I did a ram preview of my project, about 12 seconds long. Everything looks good until I want to zoom in or out on the comp, then the green line disappears and I have to render it over again. I don't remember AE doing this before. If I zoom to say 25% and render part of the comp, then zoom to 50%, that part with the green line is gone. I can render a different segment of the comp while in 50% and switch back to 25%, and the green line from when I rendered at 25% is back. I've turned off adaptive resolution in the fast preview options, and I turned off the disk cache. Is this a bug or just the way AE works now? I'm using CS6 version 11.0.2 on Win7.
Are you changing the resolution of the comp window?
Actually, I think I am. I didn't notice it before, but when I zoom in, if I have the resolution set to Auto, it changes between quarter, half and full depending on the zoom level. I've never noticed that before, or maybe they only recently made it so it didn't say Auto all the time, but now says what effective resolution it's set to. So is that the answer to my problem? Leave it on full resolution (or whatever I need at the time)?
AE only caches at the current working resolution.
