Same issue here. And on the floor plan too (which isn't rendered at all). So it can't be the sun. But I'll check some more.
Edited: I just did. It really looks like there is a pinkish tint to gray colors when I publish from Archicad 11 to PDF. (I mean the colors 92 etc. in the old AC9 etc color table). They are supposed to have equally balanced RGB values and should print gray.
I guess this has something to do with color profiles. Does anyone know if Archicad's output is color profiled any way?
