White walls in MaxwellRenderer

hi!

I've been trying maxwell but have a little problem with white walls ( they are sort of burn out !)... i've tried to change iso, but i don't think it's there where i should look !!!

Well, I do not use Maxwell but I have read several suggestions for other rendering apps that you should never use pure white (255,255,255 RGB value). Give it like 250 all three (or even a bit less) and you will never notice that it is not white.

As gai suggests, it may well look burnt our if your using pure white. Personally i find something around 235,235,235 works quite well.

thanks; I was using something like 240 but it is obviously not enough. i'll try with a lower value .

I never go above 220,220,220 for whites.(sometimes even 205,205,205 when the scene is brightly lit in exteriors).
When the white material has a lot of reflection and/or refraction (glass) assigned, you especially need to be careful not to use high RGB's, because you risk to break the law of conservation of energy. Reflecting/refracting more light than you put in is physically impossible and will always look wrong.
