to 5-6k per machine. MOBO: Asus Z10PE-D16 WS CPUs: 2x Intel Xeon E5-2630V4 (i really think that is a bit overkill, i think it will be better and cheaper to get an i9 or one of this new AMD ones) RAM: 2x Crucial DDR4 2666MHz 32GB CL19 DRX4 ECC ( 64gb total, maybe getting 128, since this one will be the main houdini machine) SSD: Samsung 970 EVO Plus 1TB M.2 PCIe NVME SSD: GOODRAM SSD 960GB 2.5" CX300 LIQUID REFRIGERATION: Cooler Master MasterLiquid 120 PSU: Be Quiet! Dark Power PRO 11 1200W 80+ Platinum BOX: In Win 805C ATX GPU: 4x Gigabyte Nvidia GeForce RTX 2070 Gaming OC 8GB Let me know guys! Thanks in advance.

Hey guys, I'm traveling to NY in june, mostly to buy new hardware. Did some research and spoke with some friends and this is what I have so far, wanted to give a last check, my main uses are Houdini sims / motion graphics, redshift/octane, zbrush. MOTHER Gigabyte x399 Aorus Xtreme PROCESSOR Threadripper 2950x RAM G Skill TridentZ 3200mhz CL14 (128 gb) GPU 4 x EVGA GeForce RTX 2080 Ti Questions: Does this mother support 4 gpu? a friend told me to be careful about the space with the power supply and stuff. This threadripper is good? or should I go for another? I want the sims to be quickest as possible For GPU, should I pick the Ti or the normals? there's a 300usd difference between each. P.D: I'm thinking about buying via Amazon, but I'd prefer to go with cash, amazon has AmazonCash but with a 500usd limit, so if anybody knows a nice place to buy this type of hardware at good price in NY will be super helpful. Thanks!

Hi all, I'm new to VFX, in search of a computer to get started with Houdini. My best guess at this point is a mid- to high-range gaming PC. Specs I'm considering: (below) Would this machine work at the intro level? Thanks. Intel® Core™ i9 9900K (8 Core/16 Threads, up to 4.7GHz on all cores, 16MB Cache) NVIDIA® GeForce® RTX 2080 OC with 8GB GDDR6 16 GB Dual-Channel-DDR4 at 2.666 MHz 256 GB M.2-PCIe-NVMe-SSD + 2 TB SATA Windows 10

Hi there, Are there any benchmarking tests out there that are the most indicative of how houdini will perform running larger simulations? I have read that single core high frequency matters though I also here some people pointing to the new Threadrippers which are mellow in terms of frequency but have high core counts. Looking for a high sample size, objective test that will relate to houdini large scale simulations. Not mantra, not small sims. I wanted to add my current setup to add context. I have an i7 6950x OC'd to 4.2 ghz ( watercooled) with 128gb of 2666 ram. This runs fairly well though I see setups sometimes process faster than my setup. This is all part of me trying to understand everything I can about how houdini manages hardware and how you can tune both hardware and software to each other. I do realize that at a certain point this leaves the single workstation and jumps to a very different process of splitting sims up onto a server to process extremely huge sims. I am more so interested in how to min/max the single workstation. Thanks in advance!

Hey Guys i have a workstation with a Xeon E5-2660 Processor (lots of cores but only 2.2 GHz per core) How can i know what nodes are multi-threaded and what are single-threaded in Houdini? i wanna know where things start to get slow because of my cpu. I tried to google it but didn't find sth really useful.

Hi everyone, I am working with our IT department to built up a desktop for heavily FX work(mostly water and pyro simulations). Below are three options that we are considering about it, I am looking for any comments or recommendation on different configuration. Thank you

I am about to buy some new hardware for a workstation that primarily are going to be used for working in Houdini. I am thinking of putting a Ryzen Threadripper 1950x in it, for the high amount of cores, and the relative low price in relation to some other Xeon CPU's. All my rendering is done in Octane, and the CPU will primarily be used for simulations. Are the 1950x, the right choice, for Houdini work?. For what I know, does Houdini support multithreading in almost every aspect, but does the high core count make up for a lower core speed. The alternative is a I9-7900X, where the cores are faster, but the number of cores are lower. Are there any other CPU alternatives in the price range (or a bit more expensive) that would give better performance?

I have a geometry that has a clay material with a texture and it is animated during 45 thousand frames. My computer is 2 x XEON 2,4GHz E560 and i have 8 GTX1080ti and 16 x 8GB Ram Mantra is not using GPU for rendering of course but the % usage in CPU is low while rendering why? what can i do to accelerate rendering? How can i use GPU rendering ? thanks Martin

Hi, I'm looking to build a PC at home and I don't know a huge amount these things so I'm looking for some advice. My budget is around £3k. The main uses will be Houdini, Maya and Nuke. I do a fair amount of heavy fx work and I'm planning to do gpu rendering with redshift. My main questions are to do with which cpu and gpu to go for: CPU - the AMD threadripper looks very interesting, is it worth waiting to see how much that costs and how it compares to intel i7/i9? - are the i9 chips worth it? - or is it better to go for a dual cpu (e.g. dual xeons)? Would that fit in my budget? is it possible to use just one cpu on a dual socket (with the option to add another at a later date)? GPU - I would ultimately like to have 2 or 3 gpus for rendering but, so I guess this influences which motherboard I can get (with enough pci-e lanes) - I think the 1070 seems like a really good option to start with for price/performance

Hi I have 8 GTX 1080ti and i can simulate pyro in fast way with openCL activated however if i render out in mantra linux, it only use low percentage of my 6 dual core i7 processors. why? is it possibile to increase this cpu % or use Gpu for rendering?

This operator allows you to run an OpenCL kernel as part of your SOP network. Depending on the GPU, some operators can be orders of magnitude faster than even VEX. In this case the OpenCL code is 144 times faster than VEX on GTX 970.- 10 replies

Is there any way how I can limit Houdini RAM and CPU usage while writing out simulations with ROP outputdriver? My system crashed few times already while writing out whitewater particles. and I had to start all over again. In Adobe software there's simple setting in preferences - how much RAM to leave for other software to use. In houdini what I found is that I can bump down cache size on DOP, and that is basically it. I'm new to houdini. Also I'm using save to disk in background. so it should use less ram Now simulation is 85% done. so gonna render everything I hope. What I did is I unchecked write cache al all on DOP net and whitewater DOP, don't know if this is the most efficient way to render. Any advice would be appreciated. Thank you My system is not so bad, so I should be able to write out large simulations. Intel® Core™i7 Quad Core Processor i7-4790k (4.0GHz) 8MB Cache 32GB KINGSTON HYPER-X FURY DUAL-DDR3 1600MHz (4 x 8GB) 4GB NVIDIA GEFORCE GTX 970

Hi Guys, I'm about to build a new workstation and I have to luck to know someone who is willing to sell me 2 E5 2696 v3 quite cheap. As you might know, the E5 2696 is the OEM version of the E5 2699. It has the same specs (18 cores/36threads @ 2,3GHz). Thing is, I read a lot on the internet but couldn't find too much about those high core count machines when it comes to Houdini (I'm doing all kinds of sims in Houdini). Some people said high frequency is better than core count most of the time because of single threaded nodes/processes in Houdini. They say, only rendering benefits a lot from more cores. I'd like to know if someone here has experience with everyday use of Xeons in the 2GHz range (scattering many points, mountain sop on heavy geometry, etc). Are those tasks noticable slow? Do many cores help that much with simulations? My other choice is the E5 2687W v3 because it has 3,1GHz (10 cores/20threads @ 3,1GHz). Any help appreciated.

Hello! I haven't seen a resource that benchmarks the calculation speed of graphics cards in Houdini so I thought I'd post this. I hope that people can participate and post their scores using their gaming/workstation graphics cards so other people can get a rough idea of the performance of each graphics card in Houdini before they decide to buy/upgrade anything. This should only take a few minutes - 1. Start Houdini 2. Use the following units under your Hip File Options - Unit Length - 1 Unit Mass - 1 3. Frame Range 1-240 @ 24fps 4. Add a sphere at origin 5. Goto the Pyro FX shelf tool and select Explosion. Select the sphere. 6. Disable Cache Simulation in your DOP and use the following settings - Pyro Container Settings Division size - 0.075 Size - 7.5, 10, 7.5 Center - 0, 4, 0 Resize Container Settings Padding 0.3 Subtract Threshold 0.2 9. Select the Pyrosolver. In the Advanced tab, turn on OpenCL 10. Save the file and restart your computer 11. Use a stopwatch or http://www.online-stopwatch.com/ to keep track of the time 12. Open the file, start the sim and the stopwatch timer 13. Record the time after 240 frames. 14. Run the same sim again but with OpenCL disabled 15. Post the exact times with your PC Specs, Houdini version and OS in the following format (using my results as an example) - Houdini Version - 14.0.201.13 OS - Windows 7 Ultimate x64 GFX - Zotac 770GTX Amp! Edition (2GB) / Driver - 347.09 Time - 1:37.222 CPU - Intel i7 3770K @ stock Time - 2:09.503 Other - ASRock z77 Pro3 Motherboard, 32 GB Corsair Vengeance RAM Thank you! PS - I've attached a hip file with the above settings using Houdini 14 that you can run right away. Thanks for the suggestion, Skybar. OpenCL_TestFile.hipnc

Hey everybody, I'm looking for a new computer and I'm now standing with a dilemma. Should I choose the Xeon 6-core 2.1ghz or a i7 with a higher clockspeed? The thing is, that if I choose to go with the Xeon, I'll choose a workstation motherboard, so that I can expand with 1 more CPU later on. Also what is the most important components for quick renders, and simulations? CPU,GPU or RAM? Thanks a bunch in advance! Cheers, Jonas Jørgensen

I'd like to know if anyone knows why my bullet sim is only using half of the available threads?
-
I am simulating a lot of particles. Why is Houdini not using all threads to the full extent. Is this normal, is this as much multi-threading as I can get out of houdini. I have 4 real threads and its not even using one of them fully (which would be 25%). Just wondering.

I am about to build my first workstation which will be Houdini orientated, I did an extensive research on hardware and I though it may be useful to share it for people who may be in the same place. Also I would like to submit a couple of question which I didn't manage to answer myself. First of all, lets start with my build. Because currently I am not in a place to spend a large amount of money in a super workstation, I have designed two different builds, the first one "budget workstation" is going to use few hardware which I am currently own and it will build on top of those and keeping in mind the second build "ultimate workstation" as an update which may come next year. Why not waiting until have all the money? Because my current pc it's so slow, which is impossible to do anything with houdini. here is the hardware of the two builds: https://docs.google.com/document/d/1ZAVK_vq2cCobbnTsV2ryMokLOaKSBBpK48gX8xX8H74/edit Questions: 1. What is best combination of nvidia? (one for OpenCL and the other for display) 2. Tesla C2075 and GTX 680 can be in the same setup? 3. Is it true that is better to go with the best (Noctua) air cooling than a cheap (Hydro Series™ H60) water cooling? 4. Any suggestion? Please share your experience on the listed hardware or your own setups. cheers

Hello All, I am new to these forums and this is my first post. I am almost as new to Houdini as I am to these forums, so I am just learning Houdini using Apprentice. Houdini works just fine on my current computer, but it is pretty outdated at this point. It was built back in 2007! So I'm looking at upgrading with a completely new build. I've done a good amount of research related to a computer build that would work pretty well with Houdini and based on that I've put together a build. I would like to get some thoughts as to how this build looks and any suggestions and/or recommendations for what to change. The build is linked here: http://pcpartpicker.com/p/lhI9 I do have some questions related to some of the info that I've found in my research: - Is 64 GB of RAM overkill for someone just starting to learn Houdini? I'm thinking of dropping the extra set of 32 GB to save some money. Although $30 off seems like it is a good deal... - I am most likely going to remove the second GTX 680 from the build to save money. How valueable is it to have that second GPU? If I keep (or add later) the second GPU, should the two GPUs be connected via their multi-GPU connector (SLI for nVidia)? Or should the 2 cards be left unconnected? I've never used a multi-GPU setup so I'm not 100% how to configure them. - I've read about different combinations of SSDs and HDDs. What is a recommended setup? In the build you'll see that I've included 1 SSD. Is it worthwhile (value wise) to get a second SSD and have them in Raid 0? I already have 2 1TB 7200 rpm drives in my current computer that I can use. How should I utilize those in this new build? I read a mention of setting up the SSD as a local cache and using regular HDDs for files. Does Houdini use the OS disk as a default local cache, or does that need to be configured? Any suggestions and insight here is very helpful! - This is kind of a random question...I've read that nVidia cards are better for the viewport while AMD cards perform better with OpenCL. What about installing an nVidia card as the main GPU for viewport and installing an AMD card as a second GPU. Then set Houdini to use the AMD card as the OpenCL card? Does this even make sense or is it just a silly idea? What would the advantages and disadvantages be? - I am very much in need of a new mouse and keyboard. You'll see the ones I selected in the build. What input devices do you guys use? Which mouse and keyboard? - Displays. I currently own a BenQ 241W and use a very old Dell 2005FPW as a second monitor. I'd like to upgrade my displays, though I'm not sure what to do yet: get a second 24" or upgrade to a 27"? Which displays and display setups are suggested for Houdini work? Many thanks for your time and suggestions. I look forward to learning much about Houdini from all the awesome info and people in this forum. Hopefully I'll be able to give back one day. Cheers.
