  1. Ok so getting a crash when selecting a new RenderView feature with the latest Redshift plugin of course have submitted a bug report with redshift but the RS logs don't seem to show any errors. In an effort to troubleshoot can anyone look at my Houdini crash log and possibly suggest what the error might be ...possibly driver related? What does 'Caught signal 11' signify? Crash report from jim; Houdini Version 16.5.290 [Linux 2.6.32-573.3.1.el6.x86_64] Uptime 38 seconds Sun Dec 10 14:20:19 2017 Caught signal 11
  2. Linux Mint pros cons

    Currently running Ubuntu Mate 16.04. Quite happy with it but keep coming across other Houdini users using Mint. There is a Mate flavor of Mint as well but my understanding is that in general, Ubuntu is more 'Mac like' and Mint more 'Windows like'. Other than that Mint apparently handles PPA's better than Ubuntu. Any other reasons why Mint might be a better option for Houdini users?
  3. Linux Mint pros cons

    Thanks! Thinking of getting the AMD TR. After reading these articles wondering if I need to upgrade to 17.10 to fully take advantage of the new CPU? https://www.phoronix.com/scan.php?page=news_item&px=AMD-Ryzen-Newer-Kernel https://www.phoronix.com/scan.php?page=article&item=tr1950x-7900x-3os&num=1
  4. Hi Have a dual boot windows 10+Ubuntu MATE setup installed on a single Samsung M.2 SSD. Upgrading my system with new mobo and AMD instead of Intel CPU. Everything else(GPU's, memory, external devices) remains the same. Can I simply install the same M.2 into the new mobo and expect it too boot without issue? My guess is no, but what I am hoping is that I won't have to do a complete fresh install of both Linux+Windows and setup the dual boot again Anyone care to chime in?
  5. Recently discovered multi frame rendering. So is the primary (or only) advantage in multi frame rendering to improve GPU rendering performance? What performance increases can typically be expected, 5%, 10%, more? Does this performance increase scale with number of GPU's? What options are there other than Deadline?
  6. Seriously thinking about selling my 1 yr old Titan XP and 2 1080’s and replacing with 4 FE 1070’s (for GPU rendering). Not 100% happy with the power consumption/rendering performance value. Although its 1.5 year old the 1070 still represents THE sweet spot in terms of price/performance of any GPU out there. And from the bench marks over on redshift3d 2 1070’s are roughly equal to 1 Quadro GP100 but at 1/10th the cost! Two hesitations are 1- OpenCL apparently can only take advantage of 1 GPU, which you would normally assign to whatever your fastest is. 2- The extra 4GB of VRAM on the Titan Am I crazy to even consider this? Anyone know would be the real world (not TDP ratings) total RS rendering power draw of 4 1070’s vs 4 1080’s? (not 1080TI’s)
  7. Interesting product. AMD GPU's were not even on my radar. So what's the consensus with this card, performance benchmarks, etc as compared with say the similarily priced Nvidia 1080ti? There is also the newer Vega 56 and 64. Haven't been able to find many benchmarks. And see that AMD is marketing the duo for 'VR' use. Watching this review my takeaway is that AMD's 56 and 64 only really shine in OpenGl performance over the comparable 1070 and 1080 with the 56 taking a rough 5-7% lead over the 1070 in most benchmarks but consuming 25% more power. In general kind of underwhelming and agree with the comment about these cards having more in common performance wise with older Nvidia Maxwell architecture. In any event cannot seriously consider AMD GPU's since my GPU renderer ONLY supports Nvidia
  8. Is AMD potentially risky? (Threadripper)

    I think this review does a good job summarizing where TR really shines when you get up past the 10-12 thread count.
  9. Is AMD potentially risky? (Threadripper)

    Hi Marty You're making this decision more difficult:) Did you get the 1700x?
  10. Is AMD potentially risky? (Threadripper)

    update, after reading THIS on gamersnexus am reconsidering the TR over the i9 7960 https://www.gamersnexus.net/hwreviews/3066-intel-i9-7980xe-7960x-thermals-power-review and My takeaway is that if you don't plan on doing a lot of OC'ing the TR is the better option. If you want THE fastest, and don't care about power consumption and thermals, go Intel. Surprised by the 100W difference during stock mutlithreaded renders! Another advantage for the AMD route if you pair the TR with the new ASUS Zenith mobo is support for NVME M.2 RAID for insane read write speeds.
  11. Considering this mobo upgrade https://ca.pcpartpicker.com/product/pgDzK8/asus-rog-rampage-vi-apex-eatx-lga2066-motherboard-rog-rampage-vi-apex to marry with a i9 7900x HUGE variety of 16GB simms to choose from Should I save a couple hundred 4 and go with slower DDR4 2666? Or with this CPU will I notice any performance increase with faster RAM?
  12. Is AMD potentially risky? (Threadripper)

    Performance comes at a cost! And not talking just dollars. Anyone else examine the power requirements of these guys? Even at idle the TR is pulling around 100W, and on peak load both are drawing in the 200-250W range. Go ahead and OC the 7980xe to 4.3ghz and you're going to see almost 500W...thats INSANE! If AMD or Intel were to come out with 'power efficient' versions of these that were maybe 90% as powerful, but only required half the power...that is something I would throw my $ at!
  13. Is AMD potentially risky? (Threadripper)

    Ditto, read through the entire thread but still not 100% sure about the findings. Can anyone summarize the pros cons of TR for Houdini sim, rendering as compared with i9 7900? And any Houdini benchmarks yet for the i9 7980x?
  14. Simply trying to apply a Simulate Guides shelf tool to a Guide Deform SOP. .hip attached Why am I getting this error? sphere_oscillate2.hiplc
  15. Add Dynamics shelf tool...where?

    Going to suggest SESI rename this node to 'Hair Spray Amount'
  16. Pulling my hair out (pun intended) trying to get hair dynamics working According to this documentation there should be a 'Hair' tab? and a 'Add Dynamics' shelf tool. I have neither in 16.5! http://www.sidefx.com/docs/houdini/shelf/furdynamics.html Can anyone tell me where it is hiding?
  17. Add Dynamics shelf tool...where?

    Thanks Marty! I derived my settings by trying to convert the settings from an older tutorial.
  18. Add Dynamics shelf tool...where?

    Didn't want to create a new thread Much testing this past week with a simulation using the Apply Fur shelf tool on a simple sphere. As mentioned no detailed information I can find on adjusting simulation dynamics in 16.5! What would be really useful would be hair dynamics settings for a variety of hair types as starting points. It seems that what was the Material TAB has now been separated into Physical and Plasticity TABs. Under Elasticity I have increased Stretch Spring to 3000, reduced both Stretch and Bend Damping to .01, and increased Bend Spring to 5. (see attached) From what I understand, this SHOULD result in my hair or hair guides having much more flex or bend. But I can see zero difference. Can any hair or Wire Solver experts have a look and tell me what I am doing wrong? hair_sphere.hiplc
  19. Add Dynamics shelf tool...where?

    yep, again its a case where the documentation is woefully out of date and misleading! Also discovered this newer 16.5 masterclass.
  20. My understanding is that the recommended way of converting .blend files to FBX is to have Blender already installed and then export to FBX. Also came across this online converter http://www.greentoken.de/onlineconv/ Is there an accepted 'best solution' for this?
  21. 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
  22. OpenCL and multiple GPU's

    Any OpenCL experts able to tell me whether OpenCL is 'multiple-GPU' aware? Just wondering if there are any sim performance advantages in enabling OpenCL on multi-GPU systems...
  23. So taking baby steps in mastering the hair & Fur shelf tools in H16. have watched the masterClass twice. Basic hair guide creation is very intuitive, however when it come to the 'Guide Deform' simulation using the 'Simulate Guides' shelf tool it is easy to get overwhelmed by the options. (attached) The only change I have made to defaults is to reduce Spatial Scale to 0.25, as suggested in the MasterClass. What are some other key settings I should focus on for wedging or flipbooking?
  24. I know you can simple use sin(@Time) to create an oscillating value in an Attribute Wrangle, but how would you use this to create a simple oscillating rotation on any piece of geometry(think clock mechanism or swing)?

    Awesome, thanks!
