Refraction passes black instead environment?

[digitarch]

Hi alle Vray pros, i have following problem with the vraymtl refraction:

white background (color mapping don´t affect background)
vray sky via skylight environment override

problem: glass object showing black instead of background...

tried the reflection/refraction exit color = white
tried several vray object properties (affect....)

anybody any idea?

check your glass material if it has enough raytrace depth.
