The materials (surfaces) you see while working in Archicad use the OpenGL (Basic) settings as set in the surface settings.
When you render, it uses the Cinerender settings for those surfaces.
If you are changing the OpenGL/Basic settings, you also have to switch to the Cinerender settings and make the same changes there.
This can get a little complicated as the Cinerender settings are much more complex than the OpenGL/Basic ones.
There is a 'Match Settings' button - but be aware that this will reset the Cinerender settings to the very simple ones used in the OpenGL/Basic settings.
NOTE: you can also set the OpenGL/Basic settings to match the Cinerender ones if you want to.
If you have amended the Cinerender settings and it is still rendering as grey, then there must be a setting in the Photorendering settings that is affecting this.
Offhand I can't think what it would be.
Try different rendering scenes to see if that makes a difference.
