First set anisotropy
to 0.0 again, and
also refl glossiness to 1.0.
Trace reflections
and trace refrac-
tions are pretty
simple; turn calcula-
tion on by checking
check box or off by
unchecking check
box.
The cutoff param-
eter is a threshold
value for V-Ray to
trace reflections
any further or not.
Try a value of 0,7
on the current im-
age. Increasing the
threshold can speed
up rendering when
you are using lots
of reflections in the
scene.
Double sided: please
refer to the manual.
