A primitive authored with a rotation parameter spins about its own object origin, wherever it was placed, not about the part's intended pivot. A raked hood then see-saws about its own middle and shows half the intended wedge in each direction. Rotate the placement coordinate around the pivot first, then place the box there with the same rotation baked in, and remember that a rotated box's own bounding box is trigonometric, not its declared half-length.

Absolute-altitude biome thresholds tuned at one reference amplitude break when the slider moves -- the climate stack squashes or vanishes. Scale every altitude threshold by realized relief.

For a chunked runtime-mesh generator, REGEN (single-threaded generation CPU) is the binding resource, not fps or draw calls. Quartering the chunk count produces zero regen change; the lever is threading the passes.

The navmesh voxeliser erodes walkable surfaces by ceil(agentRadius/cellSize) whole cells on each side, so an opening narrower than that budget has no navmesh through it.
