ASI Animated Textures is a plugin that allows you to replace any game texture with a GIF animation. Just name the GIF the same as the texture is called in the game and that's it. For example fist.gif to replace the fist.
If the GIF doesn't display the way you want, you can edit it by creating a file with the same name as the GIF, but specifying the .cfg extension, like fist.cfg for the fist. Thank you SR_team-y for this plugin.
I made 298 eye blink animations for GTA San Andreas. Animation of the eyes is even under the glasses.
Installation is very simple - upload the files to the root of the game. Works in both single and multiplayer games.
P.S. There will be a lot of good modifications. Happy holiday guys.
