Drawing: Cover the terrain according to the set size strength, size, attenuation radius, and layers.
Smooth: It is most used at the junction of the front and back layers, so that there is a transition effect between the two layers.
Flat: In this mode, the brush color has nothing to do with the selected layer color, and the brush color is related to the color you pick up when you click on the ground for the first time. The terrain is divided into area blocks. If the setting is appropriate, the area block will be filled with flat mode without affecting other area blocks.
Noise: The fill effect is a noise effect.
