Primeval Frontier: Walk the Dinosaur Valley

Walk a dinosaur valley: a nest colony, fern forest, lagoon with spinosaurs, sauropod flats, predator ridge and fossil ravine from 50 pack designs.

About

Walk a Cretaceous valley on a 60 by 54 metre plot: an arch gate, a nesting colony on a forest mound, a fern forest with browsing iguanodons, a lagoon crossing with spinosaurus and baryonyx working the shores, sauropod flats with brachiosaurus and diplodocus, a predator ridge with four theropods, and a fossil ravine under a columnar basalt wall. Built from 50 of the pack’s 54 designs in over 200 placements, ground sunk so slabs read as terrain and tracks pressed along the trail. Nothing in the pack ships animation clips, so the valley reads as a still hour: every placement uses the default proximity trigger and there is nothing to stage always or off. What is not placed and why: the four composed scenes (River Hunters, Herbivore Migration, Feathered Nesting Colony, Fossil Ravine) are complete 16 to 17 metre dioramas; placing them would show the same designs twice and swallow the valley, so the demo builds its own river, herd, colony and ravine from the members instead.

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.

Points of interest

Gate of the Arch
Step under the weathered arch onto the valley trail. Ahead the lagoon glints, and beyond it the sauropod flats with the volcanic cone behind.

Nesting Ground
A six-egg clutch ringed by fiddleheads while an oviraptor circles the mound. Hatching eggs and broken shells mark the fresh end of the colony.

Fern Forest
Arching tree ferns, crooked trunks, cycads and ginkgos crowd the west mound. Iguanodons browse the edge where the forest meets the trail.
Tree Fern: Arching Canopy (Primeval Frontier: Dinosaur Worlds)
Lagoon Hunters
Wade the shallow lagoon crossing. A spinosaurus works the west shore and a baryonyx the east while dilophosaurs patrol the shallows.
Spinosaurus (Primeval Frontier: Dinosaur Worlds)
Horned Herd
Styracosaurus and parasaurolophus hold the middle ground between the water and the flats, with the first long necks rising behind them.

Sauropod Flats
A brachiosaurus and a full length diplodocus graze the open flats, flanked by stegosaurs, an ankylosaur and the horned herd.
Brachiosaurus (Primeval Frontier: Dinosaur Worlds)
Predator Ridge
Tyrannosaurus, allosaurus, carnotaurus and ceratosaurus watch the herds from the basalt ridge to the east. Keep to the trail here.

Fossil Ravine
The trail ends at a dig floor under columnar basalt: an exposed ribcage, a theropod skull and track patches pressed into the scree.

Common questions

How do I use this scene with my AI development tools?

Press "Copy for AI agent" above and paste the prompt into Claude Code, Cursor, Codex, GitHub Copilot, ChatGPT or any other coding assistant. The prompt carries the direct CDN URL, the real-world size, the licence and the loading notes, so the assistant can fetch the scene and place it in your project without you writing the loader yourself. For a permanent connection, add the 3DAssets.dev MCP server to your tool with one command (for Claude Code: claude mcp add --transport http 3dassets https://3dassets.dev/mcp) and the assistant can then search the whole catalogue, fetch files and read the usage snippets on its own.

How do I get started?

Walk the scene here with the keys or touch to see how the pack fits together. To build it yourself, download the pack with the button, then copy the "Copy for AI agent" prompt: it links the layout JSON, which lists every placement with its position, rotation and CDN URL, so an assistant connected to the MCP server can rebuild the scene in your engine and change it to order.

MCP server setup

Which game engines and tools can I use this scene with?

Anything that reads glTF, which today means all of the major ones: three.js and React Three Fiber on the web, Godot 4, Unity, Unreal Engine 5, Blender and the model-viewer web component. Every model in the scene is a self-contained binary glTF (.glb) with textures embedded, so each is one file to import and no plugin, converter or decoder to install first.

How do I import this scene into Unity, Godot, Unreal or Blender?

Unity: install the glTFast package (com.unity.cloud.gltfast) from the Package Manager, drop the .glb into Assets and drag the prefab in, or load it at runtime from the CDN URL. Godot 4: copy the file into the project folder and the editor imports it as a scene you can instantiate. Unreal Engine 5: File > Import with the built-in glTF importer, which converts the axes for you. Blender: File > Import > glTF 2.0. Units are metres with +Y up in the file, and every importer above handles the conversion to its own axes automatically.

Can I use this scene in a commercial game, and do I need to credit anyone?

Yes to commercial use and no to credit. Every scene on 3DAssets.dev is released under CC0 1.0 Universal, which places it in the public domain: use it in a paid game, an app, a film or a client project, modify it, redistribute it, and put nothing in the credits. A link back is welcome but it is entirely your choice.

CC0 licence text

Can I load it from the CDN instead of downloading it?

Yes. The pack behind it has a permanent URL on cdn.3dassets.dev that is CORS-enabled and never changes content, so you can pass it straight to GLTFLoader, glTFast or model-viewer in production and cache it as hard as you like. Downloading is only needed for engines that import from disk.

Is the demo itself a file I can download?

No, and it does not need to be. A demo is a layout of the pack's published models composed in your browser from the CDN, so there is no extra file to fetch. Download the pack for the models, and take the layout JSON linked above for the placements: together they are the whole scene, and an AI agent can rebuild it from those two links.

Can I change the scene, or add gameplay to it?

Yes. The layout is plain data in metres, so move, add or remove placements freely in your own engine. Colliders, navigation and gameplay are yours to add: the demo shows what the pack looks like assembled, and your game decides how it plays.
