Living Fields — Interactive Grass & Crops

Living Fields grows interactive fields in Unity 6 URP - wheat, barley, reeds, tall and short grass and wildflower meadows - on a Terrain or a mesh. Every plant bends under characters, vehicles or any collider and springs back with a light swing, and a field of millions of plants stays fast with per-plant LOD and batched drawing.

DRAW A FIELD IN MINUTES

Create a field from the Tools menu, draw zones point by point right on the ground, pick a crop for each zone and paint density with Restore, Erase and Smooth brushes. One brush stroke cuts a road or a clearing through several zones. Holes, per-zone height and density, zone priority and full Undo are built in, and a yellow hint banner always shows the keys of the active tool.

SIX ORIGINAL PLANT PRESETS

Wheat, Barley, Short Grass, Tall Grass, Wildflower Meadow and Reeds - original procedural plants with near, middle and far detail, a distant canopy that keeps the field dense to the horizon, ripeness, translucency, sheen and wind with gusts.

INTERACTION THAT FEELS PHYSICAL

Any SphereCollider, CapsuleCollider, BoxCollider or CharacterController tramples the field. Pressed plants hold for a moment and stand up like a damped spring - a smooth start, a light swing past upright and a slow settle - each stalk with its own timing. Trails can be held for the whole session or cleared at once.

FAST ON LARGE MAPS

Per-plant level of detail with exact CPU selection, GPU-batched drawing, simplified shadows and a far canopy keep a 2 km field interactive. Low, Medium and High quality profiles are included; save your own profiles with Save As.

LIGHT THAT READS LIKE A REAL FIELD

Canopy depth shading, interior fill and warmth, ground shade and sheen on the tops make the field look dense and deep in daylight, at golden hour and at night. The included time-of-day sample drives the sun, moon, stars, sky, fog and colour grade from one slider.

WHAT YOU GET
