I have a number of pointclouds with a lot of particles in them which I cache before rendering on the farm, using the Cache Manager Simulation tab => Caching Files => Cache on Playback and then Lock Playback Cache.
Usually this method works fine, but with my current setup it comes up with some funky playback of some of the cached pointclouds and unfortunately this reflects in errors in the rendering of some of my passes. Sometimes when I load a scene with cached pointclouds, the two front pointclouds will play back sort of as expected, but with a global position offset, and fthese two pointclouds fail to render while the rest (which are identical with another seed and startframe) render fine. I am rendering particles in one pass and shadows in another for compositing in to a live plate, and the weird things is while the various particle passes render fine for all frames, the shadowpass at some point during the shot suddenly miss some of the cached pointclouds - specifically the two closest to the camera. I have no idea if this is a factor, but would like to hear if there are some do's and dont's regarding this workflow so I can get things done without recaching and rerendering a lot to get through this shot.
