just a quick question. When I do a viewport render, I like the reflection I have on glass (picture 1). However when I do a final render, I get a really weird looking reflection (picture 2). I'm not using any lamps or area lights, just planes set with emissions. Anyone know why and can offer any advise?

    $\begingroup$ Check if there's an emission plane hidden in viewport but renderable. Note also that view angle between 2 renders doesn't match a bit $\endgroup$

    $\begingroup$ Ahh i figured it out, my geometry had a dip in it which was causing that weird shape in the reflection $\endgroup$

    $\begingroup$ Also check that the number of subdivisions is the same for preview and render. $\endgroup$
