I made those shaded boxes after the rest. I can’t remember what I could have done to accidentally have made them shaded. I’ve looked at various settings and they all look ok.
Thanks in advance.
Figured I should add in another question.
I deleted the shaded boxes. However, I seem to have deleted something necessary for the last “regular” block before the shaded. I can no longer select it as a face. Why can/can’t I delete to prevent a removal of a “face”?
In Edit mode select all verts with A and Ctrl-N and then Remove Doubles with W. Then in F9 buttons, Links and Materials tab click SetSolid. Tell us if that doesn’t work.
