So I was trying to figure out how to create and implement animated textures like this one
I am currently trying to create my own custom zealot,
already got the labeled textures
I dont have a lot of understanding of the map editor but I got a basic understanding of it, just started using it recently
That might be a "Glaze". Try using that as a search term.
For example units on fire sometimes will have a glaze applied to them, or the Shadow units Amon uses in LoTV.
