Tile Canvas Save

Overview

Saves a TileCanvas document together with pinned snapshots of the assets it uses, keeping them consistent — the save path that makes a project folder reproducible offline on its own.

Usage tips

• Connect canvas from the tile-canvas editing node, and enable save_mode only for explicit saves.
• The saved .pxntilemap carries a project-relative fallback key referencing the same exact hashes as the snapshot index.
• Snapshot and index publication can happen before the main map file is written. If that final write fails, an unreferenced content-addressed snapshot may remain; this is safe and it can be reused by a later save or cleanup pass.

Common pitfalls

• A .pxntilemap alone is refs-only. It is not a self-contained distribution — keep the project assets with it.
• If a runtime asset at the exact pinned hash is missing, the snapshot cannot be pinned and the save fails; resolve the missing asset and retry.
