Render Lighting setting question Carrara 6 Pro
I am rendering simple technical animations done in Carrara 6 Pro.
I happy with the look, and render time. The final render is being done to Quicktime Animation 1080P.
I have done 4 or 5 clips. I use 50% ambient Light as set in the Scene tab, and the single default light when you open a new session.
Render time is not an issue for me so I am trying to set very high quality images.
One thing I don't understand.
In these 4 different sessions, they have different available options in the render window.
Chosing Lighting Pixel accuracy, shadow accuracy, improved edges are available in a couple, but some I have to select "Skylight" or "indirect" light to have these options not grayed out. I would prefer not change my global light just before rendering to get these options.
I looked in the manual. I must be doing something different between these sessions, but I don't see it.
