I’m trying to learn rendering lighting way… but having some issues pushing it further.

Where are the shadows?
Yeah it looks really weird because there’s no reflections from objects or softshadows.
Thank you very much.

You can try out two things, add a skylight to your scene, this will also render soft directional shadows where objects get close together. Or you can do what Koola describes in his thread and work with a reflector plane. This way he was also able to achieve super nice, subtle contact shadows
