Sets blend modes on PixiJS v8 display objects for compositing effects like glow, shadows, and color overlays. Standard modes (add, multiply, screen) are GPU-accelerated and cheap. Advanced modes (color-burn, overlay, hard-light) need an import and useBackBuffer: true on WebGL, and they use the filter pipeline so they're heavier. The v8 migration broke BLEND_MODES enum imports, so you use strings now. Main gotcha is that blend mode changes break batching, so group objects with the same mode together or you'll blow up draw calls. Covers the full mode table and the backbuffer requirement that trips people up.
