dude! network render in AE : sucks!!! too cumbersome.
Here’s my alternative:
Set up two computers (A & B) with the same settings/fonts/plugins.
Connect via network, then open up the same project on A from B, render the precomps while continuing to work on A.
Final render can be split up b/w two computers. A handles first half while B does the second if need to. If you have more computers, then break up the render even more. Stitch them back up later.
Works so far for me. No hassle with network render.
