Dress any terrain with plants, rocks and litter in a few clicks, and keep your viewport fast.

Grounded scatters grass, flowers, trees, rocks, leaves and props over any surface. Pick one of twelve ready-made biomes, let Smart Terrain read your land, or paint where things grow.

Simple rules decide where each layer appears, and the layers relate to each other. Flowers fill the gaps in the grass, ferns clump against fallen logs, leaves pile up at walls and pebbles settle in hollows. One slider turns the whole scene to autumn, under snow or wet with rain.

Everything runs on Geometry Nodes and materials inside your file, so scenes render without the add-on.

This is the Blender viewport in Material Preview. Pick a biome, click Add Biome, and every layer, rule and wind setting comes with it. The wait is cut from these clips; the time on screen is what it took on a Ryzen 7 3700X and an RTX 4060.

Grounded bakes maps from your terrain and adds library layers that follow it. Reeds and flowers along the water lines, forest with ferns on the slopes, grass on the flats, boulders on sharp crests and steep ground. The zones fade into each other, and the result is plain layers you can tune or delete.

Two biomes fade into each other instead of stopping at a line. The edge follows a direction, a curve or your paint, with a soft width and some noise so it wanders.

Season, Snow and Wetness are scene values that every material reads by itself. Only green parts of a texture turn, so flowers, bark and rocks stay as they are. Snow lies on what faces up, whichever way an instance is turned. Library assets have it built in, and one click adds it to your own.

Paint a layer onto the ground, erase it anywhere, or place single instances under the cursor. Strokes live in hidden helper objects, so your model never changes and any mesh resolution works.

Drag a setting and the layer follows in the viewport. Slope, height, facing direction, patches, masks and clear paths stack up, and every rule has a soft edge.

Real ground isn't random. Leaves blow into corners and against walls, gravel rolls into ditches, needles fall under trees. Grounded's gathering rules make a layer denser in those places, or let it appear only there.

In the Autumn Street biome maple and oak leaves pile up in the gutter and along the walls, litter collects at the curb and weeds grow only in the cracks. Pick your own walls with one click.

Plants come in groups. One layer can grow toward another or keep away from it, and Bare Ground opens clearings at the same spots on every layer, so grass, flowers and clover leave the same ground free.

Blend Ground turns the soil into damp humus under the leaves, with bare earth between the drifts.

Lay straight rows for fields and orchards, or put them along curves for fences and vineyards. Clumps turn every point into a parent with children around it, for tussocks, reeds and mushroom rings. Draw a curve and every layer clears the lane, or follows it.

Paths

Physics Drop lets instances fall and settle. Rocks roll into hollows and rest against each other, and no simulation stays in your file. Any single instance can be moved, turned, scaled or removed by hand. It remembers its place when you change the seed, the density or a rule, and the layer changes around it.

Hand edits

Dryness turns plants yellow in patches and leaves flowers and bark alone. Every plant comes out a little lighter or darker than its neighbour, and the undersides of leaves come out paler.

Instances rise from the ground over the frames you choose, one by one or in a wave that crosses the surface from any object. Grass doesn't jump around a tree that is still small, and layers that don't grow stay out of the way on a frame change.

Gusts sweep across the ground in the wind direction. Grass, flowers and shrubs bend, and on library trees only the leaves move while the trunks stand still. It is on by default in every biome and keeps working without the add-on.

Every biome is a set of ordinary layers. Change the density, swap assets or paint over them. These are Cycles renders of the biomes. Terrains and skies in these images are not part of the add-on.
