Well, if a render job gets killed, we end up with a partial file. We can then "resume" by starting a new render which takes an inventory of which tiles ended up in the partially-written file, and only rendering the buckets that didn't make it the first time. The problem is that we may be rendering several (and sometimes very, very, way too many) outputs, i.e., lots of AOVs. So some output images may be black in certain tiles where other images are not black in the same tile. And so at the time when the render is killed, those highly compressed empty tiles in one output image may not have been flushed, whereas they were in other output images. The icky situation this leads to is that we have a set of output files that don't seem to agree on which set of tiles have been rendered and which have not. If we could ensure that all of the outputs flushed after we send a bucket (as the "full" tiles already seem to, but the "empty" tiles do not), it would make things a lot easier for us. -- lg On Feb 25, 2015, at 4:18 PM, Piotr Stanczyk <address@hidden> wrote:
