Has anyone tried to use the reflection or highlight feature of raytracing? If so which did you find to work better?
Yup, it's at the bottom of the first page of the sheet he gave us today!
It can be used on both turtle as well as the patches.
raytracing: set-reflection 0.2 <-- this reflects 20% of the light
raytracing: set-highlight 0.4 30 <-- bright spot with brightnes 0.4 and size 30
It depends on what you are trying to achieve, but for me I found that I didn't want that much of a highlight.
I found that highlight works much better for what I was doing.
