This is a little thing, but a big frustration - I cannot for the life of me figure out how to get AE2015 to render or play previews from the current time marker. I've experienced this on multiple systems, and it doesn't matter what combination of preview tab settings I try. Can't find anything about it in the preferences, either. Preview ALWAYS renders and plays back from the beginning of a comp.
If anyone has figured out how to render and play back from the current time indicator, please tell me how you did it!
Just another thing Adobe's "fixed" that wasn't broken to begin with, and now our user experience is effected detrimentally.
It works for me just fine. Are you pressing spacebar or 0 to start your preview? Can we see a screenshot of your preview panel settings?
