The shape that works
Obby terrain should look dramatic from a distance and stay out of the way up close —
sheer cliffs around your stage, themed biomes that match your stage name, and a "floor"
deep enough that falling feels like a real loss.
- Vertical drama (steep walls, deep voids) for visual stakes.
- A flat-ish anchor point where you place your start and stage parts.
- Themed biome that matches your stage name — Lava Stage = volcano, Frost Stage = glacier.
- Don't compete with your parts — terrain should frame, not distract.
Prompts that ship
Volcano stage
$terrain "active volcano with lava rivers, black rock cliffs, ash plumes — dramatic"
Ice peak stage
$terrain "single jagged ice mountain rising from frozen sea, sheer cliffs"
Jungle ruin stage
$terrain "deep jungle valley with rocky outcrops and ancient ruins, mossy"
Common questions
Should I generate the obby itself?
No. Terrainio makes terrain, not platforming jumps. Generate the backdrop, hand-author the parts. The two layer cleanly.
How tall should the terrain go?
For obbys, vertical drama matters. 200–400 studs of vertical range gives "I'm climbing a real mountain" feel without breaking camera defaults.
