How to make a glass window in Vizard

[chris_user]

hope anyone can help me with my problem;
when I apply the mirroring effect, the mirroring looks fine, but the reflected model is way too bright.

this line is the reason for the good looking mirror effect, but it also blows out the placed model if you take a direct look

viz.MainView.getHeadLight().ambient(1,1,1)

is there a possibility to exclude the effect for the model?
hope anybody can help

thanks in advance
