Hi, 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?
I have a long-ish PBR render (4-5hr frame) that ran to 66% with checkpoints enabled before timing out on the farm. I resubmitted the frame with checkpoints enabled and got the message: >Resuming from checkpoint file: read 4040 tiles from /path/to/bla_sh004_lighting_v010_bty.1062.exr.mantra_checkpoint (I presumed this meant a successful resume) I then watched as my new render started from exactly the same tile as the first render... it didn't seem to actually skip any part of the render. Is this expected behaviour? Am I misunderstanding checkpoints? I figured this should start back up SOMEWHERE near the percentage of completion I got up to previously, but it appears that's not the case... edit: interesting observation is that looking at the images in Nuke, the same tiles (up to 66%) in the EXR are there - just a hunch that the new render is just rendering straight over the old tiles instead of recognising that they've, in fact, been completed. Is this possible?
