nxCover

Set as Sequence, by default, this dropdown menu gives options for establishing how the particle will move onto the next object.
设置为序列 ，默认情况下，此下拉菜单提供用于确定粒子如何移动到下一个对象的选项。

The other options are: Nearest Object, Furthest Object, Object Index and Random Object.
其他选项包括： 最近的对象 、 最远的对象 、 对象索引和随机对象 。

Particles will move onto the next object in the node tree.
粒子将移动到节点树中的下一个对象。

Particles will move onto the nearest object in the scene.

Particles will move onto the furthest object in the scene.

Particles will move onto the object index (indexed from the node tree).

Particles will move onto a random object in the node tree.

If Sequence is chosen as the Object Mode, this option allows the modifier to continue looping over the modifier’s object more than a single time.

A list of objects dragged and dropped from the Objects Manager.

Set as Polygon Area, by default, this dropdown menu gives choices for cover operation.

The alternative options are: Polygon Center, Points, Edges, Particle Ray, Object Volume and Texture.

Surface of a polygon.

Center point of a polygon.

Points or vertices on a surface.

Edges on a surface.

Within the particle path.

Within an object’s volume.

Based on a texture above or below a certain threshold.

Selection map of the object (edges, points, polygons and vertex maps are supported).

Choose either Shader or Texture Tag to reveal further parameter options.

Link to the shader or texture, depending on the dropdown choice chosen in Texture Source.

Only available when Texture Source is set to Texture Tag,

Set as 128, by default, this dropdown box changes the resolution of the sampling of the texture/shader.

The available presets are: 64, 128, 256, 512, 1024 and 2048.

Resolution parameter options.

The texture tolerance slider adjusts the minimum of the shader sampling.

Lower tolerance allows darker areas and higher tolerance would allow only lighter areas (no darker).

Color to be used for the texture sampling threshold.

Dropdown option to choose sampling mode (either Texture Color >= Threshold or vice versa).

Maximum number of attempts for the particle to sample the shader in random positions and find a suitable position.

Slider for force used.

Note: This is only if Speed Mode is set to Use Speed.

Distance from cover position at which the particle will start the holding.

Again, only if Speed Mode is set to Use Speed.

When enabled, all options below this will be inherited from the next up within the node tree which doesn't have this checked.

Image to demonstrate the Inherit Parent parameter (checked), in the red box.

Checkbox to allow the modifier to align the up vector of the particle to the normals of the surface.

A strength slider which impacts how much change the normal alignment will have.

Check this box to change the color on cover hold.

A checkbox which is only available when Operation is set to Texture, which allows the user to set the color to the color of the texture on cover.

Blend timing slider.

Color selection for the color to change to.

A checkbox to enable the option to change the color on release.

The color to be set on release.

In this image, the Release Color is set to blue.

Set as Use Speed, by default, these are modes for how the particle moves to its cover position.

The alternative is Time to Target.

Uses a speed variable.

A fixed time to move to the target.

Set as Particle, by default, this is a dropdown menu for what speed to use.

The other options are: Fixed and Force.

Use the speed of the particle.

Use a fixed speed.

Use a force towards the cover position.

If the Speed Type of Fixed is selected, use this slider to set the speed used for the particle to move.

How long the particle will hold on that position, once arrived.

Adds a variation to the Hold Time amongst particles.

How the particle behaves while covering the object.

Set as Attract, by default, these are modes for the particle’s behavior when holding.

The alternative settings are: Free, Spring and Stick.

Attract force towards the cover position.

This mode enables five additional parameters (below).

Set as Velocity, by default, this is how the particle behaves when ‘holding’ on the point.

The alternative setting is Force.

New force is added to the existing velocity.

New force is set as velocity.

Set as Slowdown, by default, where the movement will get slower closer to the point.

The alternative setting is Attract, where movement will stay active and constantly be attracted to the point.

The distance at which the attraction slowdown will start.

The minimum and maximum speed of the particle for both Slowdown and Attract modes.

Free movement after arriving at the cover position.

Spring forces towards the cover position.

This mode enables three additional parameters (below).

The length of the spring.

The stiffness of the spring.

Spring damping.

Stick to cover position.

Check this box to enable the breaking forces.

Distance at which the breaking force from the cover position begins.

Minimum and maximum speeds during the breaking.

Use this spline to customize the speed during the breaking force.

To specify the group, drag and drop the desired Group object into this field.

This setting is useful if you want to ensure that the spawned particles are, or are not, affected by nxCover.

The modifier’s settings can be mapped to particle data.

Use the dedicated manual page, below, for instructions on how this works.

You can use the Fields options to control where nxCover operates.
