There’s no way to do this directly, but you can control it indirectly with the texture animation module.

Unity - Scripting API: TextureSheetAnimationModule

The trick is to have your atlas sprites be on a grid and set the animation frame curve to a constant value to pick the sprite index.

thanks your advice~,but it is very difficult to match the different size and rotation sprite’s uv,so sad - -
