I’m working on a project involving Oculus and unreal engine 4, and I’m trying to figure out how I can animate the brightness of the particles to an audio file. (I don’t know if it is possible)
Would anyone be kind and send me in the right direction.
Thanks in advance,
I am not sure how sound is currently handled in ue4 and what you have access to, in most sound APIs you can fetch a lot of additional data from a sound being played. This is used for instance in media players to do interesting graphical feedback. Not far from what you are planing.
I guess the first thing needed is to find a common ground between the particle system and the sound system. That is probably trough a blueprint? One that reads information from a specified sound and feeds that sound into the data for the particle system?
Step one, see if we can fetch the sound data at a tick event.
Wierd transformations and transforms and magic touch on the data.
Step two, hook up the data to the particle system after the magic touch.
In this question there is blueprint showing you how to retrive some of the data that would be needed for this.
