problem of contrast with Vray

[rachelC]

Hello,

 

could someone explain me why i am not getting very much contrast in this render please?

 

Many thanks

are you using logarthmic exposure?

[rachelC]

i am using no exposure at all.

A lot of times Vray renders will look washed out, even if not using Max's exposure control. Using Vray's exponential color mapping will add to the problem. I usually use HSV Exponential to keep the colors strong, but always need to do some adjustment in Photoshop no matter what.

what about Vray's GI Envirment Override? ..or bright multiplier.

 

maybe delete some of the thing out of your scene, and post the file for us to look at. you might need to link to it.

[rachelC]

i wouldn' t mind if you would have a look at it. here is the file.

I am using the basic version.

Thank you,

I'm not seeing any shadows...if you don't have\don't want a light in there for shadows, create one and then turn it off, and then try rendering.

[rachelC]

thought i have shadows?

[Chad Warner]

Nevermind then, If you don't have a light in there, the default lighting will be really washed out like that.

[rachelC]

you are right. my main light was only at 0.1. i increase it and this is the result.

this is my first exterior rendering with vray so i am not too sure of how to use it. thank you for your help.

Check out this site: http://www.vray.info. There are several tutorials there that will be a huge help in getting you started.

[rachelC]

again, thank you

are all your different bounce stages set to multiplier of 1. i find that reducing primary bounce to .8 and the secondary bounces to about .5 or.6 gives a bit better contrast. still as already mentioned, i'm trying to find ways of getting stronger contrast.

I had a look at your scene and the only way I could get it to render properly was to merge the building into a new scene and put the model at the proper scale. I converted it to inches. When I merged the scene it was very, very small. This can create all kinds of problems.

 

It seems fine now, however. Give it a try!

tried to download your model but i culdnt. Check the enviroment and effects window under rendering (or press 8) if the tint in the global lighning is set to black, put the intensity of your light to 1 instead of .1 and check that global ilumination is turned on, an enviroment in vray is set to 1 and with a good enviroment color, (i use a color between white and very light blue)
