Description

AudioReactiveFX provides a set of audio reactive Niagara particle effects plus a few other Niagara systems that do not react to audio and can be used as filler patterns in a scene. The asset pack was designed to be used for live music events or rendered music videos. The effects can be used out of the box but if you start playing around with it, you will discover sheer endless possibilities. A blueprint to enable audio capture in a map is also included for ease of use.

The asset pack contains 22 effects, which have between 20 and 90 parameters for styling, each. The majority of parameters (except things like materials) can be animated in the sequencer. The pack is built in a modular fashion with lots of additional Niagara modules, materials and material functions to be reused. Everything is procedural, thus, meshes can easily be replaced by other meshes without the need for UV mapping.

Update 1.3

Troubleshooting

Audio reactive niagara systems can not be used in UE 5.2 due to a bug. You need to upgrade to 5.2.1 for it to work again.

In UE 5.1 that prevents the effects from being used in a packaged game when async loading is enabled. it is recommended to use UE 5.0 or disable async loading.

see the thread for the workaround here: https://forums.unrealengine.com/t/crash-when-packaging-a-project-containing-niagaraaudiospectrum-in-ue5-0-1/552399/4
