Zoom layer on hover
If you would like to have a layer, which is zoomed in while you have a mouse cursor over it and zoomed out, while you don't, you need to follow this tutorial.
Step 1
The zoomed in state should be actually how you are putting the layer down. So this is the "big version".
Step 2
At the layer window -> Animation -> In, choose "Fade", and change the Opacity to 100%. (Basically you removed the fading animation, as you won't need that.) Then set the Scale X and Y values to be smaller, like 50%. This will be the zoomed out, small version's size.
Step 3
At the layer window -> Animation -> Out, do the exact same. Choose "Fade" and change the Opacity to 100%. Then change the Scale - X and Y to the same as before, in my example 50%.
Step 4
At the layer window -> Animation -> Events -> Plays In When write LayerMouseEnter, and to the Plays Out When you should write LayerMouseLeave. Lastly turn on the Repeatable option, and you are done.
