Large rocks
Build Stronger Terrain
Large rock starts two sizes above the small-rock ending for the selected modeling scale.
Large-Rock Guide
Larger grades create stronger texture in cuts, canyon floors, bridge approaches, dry washes, and embankments.
| Rock size | N scale | HO scale | O scale | G scale |
|---|---|---|---|---|
| Large rock | ends in 5+ | ends in 6+ | ends in 7+ | ends in 8+ |
The plus sign means larger endings can also work. Partially bury the biggest pieces and blend their edges with medium rock and gravel.
