Safety Guarantee: Partner materials and independent transitions (e.g. Sand ↔ Water) will not be deleted or damaged.
Delete Collection Image
Are you sure you want to delete Image?
From tileset: Collection
Warning: This will permanently delete the image asset, discard all custom gameplay properties assigned to it, and remove all placed instances of this object across the entire map.
Extrude Tileset (Fix Texture Bleeding & Seams)
What does Extruding do? Extrusion duplicates the 1px edge and corner pixels of each tile into surrounding padding borders. This eliminates texture bleeding seams when zooming or panning cameras in Phaser, Godot, PixiJS, Unity, etc.
Note: Any missing texture will create a placeholder tileset without polluting your Project Assets Vault. You can upload missing images at any later time to automatically connect them and populate the map.
