Capture Layer Paint surface node

Lets you paint capture attributes directly onto geometry.

Capture Layer Paint is a specialized paint operation for painting capture attributes.

Using Paint Capture Layer

Click the Paint Capture Layer tool on the Character tab.
Select the geometry to paint and press Enter to confirm your selection.
Click the bone to select the capture region.
Drag the brush over the surface to paint it.

Note

You can modify the Radius and Opacity on the operations toolbar.

Parameters

Capture Type

The type of capture (the attribute) to modify.

Bone	Modify the `pCapt` point attribute when painting.
Metaball	Modify the `metaCapt` point attribute when painting.

Operation

Group	Specifies a subset of points to affect. If this is blank, all points are affected.
Group Type	The type of geometry to use in the group. If the group has only one type of geometry (for example, points), you can just use “Guess from group” and Houdini will figure out the geometry type from the contents of the group.
Operation	The operation used by Apply To All.
Default Skeleton Root Path	Default prefix applied to capture region paths if none is supplied by the geometry.
Capture Region	The capture region to paint.
Maximum Paint Value	The maximum value of a capture weight that can be reached in the layer using the paint operation.
Minimum Reduce Value	The minimum value of a capture weight that can be reached in the layer using the reduce operation.
Apply To All	Applies the operation to all of the selected geometry.
Reset All Changes	Restores the geometry to its initial state.
Flatten Layers	Updates the layer to contain a snapshot of the current capture weights.
Visualize Attribute	Whether to visualize the capture weights by coloring the geometry.
Visualize Normalized Weights	Indicates the visualized weight values should be normalized.
Visualize Layer	Whether to visualize the weights in the layer or the result after compositing.
Visualize	Whether to visualize weights for the selected capture region or all capture regions.
Visualize Mode	For single bone, how to map the weight to a color.

Brush

Shape

The basic shape of the brush: circle, square, or bitmap.

Bitmap

What bitmap to use. The alpha channel becomes the brush.

Radius

The radius of the brush when painting in the 3d viewport.

UV Radius

The radius of the brush when painting in the 2d viewport.

Radius Pressure

This controls how much effect the pressure of a stylus will have on the radius. A value of 1 means the radius will go from 0 to the amount in Radius. A value of 0 will mean the radius will always be constant, regardless of pressure. A value of 0.5 will mean the radius will be scaled between one half of Radius and Radius.

Depth

If set, this limits how far the brush will paint along its axis. This can be used if connectivity is disabled to limit the effect of the brush. The first parameter is how deep below the surface the brush should penetrate. The second is how high above the surface it should stop. These values can be negative.

Brush Angle

How far to rotate the brush.

Brush Squash

Amount to squash the brush in the y direction before rotation.

Opacity

The amount to affect the stencil mask.

Opacity Pressure

This controls the how much effect the pressure of a stylus will have on the opacity. It obeys the same scaling as the Radius Pressure.

Brush Splatter

A random noise in the brush’s opacity based upon the position on the brush.

Paper Grain

A random noise on the object’s stencil mask based on the object position.

Soft Edge

Percentage of the brush to be rolled off.

Kernel Function

Which metaball kernel to use for the roll off.

Up Vector Type

How the brush should be oriented on the surface:

Stroke Direction	Oriented in the direction in which the brush moves.
Fixed	Oriented as specified in the Up Vector field.

Up Vector

The fixed up vector to orient brush to.
