An After Effects project which has been behaving itself perfectly has suddenly developed a problem on rendering.
It's not a particularly strenuous piece - an mp4 clip provided by the client with some text and Element 3D. Normally the render time is around 20-30mins.
Have spent the past few days attempting to render it both inside AE and via Encoder, and the stated render time has shot up to 72 hours. Even the first few seconds which are literally just a logo animation on a plain white background is sitting there for minutes at a time between frames.
So far have tried all the usual workarounds: purging caches, changing disc cache locations, swapping the project to a new drive, opening the project inside a new project, trying to render on a different machine, to no avail. The only thing that looks unusual is the RAM usage indicator which is saying it's using only 3% of the available 64Gb.
If I Switch off Element, suddenly the RAM usage goes up to over 20% and the project exports at the speed you'd expect - minus the crucial 3D elements of course!
So it leads me to believe that something has gone wrong with Element, although what that might be I don't know. As I say, until now, the project has been working and earlier renders have been fine. No changes have been made to the Element parts since the last successful render.
