This wonderful clouds simulation was created by Fabio Nascimento with JangaFX's EmberGen and rendered with Blender Cycles. What's even more impressive, the artist is a hobbyist just testing out the EmberGen trial version, JangaFX's flagship real-time fluid simulation tool for VFX creation.
Jason Key, a Principal VFX Artist at JangaFX, was the one who shared this work originally posted on the dedicated Discord server. You can join the server and learn more about EmberGen and GeoGen as well as see other artists' works by clicking this link.
