Log cabin in a sunlit Pacific Northwest forest

Opus 5.5 has once again destroyed my expectations for games and 3D modeling. A full survival game like The Forest, in three.js, in 1 day of continual work. A 2 km island carved by simulated erosion. 44,000 trees, every one generated in code and wrapped in real photoscanned bark. Six real Pacific Northwest species. The sun and moon sit where they really would at 49 degrees north in late September. Thunder arrives late because it travels at the speed of sound. Wolves stalk at dusk, circle the fire at night and back off from a torch. Claude Code split the world between waves of agents, one per domain, and critic agents that never touched the build checked the renders against real photos. 62 seconds of 4K, 1,881 frames, rendered one by one out of the game itself. The wolf is still the weakest thing in it and it doesnt hold 60 fps yet. I ran out of Claude usage before the realism pass finished. Its not even done.
