Movie/Flipbook Masks Playing Out of Sync
I keep coming across a quirky issue when making movie/flipbook materials with an alpha channel running in the opacity mask. What's happening is that the animation is not syncing up with the animation of the mask so my animation is being masked out at the wrong times. Sometimes a rebuild of a restart of UDK fixes the problem but this time the material just doesn't want to sync itself so I'm resorting to asking for help.
I've been doing some tests with different resolution masks/textures.
It seems that anything greater than 512x512 will not play synced up for movie textures with a movie mask. Flipbook textures/masks sync fine even at 4096x4096, after the restart udk trick, but movies are limited.
Anyone have any idea what is going on here?
I solved this problem with Kismet. In the properties of the movie textures make them not auto play and then in Kismet make them play on level load or whatever trigger you want. They will sync then.
