TI TerraInk Buy on Fab
Runtime painting plugin for Unreal Engine

Paint becomes the world.

TerraInk turns gameplay events into persistent splats on world surfaces, then promotes them into replicated procedural scatter through ISM, HISM, PCG, or FastGeo, all at runtime.

Drop it in. Paint. Watch the world react.

Author layers and scatter tiers as data assets, attach a painter component to a pawn, and TerraInk handles persistence, replication, and procedural placement on its own.
