The pack includes Houdini-made fire and smoke effects that can be used for UE projects.
SideFX has released Village Fire Pack, a new VFX pack for Unreal Engine that contains AAA-quality smoke and fire assets made by Technical/VFX Artist Ben Christensen.
The pack includes a Houdini file with smoke and fire presets that were featured in the Village Fire tech demo, showcased during Unreal's recent live stream titled "The Magic of Houdini". Additionally, the pack comes with a simplified Unreal Engine 5 project that shows the assets in-game.
Please note that the environment geometry shipped with the Fire Pack UE5 project is intended to help you identify the fire assets with what you see in the demo video. The environment geometry itself is not useable as a game asset and is not intended for re-distribution.
