it brings the core function: mask painting and saving.
So you can easily customize any shape.
1. Convenient and flexible mask drawing
2. Wave bounce optimization (ripple will bounce when it hits the edge of the mask)
3. Support shortcut toggle.
How to use mask drawing:
1. check "Enable Mask Painting".
2. When the mouse pointer comes to the water, a white circle will appear. LMB hold and drag to draw incrementally. Shift+LMB is erasure.
3. You can save the drawn Mask by "Save Paint Mask".
4. With the "Start With Full Mask" switch, you can set the starting point of drawing (all erase/no erase at all).
Suggestion: If you only need a small water body, it is strongly recommended to scale the water body area (width/height) first, and then draw the mask.
