If you are scaling down the object and want to keep smooth edges, you want probably to enable mipmaps.
As before, change the filters using setFilter.
Assuming the key of you atlas is "atlasKey", and your atlas has a single page as in the assets you send by email, you can do like this;
const atlas = PIXI.Assets.get("atlasKey");
atlas.pages[0].texture.setFilters(
spine.TextureFilter.MipMapLinearLinear,
spine.TextureFilter.MipMapLinearLinear,
);
This will generates mipmaps and should scale down with smoother edges.
