I create a composition in Ae. Import the file and dynamic link to desired composition in Pr. Render a native timeline. Save it, then either go back a few minutes later or open the project again and the render preview is gone, requiring another full render to playback smoothly. Are my preview files being discarded or something of that nature?
We don't know yet. The link to the rendered files sometimes goes away, even though the file itself is still on the hard drive. But I've not yet seen a definitive explanation for this error, which means no finite solution.
Thanks again for the tip! This seems to work great for a workaround, as long as I remember to save with that blank sequence active. Haven't had much time to do a thourough test. Obviously something I wish wouldn't be necessary and only think Adobe is working on a fix for this.
