Customization Options

1. Adjusting Update Interval for Performance

By default, the BP_Interaction component uses the Tick() function, which runs every frame. This ensures precise and frequent updates, but it may impact performance in complex scenes or on lower-end hardware.

To optimize performance, we provide an adjustable variable: UpdateInterval.

What is UpdateInterval?

• Default value: 0.01 This means the system updates 100 times per second, ensuring smooth and highly responsive interactions.

• You can increase this value to reduce the frequency of updates and improve performance. For example:

  • 0.02: Updates 50 times per second.

  • 0.05: Updates 20 times per second.

How to Adjust the UpdateInterval

1. Select the actor with the BP_Interaction component.

2. In the Details Panel, find the UpdateInterval variable under the component settings.

3. Adjust the value as needed:

   • Lower values (e.g., 0.01): Higher update frequency for smoother interactions.

   • Higher values (e.g., 0.05 or above): Lower update frequency for better performance.

2. Material Instance Settings

• Customize interaction properties directly in the material instance:

  • InteractionRadius: Controls the area affected by the player's proximity. Default is 100.0.

  • InteractionStrength: Adjusts the intensity of grass interaction.

  • InteractionSharpness: Determines how the effect fades at the edges.
