To enable mipmaps using the PIXIJS runtime, you can set the texture filters to use mipmaps. This is done on the textures themselves. If you have an atlas with a single page, you can enable mipmaps by setting the filters like this:
const atlas = PIXI.Assets.get("atlasKey");
atlas.pages[0].texture.setFilters(
spine.TextureFilter.MipMapLinearLinear,
spine.TextureFilter.MipMapLinearLinear,
);
This code will generate mipmaps for the texture, which should help in maintaining smoother edges when the Spine container is scaled down. If you have multiple textures, you will need to apply this setting to each texture individually.
