Break a Dune with an ordinary digging tool and it drops Sunsand. The official Wiki says Sunsand turns back into Dune when it is not falling, so a pit or a stopped pile is not a permanent Sunsand store. The cited v0.5.0 recording shows the same break, fall, and reformation sequence.

Sandustry Dune Guide: Sunsand Drops, Mining & the Reform Rule
Dune is desert terrain, not a permanent loose-material deposit. The official Wiki describes a simple loop: destroy a Dune, observe the Sunsand it yields, and expect that Sunsand to turn back into Dune when it is no longer falling.
Quick answer
Dune becomes Sunsand only while it falls.
What the evidence supports
Watch the state change,
not the hole.
01 · Find the terrain
The official Dune entry places Dunes in the desert. It records 1 HP and says ordinary digging tools can dig them; no special required tool is published.
02 · Break one Dune
Destroying a Dune yields Sunsand. The material is a temporary state rather than a normal mined stockpile, so observe it immediately after the break.
03 · Follow the falling Sunsand
The official Sunsand entry says it is dropped by Dune. The community recording shows the released pixels moving downward after the terrain is broken.
04 · Expect Dune to return
The official rule is explicit: Sunsand turns back into Dune when it is not falling. The return is the expected end of the visible cycle, not proof that the dig failed.
05 · Keep collection claims narrow
Sunsand is officially marked Launchable, but the local official page does not promise a permanent collection route, a timing window, a yield, or a Launcher layout. Test any current-build setup before treating it as a farm.

These user-authorized frames document one v0.5.0 community playthrough recorded on 8 August 2026. They illustrate the Dune-to-Sunsand cycle; the official Dune and Sunsand pages remain the source for the general material rules.
The Dune tooltip in the recording shows 1 HP. The official Dune entry independently lists 1 HP and says usual digging tools can dig it.
The player observes Sunsand after breaking the Dune. The official Sunsand entry identifies Dune as its source.
The recording shows the dug space closing as the material returns. The official rule is that Sunsand becomes Dune when it is not falling.
This is a useful failure-state reference: a visible hole can disappear as Sunsand stops falling and the Dune reforms. It does not prove a collection-rate or tool limitation.

Source Wiki
- The official Dune page says Dunes occur in the desert, have 1 HP, can be dug with usual digging tools, and yield Sunsand.
- The official Dune page says its Sunsand quickly returns to Dune. The official Sunsand page states the same condition precisely: Sunsand turns back into Dune when it is not falling.
- The official Sunsand entry marks Sunsand as Launchable, not Burnable, and not Wettable. It does not publish a collection rate, time limit, or permanent storage method.
Community-tested
- Twisted - HoneyBunnyGames, 35:25-35:33: the player identifies Sunsand as Dune material and observes that it reassembles.
- The attempted Grabber interaction and the later weapon shot in the supplied frames are not used as general Dune rules: one is only a single attempt, and the later shot is near the Pyramid rather than a controlled Dune test.
These are useful player examples, not official specifications.
