A board says "Not verified"
The solver hit its time or node budget before it could prove the solution count (common on
big, open grids). The board still plays — it just isn't guaranteed unique.
Coverage is the real uniqueness dial — a nearly-full grid has too many paths
to prove one unique (hex needs far lower coverage than square). For guaranteed-unique boards:
enable Require Unique and hit Auto (it sets a coverage your
grid can verify at), use a smaller grid, or raise
UniquenessSeconds / UniquenessNodeBudget.
Pink / magenta materials in the demo
That's the Built-in shader showing in a URP/HDRP project. The demo scene targets the
Built-in pipeline. Run Unity's material converter
(Edit ▸ Rendering ▸ Materials ▸ Convert…) on the demo materials. The generator
itself produces data, not visuals, so it's pipeline-agnostic.
No sound
The demo's audio (and UI clicks) need an AudioListener in the scene — it's normally on the Main Camera. If you made your own camera, add an Audio Listener component to it.
Compile errors right after importing
The demo uses the Input System and TextMeshPro packages.
Make sure both are installed (Package Manager) — TMP also needs its essentials imported
(Window ▸ TextMeshPro ▸ Import TMP Essential Resources). The Core generator has no
such dependencies; only the demo does.
Unity.InputSystem,
Unity.TextMeshPro, UnityEngine.UI).Mouse doesn't move the player
Movement is hold-and-drag: press the left button and drag over adjacent cells to draw the path (a single click only steps if you're exactly on an adjacent cell). The controller finds a camera automatically, so a missing MainCamera tag isn't the cause.
Hex keys feel wrong
Hex grids have six neighbors, so they use a corner-cluster — QE / AD / ZC — not WASD (there's no straight-up neighbor on a hex grid). Square grids use WASD / arrows. Dragging with the mouse works on both.
Pressing F does nothing
F resets the level and auto-plays the verified solution. It's ignored on an already-solved level. While it's playing, only R (cancel) responds — every other input is locked so it can't fight the playback.
