I have a problem with one of my SU models. When I open the file the colour of my window frame appear pink (instead of black) and the glass colour is changed as well.
When i change it, save, and re-open the file… it change again! Does anyone know how this can happen. I work in China, so my colleagues who worked with the same file before might use a Chinese version of SketchUp. (version 8 or higher)
I hope you guys know what the problem can be, thanks!
As a wild guess, is Fog turned on?
Anssi
no, it is not the fog… the first screenshot i made when SU was not responding, that’s why you see the foggy effect 
Have you made sure that the facing faces are actually front faces and not back faces? No sure why it would make a difference, but it might. (Turn the mode to “Monochrome” from the “Styles” toolbar - everything should be light; dark faces are back-to-front)
Thanks for your suggestion… I tried, but it isn’t the problem! 
are all materials applied to ‘faces’ or are some applied to groups, components or even layers?
the other area to check is the actual material names, is there a conflict?

The only other thing I can think on is that you have used an identical material somewhere else and edited it; unless you make the material “unique” if you change it in one place, it will change everywhere.
