Hi Marcus, For examples of how to set the colour have a look at the osggeometry example.

So I have taken a look at the osg file I get for my Scene. There is no part for an ColorArray oder something like this. Everything is "fine" until I add a stateset to a child. Attached is the important part of the osg file before and after setting the stateset. Perhaps someone cann help me because I can't get any further. I also tried to set a ColorArray, but I don't know how. All I have are two nodes with the read object files and I can't just do node->setColorArray...

Converting to .osg will enable you to go in add an back in the > colour array which is supposed to be there.
