Hi Thorvald,
in the roof surface properties, change the entry under "texture set".
Regards,
Jens
Do not click on the button "Textureset". Just click on the button with the yellow flag in the corresponding slice below.
Hi Thorvald,
you can make your own texture, and store it in Gif\Freitext\textur_0...9.
These textures are shown in 1x1 m.
If you only need them for 1 project, you can save them in a temp folder, and overwrite the existing files. These 10 texture sets were made for this use.
Copy an other texture file, change the color in any picture editor, and save it as "Freitext\textur_0...9"
there is no picture file named "metall cladd 1". This is the english name for the texture set.
The real texture is in the Gif folder, and named "picturename.bmp"
Change one of the bmp's and save it as "\Freitext\textur_0.bmp"
You have PSP7! It can do a lot more than only change brightness and contrast. Take some Sunday afternoons, and learn the other 9999 features. 
PSP7 is some years ago, now I have version 11.
But I'm sure, changing colors was already possible with version 7.
It may be a little more comfortable in the new version.
Aha, I couldn't find it in the menus - then I was reading "Umschalt+U" and then my best guess was that this would be "Shift+U" - and yes it was!! 
And now I see, that it is already black, because the values are 0,0,0. It just doesn't look like a black steel plate, because there some light on it.
