VFX graph to trigger audio

Hi,
We are working on an Output Event feature to ease the retrieval of the spawn context output. It will be a part of 2020 cycle release but I can't provide you a more precise ETA yet.

Meanwhile, using 2019.3 LTS, if you want to synchronise a sound and a VFX, there are two main solutions :
- Control your SendEvent to the VisualEffect by script (for instance, with a Burst block in spawn context) and play your sound
- Use a timeline and "Visual Effect Activation Track" to control when particles are spawned (but it will not be so random).
These two approaches have been used in the spaceship demo.

We are also preparing a breakdown presentation to explain how we have synchronized and played the VisualEffect in this demo.

 

Indeed, prior to this week's update, the SparkleBurstAuto was performing the spawn independently from the Sound activation. I made a change so that the random delay is now computed in C# instead of VFX Spawn. This enables also the use of flashing spotlights to emphasize on the sparkle bursts.

As Paul said, our future ability to output events from a VFX instance shall help us move back all the random delay computation back to VFX and catch all this sync points at the component level to perform sound play and light flashing.
