Just wanted to warn people that (for me at least) TemporalAA actually plays havoc with the outlines even with the tonemapping settings changed once a character starts playing animations (looked perfect when characters were standing still).
After lots of modifications to the outlines with no changes I decided to try the AA settings and as soon as I tried either FXAA or None then the outline breakup stopped and I got really good, crisp results.
Whether an end user/viewer actually notices the lines breaking is of course another matter but figured I’d post this to spare people the pain of spending a day hunting non-existent bugs in their materials.
