not getting rid of prepasses

all visible objects have standard materials, reflections are globally disabled, gi is off, no lights in scene, default light off - still vray computes prepasses.

vray takes hidden object reflection-settings into account to set rendering parameters, even though reflections and gi are globally disabled.
very confusing.

;-( andre

It appears that even if reflect/refract turned off, interpolated glossies are still calculated to some extent (they go faster than if they were on).

and they are calculated even though no object with interpolated glossies are visible.
