Runtime terrain meshing: chunked greedy voxel/heightfield terrain

The method for large runtime-generated terrain in s&box: a persistent cell grid as the single source of truth, chunked greedy meshing (tops + skirts), collision decoupled from render grain, palette-atlas UVs, and dirty-chunk remesh for a live terrain brush.

"Greedy voxel mesher produces vertical stripes on cliff faces instead of horizontal strata"

Per-cell dither or contour-wander in a greedy voxel mesher turns cliff skirts into vertical stripes: detect walls and key strata on raw height bands with dither neutralised.

"Ground overlays z-fight each other, and a full-lap overlay z-fights itself"

Lifting a flat overlay clear of the ground is only half the rule. Overlays also z-fight each other, and a full-lap overlay on a self-crossing path z-fights itself, which no single lift value can fix.

"Per-cell white noise hash gives salt-and-pepper terrain instead of organic shade patches"

A per-cell white-noise hash for terrain shade choice reads as a 50/50 checkerboard. Use a smooth low-frequency noise field instead, confining the hash to threshold-edge dithering.

"Projected decals conform to runtime model renderers"

A Sandbox.Decal projects onto runtime-built chunk meshes (ModelRenderers) and conforms to stepped/curved faces, confirmed live on voxel terrain.
