  1. Hey my Render View is working absolutely fine but if I wanna render to Disk I always get a short freeze followed by an Error: Error opening the tile device. I’m using RedShift V. 2.6.41 and Houdini 17.5.173 Hope somebody can help me with that.
  2. 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.
  3. 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
  4. GPU in Houdini

    Could someone please explain how exactly Houdini uses the GPU in a few different scenerios? Apart from drawing the viewport, what else is actually going on under the hood? How and when does Houdini use the GPU over the CPU? or both? Say you have two 4 2080ti's linked in pairs with NVLink. Does Houdini just use one pair, one card, all four, or would it be best to set the environment variable in a way so that one pair is used for GPU, and the other is OpenCL; does it matter? What would be most ideal? Like, if you were doing massive simulations or were to hypothetically use a Quadro RTX card, is that better overall, or more suited to just have one card? I don't really understand how it utilizes multiple cards if at all, and if another card is a bit of a waste. Could a single Titan RTX handle most anything Houdini throws at it, or would someone see a dramatic increase in performance, and how so, if they added another Titan RTX. Is that a huge advantage over the one if you linked those via NVLink? I realize that might be great for GPU render engines like Octane or Redshift, but does it give Houdini an incredible amount of extra performance? Linking two expensive cards together like that, what kind of scenerio would be the limit in a sense? When might Houdini hit a bottleneck if a studio or professional that could afford a configuration like that? Does OpenCL use linked cards like that too? Large amount of VRAM? Thanks for helping me understand
  5. Hey, I took advantage of some of the price drops on GPU's lately with the release of the 20 series cards from Nvidia. I Got an evga 1070ti ftw2 card for 429$( also has a 20$ MIR to drop final cost to 409$). I put this into my machine that has had an evga 1080ti FE card in it since I built it a year and a half ago. I wanted to share the "real world" test results in case anyone else is wondering if it is worth it to pick up another card. The PC is running win10pro, 64gb ddr4 ram, intel i7 6850k 3.6ghz, primary drive is a samsung 960 evo m.2 ssd and a secondary crucial ssd, 1000 watt evga gold G3 psu, Houdini 16.5.268 and redshift 2.5.48 ( i think ) etc... I ran a redshift test on a scene that is a decent size pyro sim, rendered 60 frames at full HD with fairly hq setting. With just the 1080ti in the pc, the render took 38min17seconds. With the addition of the 1070ti, the render took 25min26seconds for the 60 frame sequence. Adding the second card took almost 13 minutes of the sequence render time. I would say it is worth the roughly $400 bucks. With the option of enabling/disabling gpu's in the redshift plugin options, I ran a single frame of the render and here was the result: with just the 1080ti - 26 seconds for the first frame. With just the 1070ti - 34s, with a little boost to the gpu settings on the 1070ti using the evga overclock software - 32 seconds( not enough for me to want to keep it overclocked beyond how it arrived). With both gpu's enabled - 15 seconds. I think I would be willing to buy another 1070ti while the sale/rebate is going on if it will reduce the render time a further 13 minutes. I'm assuming it would, but maybe I'm not adding something up right here. If adding one 1070ti to the machine cut 13 minutes off the render, wouldn't the addition of another 1070ti take another 13 minutes off the render time.? It would be incredible to drop the test sequence render time down from 38 min to 12 min for roughly $800 in hardware upgrades.! I ran all the PC's parts through a component checker online and even If I add a 3rd card, it should still have about a 100watts of buffer on the 1000w psu. Would probably want to add some more/better case fans if increasing the GPU count from one to three.! Anyways, thats what adding an extra card did for me. E
  6. Can someone please give me an indepth explanation as to why the CPU vs GPU sims look different? I have noticed when making a fire sim, GPU gives a bit more streaky and jagged sim (better licks) than a CPU sim which tends to be a bit more billowy with more 'shrooms' or rounder shapes in general. Sadly GPU crashes on any large scale sims yet I really like the look. How can I get CPU sims to look as streaky and jagged as GPU? Any tricks to stop a GPU sim from crashing? Cheers!
  7. Hi, Has anyone seen much information about the latest Nvidia cards that will be coming out end September in relation to GPU rendering.? I have been waiting for the specs on these cards for months, and finally they have been released, but of course all the articles so far that I have seen are still somewhat speculation on performance and "leaks" of specs that may or may not be real and all are geared towards gaming. I must say, some of these leaked tests aren't too impressive, like 5% performance increases on the new GTX2080ti over the old 1080ti, but I would have to assume that's because the software doing the tests isn't taking advantage of the RT and tensor cores. I am disappointed that on a $1200 card, they still only have the same 11GB of ram as the 1080ti has, although it is faster/newer ram, I was hoping for more ram.! Have there been any statements made by redshift or otoy about what speed improvements will come form having a card with "RT and tensor cores"..? Just wondering because I will be needing another 2 gfx cards in the next month, and the 10 series cards are having great price drops recently, some 1070ti's are as low as $399. If these new flashy RT cores are going to be a huge performance gain, then I will probably hold out for at least the 2070's. Any info would be great. Thanks. E
  8. Desktop spec for FX

    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
  9. Hey all, I have started using redshift a few months ago and so far i like it a lot.! I currently have one 1080ti 11gb gpu in the machine I am using it on. Would like to get either another one of those cards since the gpu prices seem to have dropped lately back to something more reasonable, or get 2 1070ti 8gb cards. I have heard that the performance diff is only like a 20% gain for the 1080 over the 1070's, so might be better off with getting 2 of the 1070's. The main question is though, what happens when you hit the render button on your redshift node for a sequence inside houdini if you have more than one gpu.? If I had 3 gpu's, would it automatically render frame one on the 1st gpu, frame 2 on the second, frame 3 on the 3rd and so on..? Would it render the first frame across all 3 cards simultaneously by breaking up the frame to submit to the different cards, is that even possible.? Do the extra gpu's only get used if you use a distributed rendering software like deadline or by launching RS renders from command line.? It seems like you have to launch from command line in order to get the other gpu's to render, but I have never worked with a machine with more than one gpu installed. If I were to submit a 100 frame render from within houdini by clicking the render to disk button on my RS node, would it only use the main gpu even with other gpu's installed.? Any info from artists using multi gpu systems would be great. I didn't find a lot of info about this on the redshift site, but might not have looked deep enough. The end goal would be to have the ability to kick off say 2 sequences to render on 2 of the gpu's while leaving my main gpu free to continue working in houdini, and if its time to end the work day, allow the main gpu to then render another sequence so all 3 cards are running at the same time. I will most likely need to get a bigger PSU for the machine, but that is fine. I am running windows 10 pro on a I7-6850K hex core 3.6ghz cpu with 64gig ram in an asus x99-Deluxe II MB if that helps evaluate the potential of the setup. One last question, sli bridges.? Do you need to do this if trying to setup 2 additional gpu's that will only be used to render RS on.? I do not wish to have the extra gpu's combined to increase power in say a video game. I don't know much about sli and when/why it's needed in multi gpu setups, but was under the impression that is to combine the power of the cards for gaming performance. Thanks for any info E
  10. OpenCL Sim caching with multiple gpus

    Hi, is there anyway to cache my pyro sim in opencl with my 4 gpu (4xgt1080)? i couldn't find any preferences on houdini or topic in search. Thank you.
  11. Removing this post as we got the info needed. Thank you.
  12. I'm looking into graphics cards and i'm finding it hard to nail down exactly what to go for in terms of balancing budget with performance. Obviously getting the 1080ti would be better than the 1070 but there is, of course, the massive difference in price. Just within the 1070 model, limited to EVGA there are still multiple versions to decide between. Is there much wrong with going for the cheapest one? https://ca.pcpartpicker.com/products/video-card/#c=369&m=14&sort=price thanks everyone.
  13. Rendering slow

    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
  14. I know GPU renderers take advantage of multiple GPU's, but does H16 OpenCL performance also benefit?
  15. Which NVIDIA GPU?

    Hi all, I would very much like to try out some GPU rendering and therefore I am looking for a Nvidia GPU. I had found a Asus 1080 Ti Poseidon 2nd hand, but Now want to check in with you guys what you Think is the best solution? any 1080 Ti models that are better than others? If so, which one would you recommend? cheers :-)
  16. OpenCL simulations on ADM GPU

    hi guys, sorry can't speak English well. I planning to buy new hardware for OpenCL simulations on GPU. I study a little about pro-GPUs computing performance and find some information in https://en.wikipedia.org/wiki/FLOPS "Built using commercially available parts. AMD Ryzen 7 1700 CPU combined with AMD Radeon Vega FE cards in CrossFire tops out at over 50 TFLOPS (OMGOD!!!) at just under US$3,000 for the complete system." is it right? Can combine two AMD Radeon Vega FE cards in CrossFire with CPU? Does it help to speed up simulations in Houdini? Which Single-precision or Double-precision floating-point is more important in Houdini? is it depend on 32bit or 64bit process in software? https://pro.radeon.com/en-us/product/radeon-vega-frontier-edition/ OpenCL™ 2.0 Support Enables professionals to tap into the parallel computing power of modern GPUs and multi-core CPUs to accelerate compute-intensive tasks in leading CAD/CAM/CAE and Media & Entertainment applications that support OpenCL. Does Houdini support OpenCL 2ver?
  17. 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?
  18. 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
  19. Laptop Quadro or GTX, pros & cons

    Hello people! I am buying a laptop workstation to use while traveling for a few months later this year and I don't know if I should buy a laptop with a Quadro or a GTX card in it. What are the pros & cons? (price excluded) Does Houdini run better in general on Quadro cards? Also, feel free to drop some laptop recommendations if you have any! I've got my eyes on a Dell Precision 7710. Best regards, //Simon
  20. R9 Fury X

    Hi everyone, I'm considering changing out my FirePro W8100 and was offered a R9 Fury X, which on paper looks better for Single Floating Point calculations, however I am unsure of whether this is useful for Houdini or if I am to look for something that performs better with Double Precission Floating Point? Budget is very limited, so unfortunately no money for Titan X or 1080, etc. Would a Fury X be a viable option over the W8100? Cheers
  21. Hi all, is it possible or a way to enable all my GPUs for OpenCL? i have 3x titan-x and a quadro m4000 total of 4 cards. thanks
  22. Hi, Please let me know if there is a simple setting in preference where we can enable or switch to GPU or OpenCL. I am not sure whether viewport uses GPU, I think it does and I would also like to know if we can directly switch a DOP node to use GPU for its calculations. Can Mantra and Arnold use GPU? Please let me know the specific settings. Thanks again.
  23. Hey, before messing inside my PC, I thought I'd ask here: I have a old GTX580 sitting around, and a GTX980 in my PC. Could I use it to help on GPU rendering? (I'm testing RedShift). Is there some step to follow in order to have it working as dual GPU rendering? Is that 580 too old? Is it worse it?
  24. Hi everyone , When do ı simulate in houdini about pyro,fluid,grain, I disappoited during simulation or at cache time. :/ For this reason , i ask to build pc for houdini dynamics. But I don't know requirements for system . Processor option may be amd or intel. Max budget 3000$ 3500$. In addition , System ? Cpu? Motherboard? Min Ram? Min GPU ? Min Core ? be grateful for your helpful.
  25. Hi, I just upgraded to Octane Render 3 for Houdini, I still need to buy a GTX 1070 for my GPU expansion board and I'm up and running with GPU rendering in Houdini. My question. I really like Octane Render for it's image quality and simplicity. Why aren't their so much character animations done with Octane Render and why seem the Redshift3D guys pushing their software much more then Otoy is doing? Can someone with experience in both render engines tell me the pros and cons of Redshift3D and Octane Render? My humble assessement is that Octane Render is much simpeler to setup and it gives better -> Maxwell Render style -> image quality -> while Redshift3D seems more like a VRAY on GPU type solution with a lot of tweaking required to get decent results. I haven't bought Redshift3D yet, but planning to perhaps in the future. They seem to push their marketing better. It would be nice to have some preset material of Octane in Houdini. -> Although from Rohan Dalvi's video's the shader system doesn't seem to be to difficult. Comments please about the comparison between Redshift3D and Octane. The do and don't about using high res textures in VRAM. Why is Otoy not pushing their software more towards character animation? Thanks in advance.
