Sprite Mask is three-in-one animation, eye dropper and copy pasting a chosen point on the surface. It's a bit buggy now, the UI to the left can disappear sometimes, but it can be returned if you know the right drill.
Press "F" to select an area to put on the "E" docker, and press "A" to cycle your images. You can have up to 1000000 images in the Shadowforge folder.
