no not at all in fact it seems that light will not pass through any object that has transparency when rendering buy again shows up fine in the viewport so perhaps a render setting is the problem ?

ye sure here they are I didn't change anything on any of the settings its just the mental ray arch and design think glass I haven't modified it in anyway and when I did to try and solve the problem ive come up empty handed

this has been really annoying me when trying to light this simple room I cannot get the light to pass through my window, I've tried every type of light as well as mental ray the only time it seems to work is when I choose ray traced shadows but I don't want to use that as it produces very hard edges. Strange thing is it will show the light passing through in the viewport but when rendering it doesn't. Any help would be appreciated. Thank you
