Dragon lair valley
Walk a 78 by 64 metre dragon lair valley: an elder settled on its hoard before a cave mouth, a nest ground of eggs and hatchlings, a feeding ground of bone, a basking shelf of wyverns, and every dragon in the pack at its own scale.
About
All 61 individual models in the pack, laid out as one dragon lair valley 78 by 64 metres under a dusk sky. Every dragon here is a fictional creature described by type, age and pose: no dragon from any film, book, game or television series is referenced, and no individual creature is named.
You start at the mouth of the valley looking north along a drift of spilled coin. At the end of it an elder dragon sits settled on its hoard, eleven metres of it, with the cave mouth arch standing thirteen metres wide behind. Eleven hoard piles, six treasure chests and scattered gold spread out around the elder, and a second elder roars to the west while a third stands to the east. An adult rears on one side of the approach and another roars on the other, so the walk in passes between them.
West of the hoard is the nest ground: nine nests of eggs, five clutches on rock and better than forty eggs whole, cracked and hatching, with the three hatchlings among them, two juveniles at the edge and an adult perched over the lot with its wings folded. East is the feeding ground, thirteen gnawed bone piles, five dragon skulls and scorched patches, where one adult feeds and another crouches ready to spring, with a slain adult at the north edge.
The west ridge is a basking shelf of perch rocks with a wyvern up on one, another standing alert, a third crouched and a fourth holding the ridge with a 12.9 metre wingspan. Before the cave an eastern dragon lies coiled, a second sleeps further west and a third rears to the east. The south west quarter is the wingless one, four drakes and three lindworms at a size a person could face, and the south east corner is a captor's: an iron cage, a chain and shackle anchor, a drake crouched beside it and a slain wyvern. By the spawn a display plinth carries a 1.75 metre reference figure on a turntable, so the first thing you can do is judge the sizes: hatchling 0.6 m, juvenile 2.6 m, drake 2.8 m, lindworm 5.4 m, wyvern 6.2 m, adult 7 m, eastern 9.5 m, elder 11 m. Two more reference figures stand by the hoard and by the nests for the same reason. Claw mark plates, shed scale piles, coin and bone are worked out across the whole floor, which is laid from repeated lair ground tiles. Placing the whole pack costs the visitor about 10 MB of GLB across 61 downloads, which is the trade for a valley with every design in it.
What moves: the treasure chest lids open and close, the iron cage door opens and closes, and the display plinth turntable spins. That is the whole of it.
What does not move, and why: every dragon, wyvern, drake, lindworm and hatchling is static geometry in a baked pose. The pipeline has no skinning, so wings, necks, tails, jaws and flame cannot be driven by a rigid node transform, and hinging a limb node off a creature's body reads worse than a clean pose does. The five flying poses hang over the rock at the valley edges and over the cave forecourt as scenery rather than as animation, and the walk has no vertical movement, so everything you are meant to meet stands on the ground.
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
The elder over its hoard
An 11 metre elder settled on its gold, with hoard piles, five chests and coin spilling down the valley. The chest lids open as you come near. The cave mouth stands behind it.
Elder Dragon Settled On A Hoard (Dragons and Wyverns)How big is a dragon
A 1.75 metre figure on the turntable gives you the scale: hatchling 0.6 m, juvenile 2.6 m, drake 2.8 m, lindworm 5.4 m, wyvern 6.2 m, adult 7 m, eastern 9.5 m, elder 11 m. The turntable spins.
Display Plinth With A Turntable (Dragons and Wyverns)The nest ground
Nine nests, five clutches on rock and forty odd eggs whole, cracked and hatching, with three hatchlings and two juveniles among them and an adult perched over the lot with its wings folded.
Dragon Nest Of Eggs (Dragons and Wyverns)The feeding ground
Gnawed bone piles, skulls and scorched ground east of the hoard, where an adult feeds and another crouches ready to spring. A slain adult lies at the north edge of it.
Western Dragon Feeding (Dragons and Wyverns)The basking shelf
Four perch rocks on the west ridge with a wyvern up on one, another standing alert below and a third crouched to spring. A wyvern with a 12.9 metre wingspan holds the ridge line.
Wyvern Perched (Dragons and Wyverns)The cave mouth
A 13 metre arch closes the north end, coin and shed scale trailing out of it. An eastern dragon lies coiled before it, another asleep further west and a third reared up to the east.
Eastern Dragon Coiled (Dragons and Wyverns)The captor's corner
An iron cage whose door opens, a chain and shackle anchor set in the ground, a drake crouched beside it and a slain wyvern north of it. Somebody here kept dragons, and it went badly.
Iron Cage With An Opening Door (Dragons and Wyverns)Drakes and lindworms
The wingless quarter, south west: four drakes standing, walking, crouched and curled asleep, and three lindworms standing, coiled and reared, all at the size a person could face.
Lindworm Rearing (Dragons and Wyverns)
