Godot 4: Cracked glass shader (tutorial)
Hello, everyone! In this video, we’ll create a cracked screen or shattered glass effect through which we can observe the game scene. We’ll combine several programming techniques we’ve used in previous tutorials, and the result will definitely be worth it.

Cracked-glass as a tutorial topic is useful because the effect fails loudly when UVs or normals are wrong — easy to learn from. In a browser export I’ve had to watch overdraw on the shatter pass more than the look itself; once the shards fan out, fill-rate eats mid-range GPUs fast.
Curious whether the tutorial stays on a single draw call with a dissolve mask, or spawns mesh shards. The former has been kinder to web exports in my experience.
