Derek Kirk shows how to get perfect reflections and lighting from a background image backplate using Redshift.
Check out this new tutorial from Derek Kirk (Effectatron), which shows how you can get a backplate background image to create perfect reflections into your scene.
The tutorial runs through how to create a Sci-Fi scene with an ocean reflecting the background image you set.
Instead of Dome lights and a backplate, Kirk uses Area lights with textures to create perfect controllable reflections.
