  1. caching ocean question

    Hey, I was trying to save a compressed cache of my beach simulation. Over time, my ram kept filling up untill houdini crashed (not very far in). My work stations at school have 64 gigs and I have seen vimeo/youtube videos of people getting twice my resolution with half my ram. Also, why would my ram keep filling up if I am caching to disk and not ram? Does it actually cache directly to disk or cache each frame to ram then move it to disk, thus filling up ram? Thanks.
  2. Hey guys, I'm gonna buy a new PC and wanted to ask here for some suggestions. My budget is u$d 3000 to $5000 max My daily apps, Octane, Cinema 4D, Zbrush, After Effects, and currently learning Houdini, wanna do some heavy particle / volume based animations. Saw a friend list on amazon and gave me some ideas: 1) A solid state disk for the OS. Samsung 850 EVO - 2TB - 2.5-Inch SATA III Internal SSD (MZ-75E2T0B/AM) 2) Geforce gtx 980 (whats better, 3 gf 980 6gb or 1 titan z 12gb? 3) Intel Xeon E5-2630 v2 2.60 GHz Processor - Socket FCLGA2011 BX80635E52630V2 4) Motherboard? and RAM? These specs are more for the octane/c4d side, not sure how houdini works, if I need great ram, or great video card, any input will be appreciated Thanks!
  3. 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
  4. Hi guys, I am a beginner with Houdini and I have a strange problem. Yesterday night, I ran a simulation on my Mac (twice) and everything went fine. Today, I tried to run the same simulation on a PC (windows 7 and the same amount of ram) and Houdini slowly ate all the ram and crashed the app. Any ideas? There are some parameters to change/optimize? Thank you for your help. best regards, Lazza79
  5. Right components?

    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
  6. Hi, I've seen a few topics on this subject, but none actually solved the issue in the end. So here's the problem: I'm writing out a flip mesh (vdb) to disk (using the rop output driver), and the first 1-2 frames go just fine (takes +- 3 min per frame). Of course Houdini uses a lot of RAM for this, but the problem is that it doesnt flush it after its finished writing out a frame. The cache stays, and houdini doesnt free up the memory, causing the whole computer to slow down (it then takes like 3 hours to write out 1 frame!). Is there a way to clear the node cache/memory after cooking a frame?flushing the cache from the cache manager isn't really possible (since I'd need to stop the writing after every frame). After i stop the writing, the memory only frees up again after I actually close houdini. p.s. I have an AMD FX8320, with 12GB RAM and a weta digital 3TB green HDD. Using houdini 13, on windows 7.
