They are actually different animations. Eg. Look at saladin: when you meet him, he strokes his beard. In the civilpedia, he doesn't. I think there are different animations for different moods, and different ones for the civilopedia.If the pixel thing was the case, then why doesn't it effect the civilopedia? Seems like that is the exact same animation for the most part.
That pretty much confirms it. Wait for Firaxis to provide non-shader leaderheads
Does this usually happen? Can anyone confirm that Firaxis provides this down the road?
