RainCraft is live on Fab — a full dynamic rain and storm system for Unreal Engine 5.
What it does: reactive wet-surface materials applied automatically to any mesh, live ground puddles with real ripple simulation, fully customizable rain color and intensity from drizzle to full storm, dynamic lightning and thunder with a networked weather state machine, and a drop-in actor that needs no per-material setup.

Happy to answer any questions about how it’s built.
