Worlds that behave like the real thing.
miniMassif is a browser studio for worlds the size of a mountain range. Rivers run downhill. Snow sits where snow sits. All of it is yours to shape.
Simulated, then yours.
Nothing here is random noise with a texture on it. The land is worked out the way land is.
The land forms.
Relief rises along a fault line. Rivers find the way down, cut their valleys, pool into lakes and meet the sea at sea level. Climate follows height and latitude.
Life settles.
Forests follow the climate: spruce near the tree line, broadleaf on the valley floor, bare rock on the cliffs. The snow line sits lower on the north faces.
You shape it.
Sculpt the ground like clay. Paint with brushes and slope masks. Draw a lake and the shore finds its level. Move a river and the valley follows.
What you see is what you walk.
One metre on the map is one metre on the ground. The world on your screen is the world you stand in: the same ridge, the same ford, the same spruce. Nothing is redrawn on the way out.
No generative AI. Physical simulation, then your hands.
