Glass material becomes white (Cycles) I made some glasses for my character, and gave the lenses a glass material, which works fine, except for the fact that at some angles, when rendered, the lenses turn completely white. I don't think this is reflection, because it does not gradually turn white. One angle it's fine, and turn it ever so slightly and it goes completely white. 



I have no clue what could be causing this. 

EDIT: I have posted the Blend file on the Blend Exchange so you guys can check it out!
@EVERYONE I messed with the IOR slider on the glass material and now it doesn't happen anymore... I will still post the blend file in case but I think it's fixed!
