Is it possible to change material overtime by keyframes in swipe effect? So I watched disney frozen, and at the let it go song, i was wondering, how to change the material texture in a swipe effect (if I do it on AnimAll add on, it just changing dragly, so the texture are really messed up). The point is, i want to change texture from feet to head by swipe effect by horizontal line , not dragging all the texture constantly.
Sorry if my english is bad, im me and im new to blender
Using a simple gradient and color ramp will allow you to control two different materials for the same object:



Then is just a matter of animating the value for the mapping.
