If a type layer or a shape layer is selected, you must rasterize the layer before proceeding, making the type or shape editable by the Liquify filter. To distort type without rasterizing the type layer, use the Warp options for the Type tool. Select the layer you want to distort. To change only part of the current layer, select that area. Choose Filter > Liquify. Prerequisite: Enable the graphics processor As a prerequisite to using Face-aware Liquify functionality, ensure that the graphics processor is enabled in your Photoshop preferences. Choose Edit > Preferences > Performance. In the Graphics Processor Settings area, select Use Graphics Processor. Click Advanced Settings. Ensure that Use Graphics Processor To Accelerate Computation is selected. Click OK. These settings are enabled by default when you launch Photoshop for the first time. If you have questions regarding GPU usage in Photoshop, consult this document. Distortion tools Several tools in the Liquify dialog box distort the brush area when you hold down the mouse button or drag. The distortion is concentrated at the center of the brush area, and the effect intensifies as you hold down the mouse button or repeatedly drag over an area. Forward Warp tool Pushes pixels forward as you drag. Note:Shift-click with the Warp tool, the Push Left tool, or the Mirror tool to create the effect of dragging in a straight line from the previous point you clicked. Reconstruct tool Reverses the distortion you’ve already added, as you hold down the mouse button and drag. Twirl Clockwise tool Rotates pixels clockwise as you hold down the mouse button or drag. To twirl pixels counterclockwise, hold down Alt (Windows) or Option (Mac OS) as you hold down the mouse button or drag. Pucker tool Moves pixels toward the center of the brush area as you hold down the mouse button or drag. Bloat tool Moves pixels away from the center of the brush area as you hold down the mouse button or drag. Push Left tool Moves pixels to the left when you drag the tool straight up (pixels move to the right if you drag down). You can also drag clockwise around an object to increase its size, or drag counterclockwise to decrease its size. To push pixels right when you drag straight up (or to move pixels left when you drag down), hold down Alt (Windows) or Option (Mac OS) as you drag. Distortion tool options In the tool options area of the dialog box, set the following options: Brush Size Sets the width of the brush you’ll use to distort the image. Brush Density Controls how a brush feathers at the edge. An effect is strongest in the center of the brush and lighter at the edge. Brush Pressure Sets the speed at which distortions are made when you drag a tool in the preview image. Using a low brush pressure makes changes occur more slowly, so it’s easier to stop them at exactly the right moment. Brush Rate Sets the speed at which distortions are applied when you keep a tool (such as the Twirl tool) stationary in the preview image. The higher the setting, the greater the speed at which distortions are applied. Stylus Pressure Uses pressure readings from a stylus tablet. (This option is available only when you are working with a stylus tablet.) When selected, the brush pressure for the tools is the stylus pressure multiplied by the Brush Pressure value.
