[PIXI.js change sprite texture]

Yes, it is very much possible to swap a pixi sprite's texture with gsap.

I was able to swap the texture of a sprite with a canvas this way:

 

const dataUrl = canvas.toDataURL('png');

const base = new PIXI.BaseTexture(dataUrl);

const newTexture = new PIXI.Texture(base);

gsap.set(resource, {
pixi: { texture: newTexture}
});
