Basic colour change issue with mentalray
show user profile  Lukel
Hi folks,
I know this must be a basic one. (as always coming from me.)
Have a sun/sky lighting setup with MR. Lighting a dark grey building
facade using an A+D shader.

The grey is almost black but under the lighting setup I have that dark
grey appear very light. I understand the colour will change with different
lighting but what would I need to be doing to keep it essentially the same as
it is in the material editor?
Many thanks.
Lukle.

Sounds a bit stupid, but adjust your lights so that the colour looks the same as it does in the material editor. :)

This will sound a bit stupid as well i think.
Regardless of the lighting conditions a colour will always be dark grey though.
In my facade the dark grey is quite light.

Technically you're right. It is 'always' dark grey. But what do you think makes it grey? Light.
At night, colours are more desaturated because less light bounces off the surfaces. Thus we see a vibrant red during the day, but a far more muted red at night.

So you DO need to change your lighting if you want it to be darker. Max can't always behave like the real world, it needs your input.

Cheers,
Lisa

Or look at your exposure control settings, that will cause this kind of problem too.
