I normally use mental ray and I know how to tweak the settings I need to.

For a current project I've decided to have a go with vray and solidrocks. It's a Meieresque house so there's lots of white materials (my favourite colour. So far I've been very impressed with using sr but I have a question on overexposed areas. I can tick the box and see a big red patch where it's over exposed but I can't see anything in SR to be able to adjust that. I've tried auto exposuer and auto WB but I'm still blowing out areas.

Jerome,

I think part of the competition rules ask not to post the images anywhere other than the official forum so here's the link to the tests so far.

I'm quite happy with them for a first try but I would like to have a deeper blue for the sky.

Patrick, your pics looks cool !

My little opinion :
First one have some king of magenta into it...

you can check your cams like this (please make a copy of your scene...)
- turn off vignetting (you'll able to add it again in photoshop if needed finally)
- make some tries with camera white balance to day light and neutral, to see if it helps

If you've made a autoWhite balance in solidrocks, play with options named "ignore alpha pixels" and whole image to see wich one is better.

I had used the white balance and noticed the magenta tint that came from it. I'll play with it a bit more.

The one thing I'm having trouble with is getting a vray image to look as good as what I can do with mr.
