In the tutorials of KeyShot 5 there is a Settings tab in the Project window. I'm using KeyShot6 and there is no such Settings tab. Where can I adjust the Ray Bounces, for example?
That is because KeyShot 6 has another tab for this. You'll find all necessary in the tab 'lighting '. There you can use presets with several options and values for ray bounces, shadow quality and indirect reflections.
On the last pages in the 'what's new' PDF you'll find all UI changes.
Hope that helps
