To switch scale by way of Blueprint, observe these steps:
- Create a Blueprint actor or inherit from an current Niagara system.
- Within the Blueprint graph, right-click and seek for “Set Scale” node.
- Drag and drop the “Set Scale” node into the graph.
- Join the output of the “Get System” node to the “Goal” enter of the “Set Scale” node.
- Create a float variable to manage the dimensions.
- Join the float variable to the “Scale” enter of the “Set Scale” node.
- Compile and save the Blueprint.
As soon as the Blueprint is created, you may place the actor within the scene and management the dimensions of the Niagara system by modifying the float variable within the Blueprint.
Scale Property Desk:
| Property | Description |
|---|---|
| Scale | Units the general scale of the Niagara system. |
| Scale X | Units the dimensions alongside the X-axis. |
| Scale Y | Units the dimensions alongside the Y-axis. |
| Scale Z | Units the dimensions alongside the Z-axis. |
Management Scale Utilizing Dynamic Parameters
Dynamic parameters can be utilized together with scale modifiers to manage the dimensions of a Niagara system over time. This may be helpful for creating results reminiscent of scaling up or down, or for animating the dimensions of a particle system based mostly on its age or velocity.
To regulate scale utilizing a dynamic parameter, first create a brand new dynamic parameter within the Niagara editor. This may be achieved by right-clicking within the parameters panel and deciding on “Add Dynamic Parameter.” Set the information kind of the parameter to “Float.”
Modifying Scale Over Time
After getting created a dynamic parameter, you should utilize it to change the dimensions of a Niagara system over time. To do that, create a brand new scale modifier within the Niagara editor. Within the scale modifier’s properties, choose the dynamic parameter that you simply need to use to manage the dimensions. You may then use the “Curve” property to specify how the dimensions will change over time.
For instance, you possibly can create a curve that begins at 0 and ends at 1. This may trigger the dimensions of the Niagara system to extend from 0 to 1 over time. You might additionally create a curve that oscillates between 0 and 1. This may trigger the dimensions of the Niagara system to extend and reduce over time.
| Dynamic Parameter | Scale Modifier | Curve |
|---|---|---|
| Float | Scale | Begins at 0 and ends at 1 |
You too can use dynamic parameters to manage the dimensions of a Niagara system based mostly on its age or velocity. To do that, create a brand new curve that maps age or velocity to a scale worth. You may then use this curve within the scale modifier’s “Curve” property.
Make the most of Niagara Mesh Scale Modifier
The Niagara Mesh Scale Modifier permits you to dynamically scale Niagara meshes based mostly on varied parameters. This allows you to create results that reply to gameplay occasions, consumer enter, or different system variables.
Steps to Use the Mesh Scale Modifier
1. Create a brand new Niagara system or open an current one.
2. Within the Niagara Editor, choose the Emitter you need to modify.
3. Within the Particulars panel, navigate to the Modifiers part.
4. Click on the Add Modifier button and choose Mesh Scale from the record.
5. Configure the Mesh Scale Modifier parameters:
| Parameter | Description |
|—|—|
| Mesh | The mesh to be scaled. |
| Scale | The size issue to be utilized to the mesh. This generally is a fixed worth or pushed by an expression. |
| Bindings | Bindings to exterior variables that may management the dimensions issue. |
As soon as configured, the Mesh Scale Modifier will dynamically scale the desired mesh based mostly on the desired parameters, permitting you to create a variety of scaling results.
Apply Scale Expression to Cascade
To use a scale expression to a particle system in Cascade:
1. Open the Particle System Editor
Choose the particle system you need to edit and click on the **Edit** button within the Particulars panel.
2. Choose the Emitter
Within the Particle System Editor, choose the emitter that you simply need to scale.
3. Open the Scale Module
Within the Modules panel, click on the **Scale** module to open it.
4. Add a Scale Expression
Within the Scale Expression discipline, kind within the expression you need to use to scale the particle system. For instance, to scale the particle system based mostly on the space to the digicam, you possibly can use the next expression:
Scale = DistanceToCamera * 0.1
5. Set the Scale Mode
Within the Scale Mode dropdown record, choose the mode you need to use to scale the particle system. The next choices can be found:
- Uniform: Scales the particle system uniformly in all instructions.
- X, Y, Z: Scales the particle system within the X, Y, and Z instructions independently.
- Customized: Lets you specify a customized scale expression for every path.
6. Regulate the Scale Curve
The Scale Curve permits you to management how the dimensions of the particle system adjustments over time. To regulate the dimensions curve:
