The animation clip runs across the desert or a temple and eventually reaches the end of the day where something else happens. When the ritual is occuring, there is one person doing it with a tiki mask or something. The animation style is comparable to Lion King animated.
The ritual is a Aztec sacrifice
Thank you!
Is your movie feature length? Because there's a short film about Aztec sacrifice called Mehua (https://vimeo.com/224637445).
