- 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 regulate the size.
- 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 size 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 size alongside the X-axis. |
| Scale Y | Units the size alongside the Y-axis. |
| Scale Z | Units the size alongside the Z-axis. |
Management Scale Utilizing Dynamic Parameters
Dynamic parameters can be utilized along side scale modifiers to regulate the size of a Niagara system over time. This may be helpful for creating results equivalent to scaling up or down, or for animating the scale of a particle system primarily based 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 choosing “Add Dynamic Parameter.” Set the info kind of the parameter to “Float.”
Modifying Scale Over Time
After getting created a dynamic parameter, you need to use it to switch the size 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 regulate the size. You possibly can then use the “Curve” property to specify how the size will change over time.
For instance, you could possibly create a curve that begins at 0 and ends at 1. This could trigger the size of the Niagara system to extend from 0 to 1 over time. You possibly can additionally create a curve that oscillates between 0 and 1. This could trigger the size 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 can too use dynamic parameters to regulate the size of a Niagara system primarily based on its age or velocity. To do that, create a brand new curve that maps age or velocity to a scale worth. You possibly can 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 primarily based on numerous 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 listing.
5. Configure the Mesh Scale Modifier parameters:
| Parameter | Description |
|—|—|
| Mesh | The mesh to be scaled. |
| Scale | The dimensions issue to be utilized to the mesh. This is usually a fixed worth or pushed by an expression. |
| Bindings | Bindings to exterior variables that may management the size issue. |
As soon as configured, the Mesh Scale Modifier will dynamically scale the required mesh primarily based on the required 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 subject, kind within the expression you need to use to scale the particle system. For instance, to scale the particle system primarily based on the gap to the digicam, you could possibly use the next expression:
Scale = DistanceToCamera * 0.1
5. Set the Scale Mode
Within the Scale Mode dropdown listing, 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: Means that you can specify a customized scale expression for every route.
