This tutorial shows how to add a night-sky to your comp using FLUX in After Effects CC 2019.
It's a sequel to "Tutorial: 360° Landscapes with FreeForm Pro + GEOLayers 2 + After Effects CC."
Follow that tutorial first to set up your 360° landscape, and then you can add your sky into the same scene.
Hosted by Charles Yeager (yeagerfilm.com), we learn how to use the 3D fractal flames features of FLUX to generate and composite our night sky. FLUX supports Flat, 360 Mono and Stereo formats.
