Tom, Mihai and all .r2 file gurus.
Is it possible to use the r2 file system to replicate a ramp shader?
If I layer multiple bsdfs with different 0' & 90' colours, which use r2 files that overlap, would that give me the same control as a ramp shader effect?
eg:-
layer 1 r2=90 60
layer 2 r2=65 30
layer 3 r2=35 0
etc
There aren't any r2 files in the material database, which have a second numeric different to zero, so I'm really guessing here.
In my tests, a material will render with r2 values above 90'. Is there an angle limit for the fresnel effect?
Many thanks in advance,
Tim.
