How to make Smoke in Spark AR Studio

This tutorial will teach you to use a feedback loop with delay frames, applying custom distortions to each iteration of the loop and controlling the visual output to your liking.

Inspiration

The new Render Pass feature on Spark AR has allowed for a whole new range of post-processing visual effects to be built. This is just one of the many possibilities we've stumbled across and wanted to share with the community :)

What it does

It takes a frame or any scene item and generates visual smoke for it via distortions. The effect can easily be taken off the smokey path to obtain completely different results!

How I built it

It's mainly built using the Render Pass feature as well as the in-built Spark AR Studio AR Library's Texture Distortion Shader, which we modify a bit for more control.

What's next for How to make Smoke in Spark AR

Hopefully some new effects from people discovering the set up! A few ideas on how to use it are provided at the end of the tutorial ;)
