How to set up HDRI environment in Corona for C4D?

To use a custom HDR image as environment in your scene (for direct visibility and lighting):

  1. Add a Sky object (Create > Environment > Sky)
  2. Create a Corona Light material (Material editor > Corona > Light Material)
  3. Load the HDRI of your choice as the texture of the Corona Light material
  4. Apply the Corona Light material to the Sky object
  5. To make the environment visible only to specific ray types (direct visibility, GI, reflections, refraction), you can add Corona Compositing tag to the Sky object (Tags > Corona Tags > Corona Compositing)
