In this video, Ashif Ali demonstrates the new Data Channel experimental feature in Unreal Engine 5.3 Niagara, which allows you to combine different particle effects like smoke and fire in a single simulation. By utilizing this feature, you can emit both smoke and fire from a single particle system and control them independently. He walks through setting up the fluid source attributes and temperature values to separate and control fire and smoke effects in a fluid simulation, offering a lot of creative flexibility. This feature is perfect for creating complex effects like explosions, fire, and smoke interactions.
Key Points:
- Data Channel Setup: Turn on the “Write to Data Channel” for your emitter to activate this experimental feature in Unreal Engine 5.3.
- Combining Fire and Smoke: By using the Fluid Source Attribute, you can combine fire and smoke in the same simulation and control them independently.
- Particle System: The Fountain emitter is used as a default to show how the feature works, allowing both fire and smoke to emit from the same system.
- Temperature Control: Adjust the temperature values for each emitter to control whether it emits smoke or fire, offering flexibility for different visual effects.
- Color-Coding: Use color coding (red for fire and white for smoke) to easily differentiate between the two particle systems.
- Fluid System: The fluid simulation is set up to emit both fire and smoke by tweaking the density and temperature values of each emitter.
- Independence of Effects: Each effect (fire and smoke) can be simulated and adjusted independently, making it easy to create complex simulations.
- No Need for GPU Emitters: The great part about this feature is that CPU-based particle systems can be used, no need to switch to GPU emitters.

Additional Notes:
- Multiple Emitters: You can place multiple emitters with this feature to have them interact with each other, enhancing the realism of your simulations.
- Experimentation: This feature offers great experimentation potential, allowing for unique effects like explosions, fires, and other fluid-based simulations.
- Temperature Values: Fine-tuning temperature can significantly change how particles behave, making it essential for controlling fire and smoke behaviors.
- Performance: This feature works seamlessly with CPU-based systems, so there’s no need to worry about switching to GPU-based emitters for this effect.
