Thanks ynsaen, So it's not me. That's a small comfort. You say 'a tad'. I've just been messing around and find that values of 50% are making it look better. Although, that's probably misleading. The main problem here seems to be the floor. I tried another room I had set up and found the same thing - the glare from the floor is overwhelming. And, in the case of the 1st room, I have a small spot which will be used for a wall-light (which I haven't got around to building yet). When I switch this off and halve the values, things look normal (P4-normal) again. So, what ought I to do. Reduce specular values? I'll play around some more, but it looks like I'll be including P5 light sets too. A bummer, since there will already be a dozen P4 ones. mac
