Animation for a Glass Company

Check out this animation I just finished for a client…

Smooth and simple… but the reflection doesn’t look very realistic. It looks like ball lightning trapped inside the windows - until it disappears - when you realise it was actually a ‘reflection’. I think you need to use a textured world background with an image texture of a sky or a landscape. When that reflects it’ll look more natural (no matter what the glass is used for).

Yeah I was thinking about using a world texture, but this is for an intro to their website, and I’m not sure if I want the background to match or not yet. The customer loves it so far, and he just wants me to have it fly through their slogan before the the logo at the end. Thanks for the tips!
