Hi All!
I hope in your help!
I notice that every materials with white color is rendered in grey... With vray i didn't have this problem: a white obj was rendered white... Not grey, maybe thanks to the possibility to set white Balance in camera? In arnold i don't find parameters about white Balance, iso and so on like vray.
So, That's a workaround to make materials as white plastic, white metal or white ceramic?
Than a lot for your help.
Gianluigi.
What are your Color Management settings? Are you using ACES?
Hi,
thanks for your reply.
No Aces... this is an image about my Color Management Settings... Thnaks again.
Thanks a lot for your great support.
Really i always had strange grey materials... now is the first time that i have something near a white color (not pure white but similar... light gray). Maybe my problem, in more complex scenes, is something about the enviroment surround (reflection or other things)... i'm new to Arnold and i'm switching from the photographic style of Vray.
The first image is with StandarSurface on sphere, lambert default on ground and default SkyDome.
The second image is with StandarSurface on sphere, lambert default on ground and Area Light.
Do you think the result is correct?
It could be great to simulate a White Pure Metal... but with this behaviour is difficult for me...
Maybe if you increase base_weight to 1 it might give you more of what you would like to see?
Either way, I wholeheartedly recommend moving to ACES as it will give you a more accurate color display with no incorrect color values.
Thanks. Do you have some advice about the ACES settings for Color Manage Tab Preferences? Can you make a screen of you Color Managemente Setting?
Otherwise, here a test with my actuale Color Management Settings and StandardSurface with Base Weight to 1... too much grey... mah.
Could it be the HDR map that you are using? The exposure of some HDR maps are not correctly set and need adjusting in the skydome light (increase exposure 1 stop).
There is a screengrab of the Color Management settings in the link that I sent.

Same issue, it is like white is no more white but the white become light grey.
Even in Specular, Transmission, Subsurface, Coat, ecc.. color it's impossible to do it white.
Usually if you put your color in HSV chanel with S: 0 and V: 1 it become pure white but now it become light grey with the same parameter.
