  1. 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
  2. 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.
  3. 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
  4. 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
  5. 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.
  6. 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?
  7. 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.
  8. 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.
  9. Hi Plan on building a power user Houdini machine to replace my 4 yr old iMac. My understanding is that GPU based renderer's like Octane, Redshift work very well with dual GPU's, so after a bit of research my first choice is to go with dual NVIDIA 1070's. Can anyone familiar with GPU's suggest a reason that the extra $ for 1080's or higher warrants the extra cost? My budget will be around $2500 US for everything and it has to last me for the next 5 years. Here is a starting point I am using (ugly case recommendation but otherwise...) http://techbuyersguru.com/2500-extreme-4k-gaming-pc-build
  10. As much as I am sold on the improved performance of Octane and Redshift (assuming you have a decent gpu) I am highly doubtful they can match the 'high realism' of renders like this one by Maxwell http://www.tonifresnedo.com/maxwell-render/rendl-rossy-lamp/#/gallery_2663/2 Any experienced Redshift or Octane users care to chime in?
  11. Hi folks, I need some suggestion. Should I purchase GDDR5 1GB or DDR3 2GB Readon R7 GPU card? Thanks in advance.
  12. 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
  13. I have to GPUs I like to utilize in Houdini, one for opengl drawing and the other solely for OpenCL computation. Using following variables: HOUDINI_OCL_DEVICETYPE=GPU HOUDINI_OCL_DEVICENUMBER=0 But I am unsure if its really separated or if the drawing card also does the opencl computation. Is there any way to figure out which device is used for what task? tried to monitor with the gpu-z but it is giving some inconsistent results Thanks Sebastian
  14. Hey using HOUDINI_OCL_DEVICENUMBER=1 in Houdini 15.0.244.16 build wont work. There are no problems with the 14 builds. I really would like rule out any hardware/driver issues on my side and need a repro from you guys. Ive already passed this on to the support during the open beta. Thanks
  15. Hello everyone! My name is Panagiotis ("Panos") Zompolas and I'm the CTO of Redshift. For those of you that have never heard of it, Redshift is a GPU-accelerated, physically-correct, production-quality renderer. It offers biased rendering capabilities (such as point-based GI) as well as brute-force-style techniques. It supports out-of-core geometry and textures which allow efficient rendering of scenes the can exceed the GPU memory limits. Also supported are layered/deep EXR, volumetric lighting, hair, deformation/transformation blur, a comprehensive list of AOVs, multiple light types, visibility flags, UDIM/UVTILE support, height/vector displacement, tessellation with crease control, light/shadow object links and many more. For more info, please visit www.redshift3d.com. Redshift is commercially available for Softimage and Maya (3dsMax plugin currently in alpha) and currently in use by many small-to-medium studios as well as a few larger ones. Chances are you’ve already seen at least one Redshift-rendered production in the last few months! Since our v1.0 release a bit more than a year ago, we've been constantly receiving requests to support other 3D apps such as Houdini. Well, we’re happy to say that the time has finally come to expand the Redshift family! So we’d like to use this opportunity to invite any good Houdini plugin developers that might be interested in helping out with this endeavor! There are multiple different ways this could work out in terms of responsibilities, workload and rewards - we'd prefer to discuss these privately. FYI, our in-house developed plugins are written using our own Redshift API. Redshift's comprehensive and rapidly evolving feature set means a great level of integration should be possible, as evident in the currently released plugins. Finally, if you're not a plugin developer but you'd like to see Redshift support for your favorite 3d app and happen to know someone that might be interested, please kindly let them know of this opportunity! Any interested parties should email us at: developers@redshift3d.com Kind regards, -Panos
  16. Hello Guys, I have been working on a FLIP sim for the past couple of days and it keeps on randomly crashing when I cache it using Rop output driver, the error is : "1420: Fatal error: Segmentation fault" This is really annoying, I updated my version of Houdini but it didn't solve the problem. I read on the forum that it is a GPU problem, but it doesn't seem very clear, can someone confirm that? I am wondering if I should invest in a better GPU card (quadro range) but I want to be certain that it will solve the problem. Here is my current configuration : - Intel Core i7 4930K3.4Ghz - 48 Gigs of RAM - Geforce GT640 4Gigs Any help or info on this would be really really appreciated!
  17. http://www.cgchannel.com/2014/09/video-amds-new-gpu-based-raytrace-renderer-for-maya/ And 3ds Max integration: http://fireuser.com/blog/video_demo_of_firerender_interactive_photorealistic_rendering_plugin/ Does SESI consider involving in this? Looks pretty cool according to OpenCL part and I suppose AMD is quite big and stable as the developer (as far as I know only Octane 3 supports OpenCL path). What do you think?
  18. I've recently bought another monitor and I'd like to use it with Houdini. I've read that Houdini doesn't like negative workspace. From what I understand that means that the monitors should be aligned from left to right, with the left one being the main one. Okay, I've done that and created some 2 screen workspaces. However, things are acting very weird. Some things just don't update properly in the viewport. Sometimes they disappear. I've had nulls look like a squigly line instead of the normal cross. Switching from the 2 screen workspace to the default "build" and then back sometimes helps. Sometimes I have to close the program and restart it. Is this a 2 monitor problem or a card problem?... or open gl? I have a AMD Radeon 5770 on a Mac booted into win 7. Thank you for any heads up on this issue as I'm new to debugging this sort of thing.
  19. 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
  20. Hey Guys, I posted a build last week on reddit and got a lot of great responses. So I reworked the parts lists and now would like further advice and feedback from some houdini users! Bottomline Goals: -Stability and Power -Built for Effects simulation and rendering -3D Rendering - Below 5 Grand Thoughts: - I am prob going to move my mother board down to a Gigabyte UP4 - I want to go with a high end GPU but not a Quadro (There Price Performance still seems off to me) but you guys may have experience with better cards too! My biggest concern is GPU be far the only thing holding me back. I have read the system requirments for h13 and looked through the OdForce Wiki but I wanted to get more opinions on the GPU and see what everyone else is using.

  21. There is no better way how to start the New year than smoke your GPU BulletSOP 2.5 preview features implementation of WIP Bullet Library 3.0 with OpenCL(CPU/GPU) support. Please keep in mind that this version supports only fraction of BulletSOP features and It's only for testing and highly unstable! For OpenCL settings, check btSolver node -> Advanced tab! You can activate "old" CPU solver(which has some bugs unlike BulletSOP 2.0.10) and compare result and speed. Testing scene includes 80K boxes(of course you can try to go higher - change settings on OpenCL tab). And If you want to publish some result(s) it's better to restart Houdini(clean memory) before running final simulation. So Let's try it and let us know about your results! Best wishes, Milan Suk BulletSOP binary is free of charge, but You can make a donation and help keep the project running. It's up to you! Download BulletSOP v2.5 preview for Windows(compile on Houdini 13.0.260): bit.do/bulletsop_2_5_preview PS: This is my result on 3 years old GPU!
  22. 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
  23. 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.
