Dynamic Plug-ins : Applying the Liquid Metal dynamic plug-in
Quick links to procedures on this page:
The Liquid Metal dynamic plug-in lets you paint on a layer with liquid and metal. This text uses the term "metal" to refer to the media applied — even if the settings create an effect more like water.
You can apply droplets of liquid that distort the underlying image through refraction. You can also create globs of shiny metal that flow together and move like mercury. The Refraction slider sets the difference between water and metal, which lets you achieve intermediate effects. Negative metal can be used to create holes in metal.
The Liquid Metal dynamic plug-in creates either liquid metal or translucent, refractive liquid.
A stroke of metal is made up of a series of discrete droplets. You can select one or several droplets and move them or change their properties.
The "handles" show the droplet’s circle and center point. Showing the handles on the droplets isn’t necessary for selecting them, but it can make your work easier. The droplets applied in the last stroke are automatically selected. Each new stroke deselects the droplets of the previous one.
The Undo feature is not available when working with metal; however, you can remove selected metal, the last metal applied, or all metal on the layer.
Metal is highly reflective. You can customize the look by using a clone source or a pattern as a reflection map. For more information, see Image cloning and sampling and Patterns.
Liquid metal tools
You can apply metal with the Brush tool, the Circular Drop tool, or the Rain feature. You can adjust the size of your brush or rain droplets. The Brush is the default applicator. You can use the Brush tool to paint with metal. You can use the Circular Drop tool to create circles of metal. The Rain feature lets you scatter metallic droplets on the layer.

In the Layers panel, choose the Canvas. |

|
Click the Dynamic Plug-ins button  , and choose Liquid Metal. |

In the Liquid Metal dialog box, choose one of the following tools: |
|

|
In the Settings area, move any of the following sliders: |
|
• |
Size — changes the diameter of the selected droplets that you apply by using the Brush tool or Rain. It does not affect the Circular Drop tool. |
|
• |
Spacing — adjusts the spacing between droplets in strokes created with the Brush tool |
A stroke with low spacing (left): the droplets flow together. A stroke with high spacing (right): each droplet is distinct.
|
• |
Volume — adjusts visibility along the perimeter |
Decreasing volume below 100% shrinks the visible portion of the droplet, "drying it up" (left). Increasing volume beyond 100% extends visibility beyond the droplet circle into the perimeter range (right).
|
• |
Smooth — changes the perimeter range, which determines the droplet’s tendency to "join" its neighbors |
Low settings on the Smooth slider keep droplets distinct (left); higher settings make the droplets flow together (right).

In the Rendering area, choose one of the following metal types from the Map list box: |
|
• |
Amount — controls the emphasis of the metal effect from the Refraction slider and applies to all droplets in the layer. To create water effects, you can set the Amount to –0.5 so the droplets magnify the underlying images. |
Reflection and Refraction are inverted when you move the Amount slider to either extreme.
|
• |
Refraction — controls droplet appearance. The slider represents a scale between reflection and refraction. |
Low refraction means high reflection (left). High refraction creates translucent, refractive liquid. As Refraction nears 100%, the metal becomes transparent. The droplets look like a simple liquid — oil or water (right).

|
|
|
Enable the Surface tension check box.
|
|
|
In the Liquid Metal dialog box, click Rain, then click anywhere in the image to stop the rain.
If Smooth and Size settings are very high, the rain might continue for a moment after you click.
|
|
|
|
The Map type that you choose applies to the entire layer. You can change the type at any time.
| • |
Press Option (macOS) or Alt (Windows), and drag with the Circular Drop tool  or Brush tool  over existing metal droplets. |
|
|
|
|
|
Press Delete (macOS) or Backspace (Windows).
|
|
|
In the Liquid Metal dialog box, click the Select Drops tool  , select the metal, and press Delete (macOS) or Backspace (Windows).
|
|
|
In the Liquid Metal dialog box, click Clear.
|
| • |
In the Liquid Metal dialog box, enable the Display handles check box. |
When you enable the Display Handles check box (right), you can see the droplet circles and center points.
|
1
|
In the Liquid Metal dialog box, choose the Select Drops tool . |
|
|
|
|
|
If the Display Handles check box is enabled, click the center point handle of a droplet. If handles are not displayed, click anywhere on a droplet.
|
|
|
|
|
|
Hold down Shift, and click additional droplets to add to the selection.
|
|
|
Hold down Shift, and click droplets to subtract from the selection.
|
When a droplet is selected, the center point handle is displayed as a solid.
Drag over the droplets you want to select.
|

|
In the Liquid Metal dialog box, choose the Select Drops tool , and select the droplets that you want to move. |
|
2
|
Choose the Move Drop tool, and drag the droplets to a new position. |
You can drag the center of one of the droplets to move the selected group.
|

|
In the Liquid Metal dialog box, choose the Select Drops tool , and click outside the droplets to deselect all. |
|

|
Move the Size slider to the desired value. |
|

|
Click the Brush tool and paint, or click Rain. |
You can also adjust the size of existing metal by selecting the droplets and moving the Size slider.

|
In the Layers panel, click the Dynamic Plug-ins button , and choose Liquid Metal. |
|

|
In the Liquid Metal dialog box, choose Clone Source from the Map list box. |
If no clone source has been specified, Corel Painter uses the current pattern as the reflection map.
The same piece of metal changes appearance when a pattern is used as the reflection map.
