Hello,
I have bumped into this problem recently with an interior render. i have i camera looking over the room and out of the window which are double glazed.
I have standard glass setting, fresnel reflections, glass is 99%refractive, with just a little blue tint in it through fog option, affect alpha checked....
Now....both in vray render elements and plain TIFF output (with alpha preserved) i get the ALPHA BLACK AND WHITE!!! although i suppose it should be greyscale to preserve the reflections on it.......
so whn i use this alpha map in PS as an alpha mask co i wanted to put some bacground behind the windows....then due to blacke and white alpha all the reflections from the glass panes disappear ..
Can anyone please suggest where am I going wrong here?
Thankx
Martin
