Location and route

Plan a short route around Coral Gardens, plant routes. Check oxygen, tool power, food, water, and open inventory slots before leaving. When Fiber is found, return and sort it with related materials so the next recipe is faster to finish.

Uses and crafting value

Use Fiber for fiber mesh, rubber-like chains, early crafting. If it is part of an electronics or ingot chain, keep some raw ingredients unprocessed until the exact recipe is pinned in-game.

Risk and farming notes

Keep enough for equipment without filling storage. Early Access recipes can change, so verify the current Fabricator, Habitat Builder, or module interface before spending rare materials. In co-op, assign one player to resource calls and one to storage so duplicate runs do not waste oxygen.
