Can anyone recommend some nice settings for brick / clay tiles

[Matt Sugden]

I'm working on about my 100th house!! but this one is slightly different in that the client is asking me to move the sun in also sorts of different (unflattering) places using the daylight location system. The results are that I'm getting very unpredictable results with my bricks and roof tiles material. Mostly the roof tiles. In some cases the roof is white, others pink, but generally over bright and over exposed. The difference between highlight and shadow is far too pronounced. It's frustrating as the texture map I'm using is terracotta colored, but the roof never looks this colour. Anyway, I was wondering if anyone could suggest some setting for ref glossiness, or fresnel reflections, to try and improve the overall look. I typically find I have to over darken textures to stop them being over bright in v-ray, do others find they have to do this aswell?

My bricks are currently just a diffuse map, and a bump map, nothing fnacy
The roof is, diffuse, bump and ref map which is the same as the bump but set at 50%, and ref gloss of 0.4.

One thing you could try if you are getting awkward reflections of the sun on your roof is to unlink the reflection glossiness and highlight glossiness values. Leaving the highlight glossiness at 1.0 will mean you still get the reflection of the environment but without the specular highlight from the sun. You could experiment with other values too to get the look you want.

Also, you might find for this type of lighting situation using an HDRI would give you much more flattering results than the sun/sky system.

You could also adjust down the receive GI setting in the vray properties of your roof.
