2. Click "Filter" and "Liquefaction" to open the Liquefaction Filter Settings window. You can also press the shortcut key shift+crtl+X.
3. Click the "Forward Deformation" tool on the left side of the liquefaction tool, adjust the size to cover the whole chest, hold down the left mouse button and drag in the material to push the chest to the left to make it bigger. The density and speed are the options of the pressure-sensitive pen, and there is no need to set them here.
4. Then click the "Smooth" tool to erase the part of the chest that is too prominent.
5. Click OK after adjustment to see the effect.
The chest was obviously bigger than before, and the breast enhancement operation was completed.
