Just got the script from your Gumroad, and I gotta say it works amazing!
They are very simple and small, but will have lots of different files. I’m using it for environmental purposes. I tested it without re-using the texture to see if it can candle multiple GIFs without lagging and it works good. (I’m attaching a video) (Butterflies are the animated sources)
I think I’ll stick with this solution instead of VideoTexture 
Thank you!
