The special effects in the film were created this week. There is a story where the little prince uses magic to disappear to trick people. Here is the disappearing magic I wanted to show with a particle effect.

There is a new particle system in UE4 called Niagara. The Niagara VFX System is one of two tools you can use to create and adjust visual effects (VFX) inside Unreal Engine 4 (UE4).

Firstly, I created a blank system. Since the character as a whole is going to disappear, the particles should be generated from the character. Here I used a mesh emitter. I exported a separate static pose from Maya to be used as an emitter for the particles.

The generated particles need some movement and variation, and I control the movement mainly through a Curl Noise Force. And a colour curve to control the colour change of the particles.

This is the final result.
