Customizing or Making Your Own Cluster FX
In the previous section of the manual, we learned about the process of adding The Cluster layers [?]
Layers are containers for visual, audio or layout items and are added to slides. For example, text, button, image, audio, video, group and row are all types of layers.
Layers are added to slides via the module editor. to a slide.
Once you’ve added a cluster layer, there are numerous ways to personalize it according to your module’s [?]
A module in Slider Revolution acts as a container for slides, which in turn act as containers for layers. Modules are created and edited with the module editor.
A "module" is a single, self contained piece of content. You can think of this as being similar to the way a post or page in regular WordPress is a self contained piece of content.
A module can represent any kind of content Slider Revolution is capable of creating, such as a slider, carousel, hero unit, navigation menu, posts display and so on.
Multiple modules can be combined to form rich content such as complete sites and landing pages. requirements.
Furthermore, if you have created a cluster effect you want to reuse, you can save it as a custom preset and deploy it again anytime.
This guide encompasses all the available configuration options that you can use to tailor or create your unique cluster effects.
Before delving into the details, let’s briefly go over how you can manage your custom presets.
Note: To access every option mentioned in this guide, choose an existing The Cluster layer, go to the Layer Options tab, The Cluster sub-section, and finally the The Cluster Setup panel:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/clustersetuppanel.jpg)
Managing Custom Presets
After customizing a cluster effect it can be saved as a custom preset in the Cluster FX Library for use later. Let’s see how.
Saving a Custom Preset
To save a custom preset, click to expand the Cluster FX Library and Custom Presets, then click the line labeled Custom Settings (Click to Save as Preset):
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/saveclusterpreset-1.jpg)
The line will turn blue and placeholder text such as “Give name” or “custom” will appear:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/namepresett.jpg)
Replace that text with a name for your custom preset, then click the tick at the end of the line:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/savepreset.jpg)
Your custom preset will be saved and you’ll now see it listed under Custom Presets:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/presetsaved.jpg)
Deleting a Custom Preset
If you need to delete a custom preset, hover over it, then click the bin icon at the end of the line:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/deletepreset.jpg)
Customizing Cluster FX Attributes
Below the Cluster FX Library you’ll see tabs for 8 categories of options you can modify in order to create a custom cluster effect:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/clusterfxtabs-1.jpg)
Those categories are:
- Main – sets the most broad options for the cluster effect.
- Scene – allows you to configure a cluster layer’s scene.
- Gravity – enable and configure gravity points.
- Spawn – the number of particles, where the particles appear, and how they begin moving:
- Particles – the size range of particles.
- Movement – ongoing movement of the camera and particles.
- Interactions – make the cluster effect respond to mouse movement in various ways.
- VFX – apply additional visual effects to your cluster.
Let’s step through the options available under each category and learn how to use them.
Note: At any time you can click the Restart Animation button, (located below the category tabs), to play your cluster effect from the beginning:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_restart_animation.jpg)
Main
The main category sets the most broad options for the cluster effect:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_main_catagory.jpg)
It contains the following options and panels:
Speed
The Speed option controls how fast the cluster particles move:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/cluster_main_speed_option.jpg)
It is set as a percentage value between 1%
, the slowest speed, and 100%
, the fastest speed.
Limit Cluster
Toggle the Limit Cluster option to ON to restrict the movement range of the cluster to within a sphere:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_limit_cluster_on.jpg)
Note: This limit sphere is positioned at the midpoint of the effect’s Gravity Points, which will be covered later.
Limit Amount
If the Limit Cluster option is set to ON, the Limit Amount option appears. It sets the size of the limit sphere, i.e. the maximum distance particles can move away from its center:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_limit_amount.jpg)
The option can be set from 1
, which creates the smallest limit sphere, through to 15
, the largest limit sphere.
Noise Setup Panel
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_noise_setup_panel.jpg)
Noise
Toggle the Noise option to ON to introduce “noise”, i.e. randomness or turbulence, into the movement pattern of particles:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_noise_on.jpg)

, the weakest influence, through to 500
, the strongest influence.
Scene
The Scene category of options allows you to configure a cluster layer’s scene:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_scene_category_option.jpg)
It contains the following options and panels:
Adjust Scene Panel
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_adjust_scene_panel.jpg)
Every cluster layer has a scene, which is a kind of container in which the cluster effect sits. You can think of it as a portion of 3D space dedicated just to the cluster effect.
Inside the Scene is the cluster effect and a virtual camera that views the cluster. Both the scene and the camera can have their angles manipulated to alter what you see of the cluster.
Show Helper
Toggle the Show Helper option to ON:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_show_helper.jpg)
And a visual representation of the scene’s 3D positioning will appear on the canvas:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/cluster_3d_helper_example.jpg)
The helper consists of three lines, each representing an axis. Green is the vertical, or Y, axis. Red is the horizontal, or X, axis. Blue is the depth, or Z, axis.
Angle
The Angle option allows you to roll the cluster’s angle from left to right or vice versa:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_angle.jpg)
The value can be set in degrees, within a range between -360deg
and 360deg
.
Decrease the value to angle the cluster to the right, i.e. roll clockwise. Increase the value to angle the cluster to the left, i.e. roll counter clockwise.
Tilt
The Tilt option allows you to tilt the cluster forwards or backwards:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_tilt.jpg)
The value can be set in degrees, within a range between -90deg
and 90deg
.
Decrease the value to tip the cluster forwards. Increase the value to tip the cluster backwards.
Adjust Camera Panel
The Adjust Camera panel allows you to position the camera capturing the cluster:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_adjust_camera_panel.jpg)
Keep in Centre
Toggle the Keep in Centre option to ON and, regardless of what other camera adjustments you make, the camera will stay pointed at the center of the scene:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_keep_in_center.jpg)
Horizontal
The Horizontal option allows you to move the camera side to side:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_adjust_camera_horizontal.jpg)
The value can be set as a number, within a range between -20
and 20
.
Decrease the value to move the camera left. If Keep in Centre is set to OFF, this will make the cluster appear to slide right. If Keep in Centre is set to ON, this will make the cluster appear to rotate counter clockwise around its center.
Increase the value to move the camera right. If Keep in Centre is set to OFF, this will make the cluster appear to slide left. If Keep in Centre is set to ON, this will make the cluster appear to rotate clockwise around its center.
Vertical
The Vertical option allows you to move the camera up and down:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_adjust_camera_vertical.jpg)
The value can be set as a number, within a range between -20
and 20
.
Decrease the value to move the camera down. If Keep in Centre is set to OFF, this will make the cluster appear to slide up. If Keep in Centre is set to ON, this will make the cluster appear to tip forwards.
Increase the value and move the camera up. If Keep in Centre is set to OFF, this will make the cluster appear to slide down. If Keep in Centre is set to ON, this will make the cluster appear to tip backwards.
Zoom
The Zoom option allows you to move the camera forwards and backwards:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_adjust_camera_zoom.jpg)
The value can be set as a number, within a range between -60
and 25
.
Decrease the value to move the camera back. This will make the cluster appear to move forward.
Increase the value to move the camera forward. This will make the cluster appear to move back.
If Keep in Centre is set to ON, if the camera zooms in past the center of the scene it will appear to quickly make a 180 degree turn and start zooming out again, looking at the center from the opposite side of the cluster.
Reset
Click the Reset button to set the scene back to its defaults:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_adjust_camera_reset.jpg)
This will set Angle to 0deg
, Tilt to 10deg
, Keep in Centre to ON, and Horizontal, Vertical and Zoom to 0
.
Performance Settings Panel
The Performance Settings panel contains just the one option, Max DPR, as described below.
Max DPR
The Max DPR (maximum device pixel ratio) option allows you to set the quality of the cluster effect:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_performance_setting_panel.jpg)
It can be set with a value of either 1
, 2
or 3
. The default value is 1
, but increasing to 2
or 3
will generate a higher quality cluster. However, this may have performance impact.
Gravity
The Gravity category of options allows you to enable and configure gravity points:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/cluster_gravity_option.jpg)
Gravity points are positions in 3D space that act as attractors or repellors for particles in the cluster.
A gravity point will pull particles towards itself, or push them away, with a strength that depends on its Mass setting, as detailed below.
Edit Gravity Points
Click the Edit Gravity Points button:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_edit_gravity_points.jpg)
And the Gravity Point Editor window will open:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/cluster_gravity_point_editor_window.jpg)
Gravity Point 1, 2, 3
There are up to three Gravity Points available, each of which can be activated in the scene by toggling its switch to ON:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_gravity_point_1_2_3_on.jpg)
Position & Mass
After activating a gravity point, use the four fields below its switch to set its position and mass.
The first three options set the point’s X (horizontal), Y (vertical), and Z (depth) positions:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_gravity_point_horizontal_vertical_depth_fields.jpg)
And the fourth option sets the point’s Mass, i.e. the strength with which it attracts particles towards its position, or repels them:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_gravity_point_mass_option.jpg)
Enter a positive number to attract particles, and a negative number to repel them.
Spawn
The Spawn category of options allows you to configure the number of particles added to a cluster layer, where the particles appear, and how they begin moving:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_category.jpg)
It contains the following options and panels:
Spawn Width
The Spawn Width option sets the amount of space in which particles are allowed to spawn:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_width.jpg)
It can be set between 1
, the narrowest space, and 100
, the widest space.
Note: This option only appears if Spawn Form is set to On Globe, In Globe, or In Circle.
Amount
The Amount option sets the number of particles that will be added to the cluster:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_amount.jpg)
It can be set between 5
, the minimum particle count, and 3000
, the maximum particle count.
Spawn Form
Particles are initially formed in the shape of a 3D object, after which they will begin moving. The Spawn Form option determines what that initial shape will be:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_form.jpg)
It has seven possible settings: On Globe, In Globe, On Border, Random, Random 3D, In Line and In Circle.
On Globe spawns particles on the outside of a sphere:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_form_on_globe.jpg)
In Globe spawns particles inside of a sphere:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_in_globe.jpg)
On Border spawns particles along the border of the layer boundary:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_on_border.jpg)
Random sets random X and Y positions for the particles:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_random.jpg)
Random 3D sets random X, Y and Z positions for the particles:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_random_3D.jpg)
In Line spawns particles along a 2D line:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_in_line.jpg)
In Circle spawns particles along a 2D circle:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_spawn_in_circle.jpg)
Mirror
The Mirror option allows you to mirror, or duplicate, the Spawn Form you have selected. If set to 2, 4 or 6, that number will be the number of spawn forms seen:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_mirror_options.jpg)
For example, if using the In Circle spawn form, setting Mirror to 4 will create 4 lines of particles:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_in_circle_mirror_4.jpg)
Note: This option only appears if Spawn Form is set to On Globe, In Globe, In Line, or In Circle.
Spawn Position Panel
The Spawn Position panel allows you to set where the initial spawn form should be positioned in the scene.
X, Y, Z
Use the X option to set the spawn form’s horizontal position, the Y option to set the vertical position, and the Z option to set the depth:

Particle Behavior Panel
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_movement_particle_behavior_panel.jpg)
Type
The Type option controls how particles move across their lifetime. It can be set to either Continuous, Sinus or Lifetime:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/03/cluster_movement_type-1024x312.jpg)
Continuous spawns particles once only then keeps them moving at a continuous flat rate.
Sinus also spawns particles once only, but then moves them at an undulating rate according to a sinus wave.
Lifetime spawns particles that live for a limited time, then respawns more particles.
If you choose this setting, four to five additional options will appear below, with which you can configure the lifetime particle behavior:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_movement_type_lifetime.jpg)
Transition
The Transition option controls particle opacity over their lifetime:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_movement_transition.jpg)
Fade In will make particles slowly fade in, but quickly fade out when they die.
Fade Out will make particles slowly fade out as they die, but quickly fade in when they spawn.
Fade In & Out makes particles slowly fade in when they spawn, and slowly fade out as they die.
Life Length
The Life Length option controls how long a particle lives after spawning:
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_movement_life_length.jpg)
It can be set between 1, the shortest life, and 20, the longest life.
Life Gradient
If Life Gradient is toggled to ON, each particle will gradually change its color through the range set in the Main Color/Gradient option (found under the Design Panel in the Particles category):
![](https://www.sliderrevolution.com/wp-content/uploads/2023/04/cluster_movement_life_gradient.jpg)
Periodic Spawn
