Dynamic Parameters in UE5 Niagara
This tutorial explains the new Dynamic Parameter features in Unreal Engine 5.1 materials and how to drive them from Niagara particles.
Use it to control erosion, color and UV animation per particle, and see the related posts below for more UE 5.1 features.

Video Title: New Dynamic Parameters in Unreal Engine 5.1 – Explained
Introduction:
- The video discusses new dynamic parameters introduced in Unreal Engine 5.1, focusing on materials and how they work.
- The host, Ashif Ali, starts by introducing the new feature and provides an overview of how these parameters have changed in the latest version.
New Features in Dynamic Parameters:
- New Dynamic Parameters:
- In Unreal Engine 5.1, dynamic parameters now support RGBA values, a feature not available in previous versions.
- Instead of appending individual values, you can directly input RGB and RGBA values in the material editor.
- The new version allows for more straightforward adjustments to these values, enabling easier particle and material manipulation.
- How RGB Works:
- The RGB and RGBA values can now be directly assigned without needing to append multiple values together.
- You can manipulate the color intensity of particles, making them brighter (using 1, 1, 1 for white) or dimmer (0, 0, 0 for black).
- Using Dynamic Parameters in Particles:
- The video explains how the new system allows for easier usage of RGB and RGBA in materials, including particle effects.
- With the new setup, you can connect a sphere mask directly to the RGB output without needing additional nodes or workarounds.
- Example:
- Ashif demonstrates the use of the radial node to adjust the radius and density, showing how the RGB values directly impact the visual results in real-time.
- The dynamic parameters simplify this process, but the link between RGB and particle behavior still exists, even though it could have been implemented more independently for more flexibility.
Conclusion:
- The feature is useful, but the current linking of RGB values in dynamic parameters could be improved for greater independence and flexibility.
- Ashif wraps up by noting that the new dynamic parameter system allows for better and faster material setup and particle management in Unreal Engine 5.1.
