Hi,
I read through the Adobe recommondations for multiprocessing, I hope I did not miss a crucial point, but here's my problem:
When multiprocessing for RAM preview is activated, it renders the required frames and plays them as expected. Also the area in the timeline appears green as expected. But in the moment I click somewhere, the part of the timeline goes gray again. When I want to see that part again, I have to start the render for that part all over again – it feels like it was not cached at all. When MP is deactivated, it works as expected – but unfornutaley, my comps benefit a lot from MP and the render goes a lot faster so its really slowing me down to deactivate it. Parts that are cached without MP stay in cache when they are in a part that I re-render with MP later. Then just the new MP rendered parts dissappear.
Because this behavior just started at some point my opinion was that its kind of a bug. I purged all memory and cache. I uninstalled AE with this clean uninstall tool from Adobe and reinstalled.
It just happens in some complex comps. So I thought, it might be some option or something that prevents AE from caching mit MP. In one composition, I just have one comp with time remap. When I made a new comp and copy'n'pasted the keyframes, it worked in that manually cloned comp.
Disabling disk cache does not seem to have any influence on the problem.
It's strange and hard to reproduce and I was not really able to boil down the conditions where it happens for sure. Any hint what might be the problem would be very appreciated.
Thanks in advance,
Timur
