  1. 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
  2. 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.
  3. 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
  4. I know GPU renderers take advantage of multiple GPU's, but does H16 OpenCL performance also benefit?
  5. 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 :-)
  6. 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?
  7. 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?
  8. 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.
  9. 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
  10. 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
  11. 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
  12. 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.
  13. 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?
  14. 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.
  15. 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.
  16. 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
  17. 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?
  18. GDDR5 or DDR3 GPU?

    Hi folks, I need some suggestion. Should I purchase GDDR5 1GB or DDR3 2GB Readon R7 GPU card? Thanks in advance.
  19. 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
  20. GPU Device choice

    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
  21. 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
  22. 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
  23. 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!
  24. 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?
  25. 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.
