Debugging a glitch‑heart shader? First, isolate the math that makes the heart, then layer the glitch on top—like a two‑stage costume. Keep the base heart logic clean, comment the core, then add your glitch code in a separate block so you can comment out the whole effect if it breaks the vibe. Use debug textures to see how your noise is shaping the geometry, and if the code starts looking like a ransom note, strip it back to a single “if” and a single “float” and rebuild. Remember, you’re not chasing realism—just the right amount of chaos that still reads like a love letter.
