Too many objects causing lighting problem

[anthonyfoster]

Hi all,

 

I'm creating a large supermarket interior/exterior scene and I'm getting a problem with a grey or fogged effect on some frames of a camera animation. See screen grabs at http://forums.cgarchitect.com/71371-grey-fogged-frames-lighting-problem.html

 

I've been trying lots of things to solve it and I've narrowed it down to something to do with too many objects in the scene. In the supermarket there's obviously lots of aisles, if I turn all or some off, hey presto the problem frames are fine.

 

Can anyone help or a least hazard a guess at why its happening?

 

Cheers,
