Mirror settings?

[do_ob]

So I'm curious about this, I've seen some videos and screen shots where people had full reflections in mirrors. And a few group members also told me they have full reflections.

I've messed around with settings but with no luck.

Problem - My mirror reflections don't have objects in them, I only see clean ground and vehicles, NO trees, NO grass, etc.

Is there a setting for it or am I missing something?

 

PS: Yes, yes I've tried repair etc. etc.
