Live HDRI Edit

Hezer Hajrullaaga say: Since R19 came out, I was utilizing spherical option in camera, for live creation and editing HDRI maps. What this setup gives you is unlimited power to see your scenes, and/or light setups directly within cinema 4d, without using 3rd party plug ins. Setup is just for demonstration, you will definitely create more complex setups, or simply you can use camera in your scene, and have the second panel opened, with interactive render applied.
