Comprehensive blueprint for Godot's GPU particle systems covering everything from basic explosions to advanced shader-driven VFX. You get battle-tested patterns for sub-emitters, custom shaders with USERDATA injection, LOD management, and the critical gotchas that will save you hours of debugging (like why CPUParticles2D is actually better for 2D physics interpolation, or why amount_ratio doesn't optimize anything). The NEVER section alone is worth it, calling out the preprocess crash trap and the emitting-after-finished async bug. If you're doing any kind of visual effects in Godot, from simple smoke trails to million-entity swarms with MultiMesh, this covers the full spectrum with working code samples.
