.sim caching AND .bgeo.sc caching randomly stop???
5D-VFXTime posted a topic in EffectsDear Houdiniers, I am doing a heavy FX shot, mostly FLIP colliding with geometry and whitewater from that FLIP. I need to cache multiple .sim and .bgeo.sc sequences for various different SOP and DOP nets. It WAS..... all working fine, but now caching anything it seems, whether "save to disk" or "save to disk in background", doesn't work properly. In save to disk it seems to hang and when in background randomly decides to finish early and jump to 100%. There seems to be no pattern to the amount of $SF it gets to, at least none I can discern. I have tried down rezing it and allowing caching to disk to no sucess. I hope someone can help. This is a shot that may land me my first job in the industry, fingers crossed! Cheers 5D PS: haven't included .hip because it has so much cache all over the place. Should I upload it anyway??
Resuming a crashed flip sim via "initial state"Hi there, I have to resume a crashed flip simulation. I cached out the .sim files directly. My simulation crashed at $SF 60. My question is the following: When I load $SF 50 from my cache as the initial state in the dopnet and adjust the output range, do I need to start the new output at $SF 50 or $SF 51. I would assume that $SF 51 would be correct since I load $SF 50 as the initial state and continue the solve from there. What makes me a bit nervous is that when I compare the filesizes from the crashed solve and the continued solve the sizes for corresponding frames are varying - shouldn't I get the exact same solve when continuing the simulation via loading an initial state? Am I missing something else? Any hint much appreciated!
Hi Guys I have a fairly high res flip sim (by student standards, about 3 gig per frame) and I needed to cache it out as a .sim to utilise checkpoints I need to read this simulation in using playback simulation on the dopnet and a dop IO node with the flip presets in order to pull in the velocity fields for a whitewater sim, however when I do this the computer gets stuck on the first frame I load in. My only current solution is to go through every frame, unticking and reticking the playback simulation button which would take me 2 minutes of load time per frame for 432 frames. An alternative I've considered is the Houdini python module however I am not familiar with this and don't know if the required functions exist. Please could someone with more knowledge on this tell me if this is possible in the python module or whether there is an alternate solution such as a way to pull velocity fields from a .sim cache Thanks George
How to reload .sim files
ronit1996 posted a topic in General Houdini QuestionsHi, I am doing a smoke sim. The sim is too large and so I can't simulate the entire sim in one go. I had checked the checkpoint option and gave a valid path to save the checkpoints files then simed half of the simulation and had closed houdini. I want to sim the rest of the simulation but where do I put the .sim files that are generated by the checkpoint so that the sim runs from a certain frame and not from frame 1 all over again?
