@luminidsgame: I simulated rain drops using Godot's particle system + Ripple VFX on the terrain shader Good fun as an innovation project! Came out really well, loving the vibe. :) Game is Luminids for those interested: https://store.steampowered.com/app/4070510/Luminids/ Solo dev and founder of the studio in Cambridge UK. Happy to answer questions on the shader or process!
