Find out what light portals are and when and how to use them in Cinema 4D.
Are you rendering an interior scene? Light portals are an essential part of getting great renders, but also decreasing noise and render-times too. Portals will tell the rendering engine how to sample light more efficiently. They are a smarter way of working rather than just brute-force sampling the entire scene which wastes calculations and time. These types of lights are great for bringing light into an enclosed scene, like a room or other interior spaces.
