| tileX | Tile X coordinate. |
| tileY | Tile Y coordinate. |
| miplevel | Mipmap level of the texture. |
| data | Tile color data. |
Update sparse texture tile with color values.
This function makes a tile at (tileX,tileY) coordinates resident in memory, and updates its pixels. If a tile is already resident, then only the pixels are updated.
Data passed should have enough pixels for the tile (tileWidth*tileHeight elements). Exception can be small mipmap levels that are smaller than tile size; then it's ok to pass enough data for the mip level size.
UpdateTile only works for non-compressed color formats. If you use a sparse texture with a compressed format, use UpdateTileRaw and pass raw tile data bytes (e.g. DXT-compressed data). UpdateTileRaw can also be more efficient if texture format is not RGBA32, as then Unity does not have to convert from Color32 data into the underlying texture format.
