In the unforgiving world of Sons of the Forest, resource management and construction skills determine survival. Planks, derived from logs, form the backbone of sturdy bases, enabling everything from defensive walls to elevated platforms. This guide explores the complete process of creating planks and deploying them effectively across various builds.
Understanding Logs and Their Role in Construction
Logs serve as the primary building material, obtained by felling trees with an axe. Full-length logs can be segmented into halves (planks), quarters, or smaller pieces, each with specific applications. Planks—essentially halved logs—offer versatility for flat surfaces like floors and roofs, while smaller cuts support detailed framing.
To harvest logs, equip your axe and strike tree trunks repeatedly until they topple. Collect the resulting logs by interacting with them (E on PC, or equivalent controller input). Position logs on flat terrain to prevent rolling, as uneven ground complicates processing.
Step-by-Step Guide to Producing Planks
Transforming a log into planks requires precise axe work. Follow these steps for reliable results:
- Place a full log on level ground, facing its end.
- Equip any axe; smaller axes like the craftable one aid precision for beginners.
- Align your view along the log’s length until a red dotted line appears, indicating the cut path.
- Press the attack button (left mouse or trigger) to execute the lengthwise chop, splitting the log into two planks.
This method yields two usable planks per log. For quarters, repeat on a plank until a red line reappears for finer cuts. Practice on open areas to master alignment, as hills or clutter can disrupt the process.
| Log Type | Cut Method | Output | Best Use |
|---|---|---|---|
| Full Log | Lengthwise chop | 2 Planks | Floors, Roofs |
| Plank (Half Log) | Lengthwise chop | 2 Quarter Logs | Framing, Supports |
| Quarter Log | Cross chop | Firewood/Sticks | Crafting, Fuel |
Building Foundations with Planks
Foundations provide a stable base, especially on slopes. Start by planting vertical logs: hold a log, right-click to cycle placement modes until a white dashed circle appears on the ground, then left-click to set. Connect multiple verticals with dashed lines for even spacing.
For a basic square foundation:
- Plant four vertical logs in a square.
- Fill the interior with five planks, snapping them into place automatically.
Use varying log lengths to level uneven terrain. Quarter logs fine-tune alignment, ensuring structural integrity.
Constructing Walls for Defense
Stack full logs vertically atop foundations or ground for walls six logs high—no side supports needed. Approach the edge holding a full log; a white rectangle prompt confirms placement.
Planks aren’t primary for walls but reinforce interiors. Cannibals and mutants can climb these barriers, so combine with traps for security. Build taller variants by extending beyond six logs where terrain allows.
Floors and Roofs: Expanding Upward
Floors mirror foundations: four corner verticals filled with five planks. Roofs demand more planning.
Roof framework:
- At wall corners, attach diagonal logs to vertical supports.
- Prop the free end with another vertical.
- Fill gaps with planks, mimicking floor layout.
Slanted roofs use parallel diagonals, covered by eight planks (or four full logs auto-split). Ensure even spacing to avoid gaps vulnerable to weather and enemies.
Ramps and Stairs for Accessibility
Navigate elevations with ramps or stairs. Ramps: position two parallel diagonal logs between verticals, then add eight planks. Steeper angles use full-height supports; shallower ones shorter logs. Note: 45-degree ramps cause sliding—use for roofs or cautious traversal.
Stairs require struts: halve a log, approach a diagonal-over-vertical setup for a placement prompt. Repeat for both corners, then plank the steps. These provide stable footing without slip risks.
Doors and Windows: Functional Openings
Carve doors/windows from completed walls. Axe out mid-wall sections; windows need no extras, while doors require two logs for three-plank framing. Position centrally for easy access; reinforce frames to prevent collapse.
Advanced Tips for Efficient Building
- Companion Assistance: Command Kelvin to haul logs or build, speeding construction.
- Simplified Mode: Add logs to blueprint structures—they auto-convert to needed pieces.
- Resource Optimization: Chop extras into firewood; store surplus in drying racks.
- Defense Integration: Embed spikes or defensive walls during plank placement.
Experiment with hybrid designs: elevated platforms combine foundations, ramps, and roofs for cannibal-proof lookouts.
Common Mistakes and Troubleshooting
Avoid these pitfalls:
- Misaligned red lines: Reposition for flat, lengthwise view.
- Rolling logs: Dig shallow trenches or use flat spots.
- Unstable builds: Verify snapped placements via dashed indicators.
- Axe choice: Modern axe excels for speed, but craftable suffices early-game.
If planks won’t form, ensure log stability and correct angle. Reload saves rarely needed—patience refines technique.
Why Planks Matter for Long-Term Survival
Beyond aesthetics, plank-based bases withstand storms, mutant assaults, and resource scarcity. Multi-level forts with ramps grant vantage points; walled compounds protect farms and workshops. As you progress, planks enable custom mega-structures, turning the peninsula into a fortress.
Iterate designs: start simple (lean-tos), scale to villages. Track wood via inventory; replant trees for sustainability.
Frequently Asked Questions (FAQs)
Q: Do I need a specific axe for planks?
A: Any axe works; smaller ones help alignment.
Q: Can planks be used in blueprint mode?
A: Yes, logs auto-convert—no manual splitting required.
Q: How many planks per foundation?
A: Five for a basic square floor.
Q: Why do ramps make me slide?
A: 45-degree angles cause this; opt for stairs indoors.
Q: Are walls cannibal-proof?
A: They climb but slowly; add defenses.
Strategic Base Locations
Beachfronts offer flat ground and fishing; forests provide wood but hide threats. Caves near water balance resources. Scout with GPS before committing planks.
