material modification?

[ralbia]

I take advantage of it to ask for another thing. .
Once you insert the windows in my 3d I would like to change material but at the time when I go into the set and in the "model" and deseleziono uses material object to insert my glass disappears and I become all of the same color.. I would like to change only the infix.. is it possible?

verify that in the status bar, near the material is checked or not materials:able those of the list. After that, from window settings, you can change every minimum element of the window
