-A performant way to render tilemap chunks has been added as the first building block to Bevy's tilemap support. You can render a chunk by supplying a tileset texture to the `TilemapChunk` component and the indices into that tileset for each tile to `TilemapChunkIndices`.
+A performant way to render tilemap chunks has been added as the first building block to Bevy's tilemap support. You can render a chunk by supplying a tileset texture to the `TilemapChunk` component and tile data to `TilemapChunkTileData`. For each tile, `TileData` allows you to specify the index into the tileset, the visibility, and the color tint.
 
 ```rust
 let chunk_size = UVec2::splat(64);
-let tile_size = UVec2::splat(16);
-let indices: Vec<Option<u32>> = (0..chunk_size.x * chunk_size.y)
+let tile_display_size = UVec2::splat(16);
+let tile_data: Vec<Option<TileData>> = (0..chunk_size.element_product())
     .map(|_| rng.gen_range(0..5))
-    .map(|i| if i == 0 { None } else { Some(i - 1) })
+    .map(|i| {
+        if i == 0 {
+            None
+        } else {
+            Some(TileData::from_index(i - 1))
+        }
+    })
     .collect();
 
 commands.spawn((
     TilemapChunk {
         chunk_size,
-        tile_size,
+        tile_display_size,
         tileset,
     },
-    TilemapChunkIndices(indices),
+    TilemapChunkTileData(tile_data),
 ));
 ```
