What is the difference between the Normal and Free mode in Tile Flooring?

Click "Customize-Tile Flooring" and select the wall or floor to enter the tile flooring interface. You can switch between the "Normal" and "Free" modes in the upper right corner. In the "Normal" mode, you can quickly design the paving or flooring of the surface as a whole by dragging tile patterns. In the "Free" mode, each floor tile (or wall tile) can be tiled or paved individually, so as to create a more flexible and customized tiling or paving or flooring effect.
