Walkable demo

Cretaceous floodplain

Walk a 60 by 47 metre floodplain built from the Dinosaurs and Prehistoric Life pack: twenty-one animals at real scale, from velociraptors and a nest with a hatchling to a roaring tyrannosaurus, a brachiosaurus and a diplodocus.

About

One scene from 24 of the pack's 45 models, on plain ground in the outdoor preset with daylight, among ten tree ferns.

You start at the south edge beside a pack of three feathered velociraptors, a footprint slab and a skull fossil. Ahead are the triceratops pair and a styracosaurus, the roaring tyrannosaurus, and further off the stegosaurus, an ankylosaurus, a pachycephalosaurus, a kentrosaurus, an allosaurus and a dilophosaurus. A nest with eggs and a hatchling sits under a standing quetzalcoatlus, two gallimimus run along the west edge, the spinosaurus and a dimetrodon hold the corners, and the brachiosaurus and diplodocus stand at the north end with a parasaurolophus between them and a pteranodon soaring above.

Nothing moves: this pack ships without animation clips, so every animal holds its pose. The ice age steppe and marine reptiles in the pack are not placed here.

Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.
