Hi there just started using a puppet project in after affects and when I play back my preview my puppet turns upside down and changes colour to yellow and purple for a couple of frames before returning back to normal, it looks like a very quick glitch and happens at the exact same point in time upon replay of the preview. It occured out of no where and im very confused ? Someone please help
Start by flushing your caches. Everything else would require more info like actual system info, details about your hardware acceleration settings and other prevferences, preview settings and ultimately info about your project and screenshots.
