Atom Posted February 23, 2017 Share Posted February 23, 2017 (edited) Hi All, I am trying out the Crown Splash preset for H16. I have the Display flag set on my compressed_cache node and I click Save To Disk button to write my 360 frame compressed cache to disk over night. However, this morning I discover that Houdini 16 crashed while writing the cache and stopped at frame 86. So I think ok, at least I have 86 frames, surely the compressed cache in Automatic mode can simply look at the last valid frame and continue simulating from there. This is not the case. When I move to frame #87 the entire sim starts cooking from frame #2 -87 and ignores the fact that that data already exists on the disk. Automatic mode is not smart enough to pick up calculating after a crash. Is there anyway to configure Houdini to use the last compressed_cache frame as the starting point, instead of the start of the simulation? If I change the start of my simulation to the last frame calculated, frame #86, the process seems to start from there but the resulting compressed cache file looks like frame #1, i.e. there is no consideration for the last frame calculated. It is the same as starting over. Edited February 23, 2017 by Atom Quote Link to comment Share on other sites More sharing options...
LukeLetellier Posted February 23, 2017 Share Posted February 23, 2017 (edited) AFAIK, you need to be caching .sim files in order to restart a simulation. The compressed cache files are geometry based, and in order to compress them to the small size that's desired, H removes a lot of the critical data that would be needed to restart a simulation. I don't have it open in front of me, but right on your DOP node you should have the option to passively cache sim files during the simulation process, keeping only the most recent ~5 frames worth of data, so if a crash does occur, it can pick up where it left off.

Guest tar Posted February 23, 2017 Share Posted February 23, 2017 compressed_cache and .sim files are the antithesis to each other Quote Link to comment Share on other sites More sharing options...
