In PixiJS runtime, you can adjust texture filtering and alpha settings by modifying the .atlas file and the texture settings in your code. For smooth edges and anti-aliasing, ensure that the filter entry in your .atlas file is set to Linear, Linear instead of Nearest, Nearest. This can be done by exporting your assets with Linear as the value for Filter min and Filter mag in the Texture Packer Settings. Additionally, you can manually update these values in your code if needed. PixiJS does not have direct equivalents for Unity's sRGB (Color Texture) and Alpha Is Transparency, but you can manage transparency and color space through shader adjustments and texture settings in your PixiJS application.
