Tile set load failed!

Error message

Tile set load failed!

What it means

After the tile set resource future resolves, TileBrush::block_until_tile_set_is_loaded also checks the loaded TileSet for internal errors (is_ok); if the tile set content itself is in an error state, it logs 'Tile set load failed!' and returns false.

Solutions

1. Inspect the tile set resource state for its inner error and fix the .tileset file contents.
2. Re-create the tile set in the editor and re-link it to the brush.
3. Re-save the tile set with the current Fyrox/editor version.
4. Validate any externally generated .tileset data against the current format.

if !brush.block_until_tile_set_is_loaded() {
    // inspect tile set resource state for the inner error
    return;
}

When it happens

Trigger: block_until_tile_set_is_loaded when the tile set resource loads but its payload is an error (e.g. deserialization of tile set contents failed).

Common situations: Tile set file exists but has invalid/corrupt contents; tile set saved by an incompatible Fyrox version.

Understand the failure class

Background: Schema validation failed / invalid input schema: payload rejected because its shape doesn't match the expected schema — this error's family across 28 libraries.
